An array allows us to store multiple values of the same data type using a single variable name. It represents the data contiguously in memory. We declare an array by specifying its type, name and size. Individual elements can be accessed using indexes and assigned values. Arrays can be passed to functions along with their size.
Introduction of arrays, Declaration of array, Initialization of array, Sorting, Multidimensional array. Some code examples that will make you clear about the concept of arrays.

Arrays allow storing and accessing multiple values of the same data type. A two-dimensional array represents data in a tabular form and can be used to store values in a matrix. It is declared with two sets of brackets and initialized with nested curly braces. Elements are accessed using two indices, such as array[row][column]. Memory for a two-dimensional array is allocated in a contiguous block, with the first dimension iterating fastest.
The document discusses one-dimensional arrays in C++. It defines an array as a group of like-type data where each element is referred to by an index. It describes how to declare arrays by specifying a type, name, and size. Elements in an array are accessed using subscript notation, with the first element having an index of 0. The document also covers initializing array elements either explicitly by assigning each one, or using an initialization list within braces.
C++ arrays allow storing a fixed number of elements of the same type sequentially in memory. Arrays are declared by specifying the element type and number, such as int numbers[100]. Individual elements can then be accessed via their index like numbers[0]. Arrays can be initialized with a list of values or left uninitialized. Elements are accessed using their index and the array name, like n[5] to get the 6th element.

Arrays in C are collections of similar data types stored in contiguous memory locations that can be accessed via indexes, they can be declared with a specified data type and size and initialized with values, and multi-dimensional arrays allow the storage of two-dimensional data structures like matrices through multiple subscripts denoting rows and columns.
The document compares and contrasts arrays and linked lists. It states that arrays provide fast random access but fixed size, while linked lists have flexible size but slower sequential access. It also discusses different types of linked lists and their memory usage.
Structures in C allow the user to define a custom data type that combines different data types to represent a record. A structure is similar to an array but can contain heterogeneous data types, while an array only holds the same type. Structures are defined using the struct keyword followed by structure tags and member lists. Structure variables are declared like other variables and members can be accessed using the dot operator. Arrays of structures and nested structures are also supported.
The document discusses arrays in C programming language. It defines arrays as fixed-sized sequenced collections of elements of the same data type that share a common name.

This document provides an introduction and overview of arrays in C programming. It defines an array as a collection of the same type of data. It describes how to declare and initialize single-dimensional and two-dimensional arrays, including examples. It also provides simple programs to demonstrate summing values in a single-dimensional array and outputting values in a two-dimensional array.
Arrays passed to functions are passed by reference, not by value. When an array is passed to a function, the function receives the address of the first element. Any modifications made to the array elements inside the function are reflected in the original array in memory. Arrays do not need an ampersand (&) when passed to a function. The function prototype only needs to specify the array name without brackets to indicate an array parameter.
Arrays in C allow storing of homogeneous data items in contiguous memory locations. An array variable stores multiple data items of the same data type. Arrays provide advantages like code optimization through accessing elements with fewer lines of code, easy traversal and sorting of data using loops, and random access of any element. The main disadvantage is that arrays have a fixed size set at declaration. Key array terminology includes size, type, base address, index, and range. Arrays can be declared and initialized at the time of declaration or by taking input from the user. Multidimensional arrays like 2D arrays represent data in rows and columns like a matrix.
1. An array is a group of variables of the same type referred to by a common name. Arrays can have one or more dimensions.
2. A one-dimensional array stores elements in contiguous memory locations. Elements are accessed using an index number within square brackets.
3. Common array operations include initializing values, accessing individual elements, searching for elements, finding the maximum/minimum value, and performing element-wise operations on multiple arrays.

The document discusses one-dimensional arrays in C++. It defines an array as a series of elements of the same type that can be referenced collectively by a common name. These elements are placed in consecutive memory locations and can be individually referenced using a subscript or index. The document covers declaring and initializing one-dimensional arrays, accessing array elements individually and collectively, inputting and displaying array elements, and provides examples of programs that work with arrays.
While doing programming in any programming language, you need to use various variables to store various information. Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory.
You may like to store information of various data types like character, wide character, integer, floating point, double floating point, boolean etc. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory.
Pointers are variables that store memory addresses. They can be used to point to other variables in memory and manipulate their values indirectly. The document discusses declaring pointer variables, pointer expressions, pointers with arrays, passing pointers to functions, and dynamic memory allocation using malloc(), calloc(), and realloc(). Pointers allow accessing and modifying values of other variables through memory addresses rather than direct variable names.

