[ITP - Lecture 03] Introduction to C/C++
C++ is an object-oriented programming language that is an enhanced version of C. A C++ program consists of three main parts: preprocessor directives, the main function, and C++ statements. Preprocessor directives provide instructions to the compiler, such as including header files. The main function indicates the beginning of the program and contains the main body of code. C++ statements are the individual lines of code written within the main function and end with semicolons.

OVERVIEW OF ‘C’ PROGRAM
This document provides an overview of C programs. It discusses that C was introduced in 1978 and is a portable, structured programming language that allows programs to be efficiently extended through additional functions. A C program consists of sections for documentation, linking, definitions, global declarations, the main function, and additional subprograms/functions. The main function contains declaration and executable parts, while additional functions make up the subprogram section. Executing a C program involves four steps - creating the program, compiling it, linking it with library functions, and then executing the program.

C is a general-purpose programming language widely used for system programming. It was created in the 1970s at Bell Labs and has since become standardized. The document provides an overview of C, including its history, basic program structure, data types, operators, and control structures. It also presents examples of simple C programs and explains key elements like comments, functions, variables, input/output, and escape sequences.
Introduction of c language
C is mother language of all programming language.
It is a system programming language. It is a procedure-oriented programming language. It is also called mid-level programming language.
C evolved from a language called B, written by Ken Thompson at Bell Labs in 1970. Ken used B to write one of the first implementations of UNIX. B in turn was a descendant of the language BCPL (developed at Cambridge (UK) in 1967), with most of its instructions removed.
So many instructions were removed in going from BCPL to B, that Dennis Ritchie of Bell Labs put some back in (in 1972), and called the language C.
The famous book The C Programming Language was written by Kernighan and Ritchie in 1978, and was the definitive reference book on C for almost a decade.
The original C was still too limiting, and not standardized, and so in 1983, an ANSI committee was established to formalize the language definition.
It has taken until now (ten years later) for the ANSI ( American National Standard Institute) standard to become well accepted and almost universally supported by compilers.
C++ basics
The document provides an introduction to programming in C++, covering topics such as:
- The software development cycle of compiling, linking, and executing code.
- Integrated development environments (IDEs) that support the entire development process with features like editing, compiling, debugging etc.
- Key components of a program including keywords, variables, operators, and constructs.
- Object oriented programming concepts in C++ like classes, objects, and inheritance hierarchies.
Prog1-L1.pdf

C is a general-purpose programming language originally developed in the 1970s to write operating systems. It has since become widely used for various applications. Key features of C include being small, structured, producing efficient programs that can run on many computer platforms. The document then provides an example "Hello World" C program and discusses some basics of C syntax and comments.
Introduction to cpp language and all the required information relating to it
C++ is an object-oriented programming language developed in the early 1980s as an extension of C with additional features like classes, inheritance, and function overloading. A simple C++ program prints a string to the screen using the cout output stream and iostream header. C++ programs typically contain functions, comments, and use operators like << for output and >> for input.
Lecture 2.8 Arrays.pdf
This document discusses arrays in C++. It defines an array as a collection of data of the same data type stored in consecutive memory locations. Arrays allow accessing elements via an index, with the first element having an index of 0. Arrays can be declared by specifying the type, name, and number of elements. Individual array elements are passed by value to functions while the entire array is passed by reference, allowing the array contents to be modified. Function prototypes can specify arrays without size for parameters.
Lecture 2.2 Default Arguments.pdf
This document discusses default arguments in functions. It explains that if not enough parameters are passed to a function call, the rightmost parameters will take on their default values as specified in the function prototype. Default values can be constants, global variables, or function calls. The function prototype sets the default values, so a function call with fewer than all parameters will use the defaults for the omitted rightmost parameters. Examples are given of calling a function with 1, 2, or all 3 parameters, with the rightmost omitted parameters taking the default values specified in the prototype.

