7.basic array
This document discusses arrays in C/C++. It defines arrays as structures that contain a collection of related data items of the same type. Arrays have a static size that is set when they are declared. The document outlines how to declare and initialize arrays, including specifying the array name, type, size, and initial element values. It also explains how to access array elements using indexes and the subscript notation.
Array
Arrays allow storing and accessing multiple values of the same type using a single name. Elements in an array are accessed via an index number within brackets. One-dimensional arrays have a single subscript, while multi-dimensional arrays have multiple subscripts separated by commas. Arrays are defined with a type, name, and size, such as int arrayName[size]. Arrays can store user input, be passed to functions, and perform operations like sorting and calculating sums of elements.
Lecture17 arrays.ppt
This document discusses arrays in three sentences:
Arrays are collections of homogeneous data that can be one-dimensional, two-dimensional, or multi-dimensional. One-dimensional arrays store data in a single subscript, while two-dimensional arrays arrange data into rows and columns. Array elements are accessed via an index and each dimension of a multi-dimensional array is identified by a subscript.
Array in-c
This document discusses arrays in C language. It defines an array as a data structure that stores a collection of the same type of data. It explains how to declare, create and initialize one-dimensional arrays with examples. It also discusses the length of arrays and how it is fixed after creation. Finally, it introduces two-dimensional arrays as a list of one-dimensional arrays, and provides examples of declaring and initializing two-dimensional arrays in C.
4 heapsort pq
This document discusses heapsort and priority queues implemented using binary heaps. Heapsort uses a max heap to sort an array in O(n log n) time by repeatedly extracting the maximum element and placing it in its sorted position. A priority queue uses a min heap to retrieve the minimum element in O(log n) time for insertions and deletions by keeping the minimum key at the root.
Array in C
This document discusses one-dimensional and multi-dimensional arrays. It defines arrays as data structures that can hold multiple values of the same type stored consecutively in memory. One-dimensional arrays use a single set of indexes, while multi-dimensional arrays have two or more indexes to access elements. The document provides syntax examples and demonstrates how to initialize, read from, and display one-dimensional and multi-dimensional arrays. It also lists some example programs involving arrays.
Presentation on Heap Sort
Heap data structures can be used for sorting and memory management. Heapsort uses a max heap to sort an array by repeatedly replacing the root with the last element and heapifying the reduced heap. Heaps are also used to manage memory dynamically by allocating and resizing memory blocks on the heap using functions like malloc() and realloc(). Priority queues, which can be implemented efficiently using binary heaps, are used for applications that require fast retrieval of the highest or lowest priority element, such as scheduling tasks.
Pf presntation
The document discusses two-dimensional arrays in C++. It defines a two-dimensional array as an array that consists of more than one row and column. Each element is referenced by two indexes - the first for the row and second for the column. The syntax for declaring a two-dimensional array is shown as datatype arrayname[rows][columns]. Nested loops are used to enter data, with the outer loop iterating through rows and inner through columns. Examples are given to initialize two-dimensional integer and character arrays by enclosing elements in curly braces and apostrophes respectively.

2- Dimensional Arrays
Two-dimensional arrays in C++ allow the creation of arrays with multiple rows and columns. A 2D array is initialized and accessed using two indices, one for the row and one for the column. 2D arrays can be processed using nested for loops, with the outer loop iterating through each row and the inner loop iterating through each column. Functions can accept 2D arrays as parameters, but the number of columns must be specified since arrays are stored in row-major order.
07 Arrays
Arrays are sequences of elements of the same type that can be accessed using an index. Multidimensional arrays have more than one index and are used to represent matrices. Dynamic arrays like lists can resize automatically when elements are added or removed. Common operations on arrays include initialization, accessing elements, iterating with for/foreach loops, and copying arrays.