Arrays are collections of related data items of the same data type. An array stores elements of the same data type in contiguous memory locations that are accessed using an index. The index is used to access individual elements, with the first element having an index of 0. Arrays can be initialized by assigning values to each element or by prompting for input during runtime using a for loop. Operations on arrays include insertion, deletion, and searching of elements. Searching can be done using linear search, which sequentially compares each element to the search key, or binary search, which divides the array in half and recursively searches within the narrowed range.
1. Arrays allow storing of multiple elements of the same data type under a single name. They can be one-dimensional, two-dimensional, or multi-dimensional. Strings are arrays of characters terminated by a null character.
2. Common array operations include declaring and initializing arrays, accessing elements using indexes, and performing element-by-element operations. Strings have specialized functions for operations like length calculation, copying, comparison and concatenation.
3. Pointers allow working with arrays by reference rather than value and are useful for passing arrays to functions. Structures group together different data types under one name and unions allow storing different data types in the same memory space.
Arrays are a data structure that allow the storage of multiple elements of the same type. They can have one or more dimensions. One-dimensional arrays use a single subscript, while two-dimensional arrays use two subscripts to reference rows and columns. Arrays can be passed as arguments to functions in several ways, including as a pointer, sized array, or unsized array. Arrays are useful for storing and sorting data, performing matrix operations, and storing temporary values in recursive functions. However, arrays have limitations such as a static size, requiring elements to be of the same type, and potential memory issues if not sized correctly.
The document discusses the relationship between arrays and pointers in C programming. It explains that arrays store a consecutive series of variables under a single name, and each element of the array has its own unique memory address. Pointers can be used to reference array elements, where the array name represents the base address of the array and pointer arithmetic allows accessing elements. It provides examples of declaring and initializing arrays, accessing elements using pointers, and how pointers can be incremented or decremented to traverse the array.
This document provides a tutorial on pointers and arrays in C. It begins by explaining what a pointer is, noting that a pointer variable stores a memory address rather than a value. It discusses how to declare pointer variables and how to assign memory addresses to pointers using the address-of operator (&). It also covers dereferencing pointers using the asterisk (*) operator to access the value at a pointer's memory address. The document then discusses how pointer types allow pointer arithmetic to increment or decrement pointers by the size of the type being pointed to. Finally, it introduces how arrays are related to pointers since arrays can decay to pointers to their first element.

Pointers and arrays in memory.
Memory is just a long string of bytes addressed by locations. Variables are represented by their addresses. Programs can also deal with addresses via pointers. Pointers contain the address of the data they point to. Arrays are blocks of contiguous memory that can be accessed using indexes that calculate the address from the starting point. Functions use stack frames to manage local variables that are destroyed when the function exits.
1. Constructors in derived classes are executed after the base class constructor. When an object of a derived class is created, the base class constructor is executed first, followed by the derived class constructor.
2. Destructors in a class hierarchy are invoked in the reverse order of constructor execution. The destructor of the class whose constructor was executed last is called first when the object goes out of scope.
3. The document provides examples of constructors and destructors in single inheritance, multiple inheritance, and multilevel inheritance hierarchies. It demonstrates the order of constructor and destructor execution in various scenarios.
The document discusses multi-level inheritance hierarchies in Java. It provides an example of a multi-level hierarchy with classes A, B, and C, where C inherits from B and B inherits from A. The document then gives a more complex example using classes Box, BoxWeight, and Shipment, where Shipment inherits from BoxWeight, which inherits from Box, and provides code to implement this multi-level hierarchy. It also discusses using super keyword to refer to the immediate parent class and outputs the results of running code for the Shipment example.
This document provides an introduction to object-oriented programming concepts including abstraction, encapsulation, and inheritance. It defines abstraction as identifying an object's crucial behavior while eliminating irrelevant details. Encapsulation ties an object's state and behavior together, keeping them hidden from external code. Inheritance allows a new class to inherit behaviors from an existing parent class, expressing "is-a" relationships. Real-world objects have state represented by fields and behavior exposed through methods.
C programming & data structure [arrays & pointers]MomenMostafa
This document provides an overview of arrays and pointers in C programming. It defines arrays as a series of elements of the same data type. Arrays can be initialized, accessed using subscripts, and their size determined. Multidimensional arrays contain arrays as elements. Pointers offer an efficient way to work with arrays, as array notation is equivalent to pointer notation. Functions can operate on arrays by passing a pointer to the first element as a parameter.
This document discusses data members and member functions in object-oriented programming. It defines data members as variables declared inside a class and member functions as functions declared inside a class. It covers accessing public, private, and protected data members, defining member functions inside and outside the class, and different types of member functions like static, const, inline, and friend functions. The document provides examples and explanations for each concept to help explain how data members and member functions work in object-oriented programming.
Some Basic Concepts of Object Oriented MethodologyManoj Kumar
The document discusses Object Oriented Methodology and modeling. It describes Rambaugh's Object Modeling Technique (OMT) which includes analysis, design, and implementation phases. The analysis phase builds an abstract model of application objects, properties, and behaviors. The design phase optimizes implementation, and implementation creates reusable code. OMT uses graphical notation and three models: object model describing object structures, dynamic model describing time-based changes, and functional model describing data transformations.
This document discusses C++ friend functions and classes. It explains that friend functions have access to private and protected members of a class, but are not members themselves. Friend functions are declared using the friend keyword within the class definition. Friend classes also have access to private members, and are declared using the friend class syntax. Examples are provided to illustrate friend functions for operator overloading and accessing members of multiple classes.
Object oriented methodology & unified modeling languageIsmail El Gayar
The document discusses Unified Modeling Language (UML) and object-oriented methodology. It introduces UML, describing it as the standard language for visualizing and modeling software systems. It outlines the main UML diagram types including use case diagrams, class diagrams, sequence diagrams, collaboration diagrams, state machine diagrams, activity diagrams, component diagrams, and deployment diagrams. The document also discusses key concepts of object-oriented methodology such as classes, objects, attributes, and methods.
An overview of object oriented programming including the differences between OOP and the traditional structural approach, definitions of class and objects, and an easy coding example in C++. This presentation includes visual aids to make the concepts easier to understand.
Static member functions can be accessed without creating an object of the class. They are used to access static data members, which are shared by all objects of a class rather than each object having its own copy. The examples show declaring a static data member n and static member function show() that prints n. show() is called through the class name without an object. Each object creation in the constructor increments n, and show() prints the updated count.
The document discusses templates in C++. It explains that templates allow functions and classes to work with different data types using a single code definition. Template functions are called function templates, and template classes are called class templates. The document provides examples of defining class and function templates, and overloading template functions. It demonstrates how templates can be used to create generic functions that operate on multiple types of data.
The document discusses structures in C programming. It explains that a structure defines a template to group together different data types under a single name. It demonstrates how to define a structure, create structure variables, and access members of a structure using the dot and arrow operators.
This document discusses multiple inheritance in C++. It provides a brief history of multiple inheritance in C++ and discusses some of the myths and controversies around it. It also covers the object model and implementation of multiple inheritance, virtual functions, ambiguities, and overheads. The document concludes that multiple inheritance is not actually that hard to implement or use and does not significantly complicate the language if certain rules are followed.
This document discusses inheritance in object-oriented programming. It defines inheritance as obtaining properties from one class to another. It then describes six types of inheritance: single, multiple, multilevel, hierarchical, hybrid, and multipart. Each type is explained with an example diagram illustrating the inheritance relationships between base and derived classes.
This document discusses object-oriented programming concepts in C++ including classes, objects, inheritance, abstraction, encapsulation, and polymorphism. It defines each concept and provides examples. Some key advantages of OOP mentioned are code reusability, modeling real-world problems effectively, managing complexity, and facilitating incremental development from small to large systems.

- It includes frameworks, class libraries, languages and tools to develop web and desktop applications.
- Programming languages that can be used to build applications include WinForms, ASP.NET and ADO.NET.
This document summarizes different types of arrays in C#:
- There are three types of arrays - single dimensional, multidimensional, and jagged arrays. Single dimensional arrays store elements in a single list, multidimensional arrays store them in a table-like format, and jagged arrays can store elements of different sizes.
- Single dimensional arrays are created using square brackets after the type. Multidimensional arrays use commas inside the brackets to specify multiple dimensions. Jagged arrays are arrays of arrays that can have elements of varying sizes.
- The document provides examples of declaring, initializing, and filling values in each type of array.