Lecture 9_Classes.pptx
Classes allow programmers to create new types that model real-world objects. A class defines both data attributes and built-in operations that can operate on that data. C++ provides built-in classes like string and iostream that add powerful functionality to the language. The string class allows easy storage and manipulation of strings, while the iostream classes (istream and ostream) define objects like cin and cout for input/output. These classes provide many useful built-in operations that make input/output powerful yet easy to use.
Computer Programming- Lecture 9

It also describes different methods for measuring algorithm performance, such as theoretical time complexity analysis and empirical measurements. Examples are provided for instrumenting code to count operations. Overall, the document introduces fundamental concepts about algorithms and data structures.
R training3
This document provides an overview of data entry, management, and manipulation in R. It discusses how to create datasets using various functions like c(), matrix(), data.frame(), and list(). It also covers understanding dataset properties, importing data, creating new variables, and subsetting datasets. Useful functions for working with datasets include mode(), length(), dim(), names(), and attributes(). The document shows examples of entering data using these different methods.
Arrays and library functions
Arrays allow storing multiple values of the same type under one common name. They come in one-dimensional and two-dimensional forms. One-dimensional arrays store elements indexed with a single subscript, while two-dimensional arrays represent matrices with rows and columns indexed by two subscripts. Arrays can be passed to functions by passing their name and size for numeric arrays, or just the name for character/string arrays since strings are null-terminated. Functions can operate on arrays to perform tasks like finding the highest/lowest element or reversing a string.
Chap 6 c++
This document discusses arrays and pointers in C++. It begins by explaining that arrays allow storing multiple values of the same type, and that arrays have a fixed size and type after declaration. It then covers how to declare, initialize, access elements of, and iterate through arrays using indexes and loops. Multidimensional arrays are also explained, including how they can be thought of as tables with rows and columns. The document concludes by introducing pointers as variables that store the memory addresses of other variables.

Chapter 11.3
The document discusses different layout managers in Java including FlowLayout, BorderLayout, and GridLayout. It also discusses using panels as containers. Specifically:
1) FlowLayout arranges components from left to right in the order they are added and wraps to the next line when no more space on current line.
2) BorderLayout divides the container into five regions (north, south, east, west, center) with different expansion behaviors.
3) GridLayout places components into an equal-sized grid with a fixed number of rows and columns.
4) Panels can be used as containers within frames to group and layout components, with different panels using different layouts and the panels arranged within the frame
Chapter 11.5
The document discusses event-driven programming in Java. It describes how events are generated from external user actions or the operating system. Events are represented as objects that contain information about the event. Listeners register with event sources to handle specific event types. When an event occurs, the source notifies all registered listeners by invoking the appropriate handler method. Examples of common event types like ActionEvent, ItemEvent and MouseEvent are provided along with the classes, interfaces and methods used to work with them.
Chapter 11.2

Chapter 9.3
A method can propagate an exception back to its caller by including the thrown exception type in its method header. When a method directly throws an exception using the throw keyword, it is the origin of the exception. A method that may throw an exception either directly or indirectly is called an exception thrower, which can be either a catcher that includes a catch block or a propagator that does not contain a catch block.
Chapter 9.4
This document discusses different types of exceptions in Java - checked exceptions which must be handled at compile time, and unchecked exceptions which are not required to be handled. It explains that checked exceptions include subclasses of Exception, while unchecked exceptions include subclasses of RuntimeException and Error. The document also outlines different rules for handling checked exceptions versus unchecked exceptions in methods.
Chapter 9.1
This document discusses exception handling in Java. It defines an exception as an error condition that can occur during program execution, such as division by zero. When an exception occurs, an object of an exception class is created and thrown, terminating normal program flow. The exception can then be caught and handled using try-catch blocks. Java provides built-in exception classes for common errors like input/output errors. All exceptions are subclasses of the Throwable class. The catch block handles the exception, and methods like getMessage() and printStackTrace() provide information about the exception.
Chapter 8.1
The document discusses inheritance in Java. It defines inheritance as creating a subclass from a superclass, where the subclass inherits properties like methods and attributes from the superclass. It provides examples of single inheritance with a Circle subclass inheriting from a Shape superclass. The document also covers when inheritance is used, types of inheritance in Java, superclass and subclass characteristics, and provides code examples of a Rectangle superclass and Box subclass, where Box inherits from Rectangle and overrides some methods.
Chapter 9.0
This document discusses exception handling in programming. It covers catching exceptions with try-catch blocks, throwing and propagating exceptions with multiple catch blocks, and distinguishing between checked and unchecked exceptions. The learning goals are to make code more reliable using exception handling, implement try-catch blocks to catch and handle exceptions, write methods that propagate exceptions, and distinguish checked and unchecked exceptions.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