This document provides a summary of C# versions and new features introduced in C# 7.0, 7.1, 7.2, and 7.3. It discusses features such as binary literals, digit separators, local functions, out variables, tuples, deconstruction, discards, ref returns and locals, pattern matching, expression-bodied members, throw expressions, and more. It also briefly previews some planned features for C# 8.0 like asynchronous streams/sequences, records, ranges, and nullable reference types.
Arrays in C and C++ allow storing collections of elements of the same type contiguously in memory. Arrays can be declared with an explicit size or implicitly based on initialization values. Array indexes always start at 0. Pointers are frequently used with arrays, as arrays essentially behave like pointers - arrays names represent the address of the first element. Functions can accept arrays as parameters using pointers, allowing the function to access and modify the elements of the passed array.
Constructors initialize objects when they are created and can be used to set initial values for object attributes. Destructors are called automatically when objects are destroyed. This document discusses various types of constructors like default, copy, parameterized constructors. It also covers constructor overloading and destructors.

This document provides an introduction to object-oriented programming in C++. It explains that object orientation involves breaking programs into self-contained objects defined by classes. A class defines the variables and functions of an object, while an object is an instance of a class. The document uses examples like a Car class to demonstrate how to define classes with header and implementation files, and create objects from classes in a main program. It notes that object orientation can make programs easier to understand and reuse code through breaking problems into objects.

It also examines ethics issues around methods for identifying plagiarism in code, and recommends as good practice notifying students of potential mini-vivas in advance and giving them access to annotated transcripts before misconduct hearings. The overall aim is to have a fair and balanced approach that considers the complexities of programming assignments and students' perspectives.
Accessibility Support with the ACCESS FrameworkMichael Heron
The ACCESS Framework aims to improve accessibility support by making it more accessible itself. It uses plug-ins to identify usability issues and automatically make corrections to address them. Users provide feedback to reinforce helpful changes. Evaluation found the framework improved performance on mouse tasks and users understood and accepted its approach after using it. Future work focuses on additional input methods, cross-platform support, and community involvement.
ACCESS: A Technical Framework for Adaptive Accessibility SupportMichael Heron
The document describes ACCESS, an open source framework that aims to provide accessibility support for older and less experienced computer users by automatically configuring the operating system based on a user's interactions. The framework uses plugins that monitor user behavior and can make changes like increasing mouse click thresholds. Experimental results found users found the tool beneficial and non-intrusive. Future work includes adding real-time correction and addressing security/trust issues before broader deployment.
This document discusses authorship and collaboration in multiplayer online text-based games (MUDs). It notes that MUDs have no single author and evolve continuously through contributions from many developers and players over long periods of time. Determining authorial intent is difficult as control and direction change hands frequently. The code infrastructure is built and maintained by many, influencing but not dictating the narrative elements added by others. Players also influence the game's direction through feedback and invested time. Thus MUDs frustrate traditional notions of a fixed work with a single author.
This document discusses object inheritance in systems analysis and design. It covers key concepts like inheritance, composition, aggregation, and the relationships between classes. It explains how inheritance allows classes to inherit attributes and behaviors from parent classes, and how child classes can specialize or extend parent classes through overriding and adding new functionality. The document also discusses the differences between single and multiple inheritance and how inheritance is implemented in languages like Java and .NET.
Rendering involves several steps: identifying visible surfaces, projecting surfaces onto the viewing plane, shading surfaces appropriately, and rasterizing. Rendering can be real-time, as in games, or non-real-time, as in movies. Real-time rendering requires tradeoffs between photorealism and speed, while non-real-time rendering can spend more time per frame. Lighting is an important part of rendering, as the interaction of light with surfaces through illumination, reflection, shading, and shadows affects realism.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

2. Introduction
• We talked about pointers a few lectures ago.
• In this lecture we are going to talk about pointers and
arrays.
• This is a little bit more complicated than working with simple arrays
in Java.
• It is expected you are comfortable with the mechanics of
pointers at this point.
• & is the ‘address of’
• * is the ‘value of’
3. Arrays in C++
• Arrays in Java have a two-step setup process.
• Declare the array object
• int[] myInts
• Create the array
• myInts = new int[100];
• In C++, we can use pointers to do the same two stage
process.
• Declare the array object
• int *myInts
• Create the Array
• myInts = new Int[100];
4. Arrays in C++
• You can also declare an array in C++ in a single step:
• int myInts[100];
• This doesn’t work in Java.
• Arrays in Java are fully fledged objects.
• They have methods and attributes.
• C++ does not provide these for you.
• You have to manually manage their state, size and such.
5. Arrays and Pointers
• When an array is created as a pointer, the pointer
reference is to the memory location of the first element in
the array.
• When using index accessing, the numeric index acts as an offset.
• myInts[3] means ‘get the element three spaces on from the first’
• Exciting Language Feature!
• C++ doesn’t do any compile time bounds checking on arrays.
• If you set an element that is greater than the size of the array, it will write
to that memory location anyway.
• Easy way for things to go weird.
6. Arrays of Objects
• Three step process in Java.
• Declare the array
• Create the array of object references
• Initialize each object reference.
• C++ permits this as a one stage or two stage process.
• Same as creating an array of any other data type.
• The compiler will create an array of objects created using the zero
parameter constructor.
• Hence the importance of a zero parameter constructor!
7. Arrays of Objects
• You can simulate the Java creation process through the
use of an array of pointers.
• Here’s where it gets tricky.
• First we create an array of pointers to objects.
• We then initialise each pointer in that array by creating an object for
it to point.
• The syntax for creating an array of pointers is double asterisks on
the declaration:
• Car **myCars;
8. Arrays of Pointers
Car **myCars;
myCars = new Car*[100];
for (int i = 0; i < 100; i++) {
myCars[i] = new Car(100.0, "Blue");
}
9. Worked Example
• Let’s look at this concept by working through an example.
• We’re going to add a list of all previous owners to our car objects.
• First of all, we need to add an array of strings to our car
declaration.
• We also need to store the size of the array.
• C++ doesn’t do that for us.
• Egads!
10. Worked Example
class Car {
private:
float price;
string colour;
string *owners;
int max_size;
int current_size;
public:
Car();
Car (float, string = "bright green");
void set_price (float p);
float query_price();
void set_colour (string c);
string query_colour();
string to_string();
int query_size();
int query_current_size();
void add_owner (string str);
string query_owner (int ind);
};
11. Constructors
• Our zero parameter constructor should handle the default
case.
• Set the owners array to NULL
• Set the max_size to 0
• Set the current_size to 0.
• Also add in constructor that allow us to set a maximum
size of the array.
• Three parameter constructor.
13. Adding an Owner
• We next need to implement the add_owner method.
• Check to see if our array is full.
• If it isn’t, add the element at the right location.
• Increment the counter by one.
• We need to do our own array bounds validation here.
15. Destroying The Object
• As discussed in an earlier lecture, Java offers garbage
collection to deal with memory leaks.
• C++ doesn’t.
• Whenever we destroy an object, we must also destroy
any dynamically allocated memory.
• Our owners array.
• We do this in the class’s destructor method.
• Same name as a constructor, prefix of a ~.
16. Destroying The Object
• When using delete on an array, we include an empty pair
of square brackets:
• delete [] owners;
• When deleting a pointer to a single data field, we can omit
the brackets:
• delete owners;
• In this case, we need the square brackets in our
destructor.
17. Destroying The Object
Declaration:
class Car {
private:
// Stuff
public:
Car();
Car (float, string = "bright green");
Car (float, string = "bright green", int = 20);
~Car();
// Stuff
};
Body:
Car::~Car() {
delete [] owners;
}
18. Tomorrow’s Tutorial
• The tutorial tomorrow is a group exercise to write, on
paper, the code needed for a simple CD database.
• Directly applicable to your assessment.
• Understanding the nature of pointers and the lifecycle of
an object are important concepts for this.
• The exercise focuses on understanding.
• You don’t need to be syntax perfect.
19. Summary
• Arrays in C++ differ somewhat from those provided in
Java.
• They can be manipulated through pointers in the same
way that simple variable types can.
• Syntax very similar to Java.
• Implications of certain actions are different.
• Additional complexity and power afforded by pointer
manipulation.