Lecture 2.6 Function Templates.pdf
This document discusses C++ function templates, which provide a compact way to create overloaded functions that generate separate functions for different data types. It explains that function templates begin with the keyword "template" followed by type parameters in angle brackets. The type parameters act as placeholders that get replaced by the actual type in a function call. An example is provided of a template function that squares its input value, showing how the template type T gets replaced by int when called with an int parameter.
Lecture 2.4 Recursion.pdf
This document discusses recursion, which is a technique for solving problems by breaking them down into smaller subproblems and solving those subproblems recursively until reaching a base case. It provides examples of recursive functions like calculating factorials and the Fibonacci sequence. Recursion involves functions that call themselves, breaking a problem into smaller calls until a base case is reached. While recursion and iteration both involve repetition, they differ in how termination is handled - recursion relies on reaching a base case while iteration uses an explicit loop condition. Both techniques can result in infinite loops if not implemented properly.
Lecture 3 Structures in C++.pdf
Structures in C++ allow users to aggregate data of different types together. Structures can contain members of basic types like int and float, as well as pointers. Structures are defined with a tag name followed by member names and types. Structure members are accessed using dot (.) or arrow (->) operators. By default, structures are passed by value but can be passed by reference to avoid copying. C-style structures lack interfaces so any implementation changes require all dependent code to also change.
Lecture 2.5 Function Overloading.pdf
Function overloading allows functions to have the same name but different parameters, allowing functions to perform similar tasks like squaring integers and floats. Overloaded functions are distinguished by their signature, which is based on the function name and parameter types where order matters. Name mangling encodes the function identifier and parameters to ensure type-safe linkage and the proper overloaded function is called.
Lecture 1.11 Break and Continue Statements.pdf
The document discusses the break and continue statements in programming. The break statement provides an immediate exit from loops like while, for, and do/while as well as switch statements. Control then continues with the statement after the structure. The continue statement causes an immediate jump to the start of the next iteration of a loop like while, for, or do/while, skipping the rest of the statements for the current iteration. Both statements can be used to alter the normal flow execution of loops and switches.
Lecture 2.1 Functions.pdf
Functions allow programmers to organize and reuse code. They can be either predefined functions from a standard library or custom functions defined by the programmer. A function contains a block of code that performs a specific task. Functions make programs more modular and reusable by allowing code to be called multiple times. Local variables inside functions are only known within that function. Parameters pass outside information into the function. Functions are defined with a return type, name, and parameters and called by writing the name and passing arguments.
Lecture 1.5 Variables.pdf
This document discusses variables in programming. It explains that variables are locations in memory where values can be stored, and common data types include integers, characters, and floating point numbers. Variables must be declared with a name and data type before use. Multiple variables can be declared in one statement separated by commas. Variable names correspond to locations in memory, and each variable has a name, type, size and value. When a new value is assigned to a variable, it overwrites the previous value stored there. The document also discusses using the input stream extraction operator (>>) to get user input and store it in a variable, and the assignment operator (=) to assign a value to a variable.
Lecture 1.2 Basics of a typical C++ Environment.pdf
This document outlines the basics of a typical C++ environment, including the main components of a C++ system like the programming environment, language, and standard library. It describes the common file extensions for C++ programs and the typical phases a C++ program goes through: editing, preprocessing, compiling, linking, loading, and executing. It also provides a diagram illustrating how these phases work together from editing the code on the disk through compiling, linking, loading into memory, and executing on the CPU. Finally, it recommends downloading and installing the Dev-C++ IDE to get started with a C++ environment.
Lecture 2.3 Inline Function.pdf
Inline functions allow the compiler to copy the function code into the program instead of making a function call to reduce overhead. The inline keyword is placed before a function declaration to suggest to the compiler that it should inline the function code. Inline functions are good for small, often-used functions as it avoids the overhead of a function call.
Lecture 1.8 Conditional Structures.pdf
This document discusses conditional structures in programming, including the if structure which executes code if a condition is met and skips it otherwise. It also covers equality and relational operators that are used to evaluate conditions, as well as the ternary operator that allows assigning a value based on whether a condition is true or false. The document was prepared as part of a lecture on conditional structures.
Lecture 2.7 Type Conversion in C++.pdf
This document discusses type conversion in C++. It explains that argument coercion forces arguments to be of the proper type, such as converting an integer into a double. It notes that conversion rules usually convert arguments automatically but changing from double to integer can truncate data. It also discusses that mixed type arguments go to the highest type through promotion. Finally, it outlines the two main types of conversion: coercion/implicit conversion and truncation/explicit type conversion using casting operators like (int).
Lecture 1.6 Arithmetic and Relational Operators.pdf
This document discusses arithmetic and relational operators in C++. It describes common arithmetic operators like multiplication, division, and modulus and their order of operations. It also covers relational operators like greater than, less than, equal to, and not equal to. These relational operators are used to compare values and form conditional expressions in C++. Standard algebraic operators have corresponding C++ operators for performing arithmetic calculations and comparisons in code.
Lecture 1.7 C++ Keywords.pdf
C++ keywords are reserved words that have specific roles in the language and cannot be used as identifiers. This document lists the keywords common to C and C++ like auto, break, case, char, as well as C++ only keywords like bool, catch, class, const_cast. It also defines an identifier as a variable or function name and encourages subscribing to the author's channel for more programming videos and courses.
Lecture 1.4 Escape Sequence.pdf
Escape sequences are combinations of characters that have meanings other than their literal representation. An escape sequence in C++ starts with a backslash and is followed by a character that indicates the escape sequence. Common escape sequences include \n for newline, \t for tab, \r for carriage return, and \a to beep. Escape sequences are often used within strings.
Lecture 1.9 Switch Structure.pdf
This document provides an overview of switch structures in programming. A switch statement tests a variable against multiple case values and allows executing different code blocks depending on which case matches the variable's value. The switch statement contains case labels for the possible values, and an optional default case to handle non-matches. Break statements are needed after each code block to exit the switch properly. The document encourages subscribing to the author's channel for more programming videos and courses.
Lecture 1.10 Repetition Structures.pdf
The document discusses different repetition structures in programming including while, do/while, and for loops. It explains that a while loop checks the condition at the beginning, and the loop body may or may not execute depending on the condition. A do/while loop is similar but checks the condition at the end, so the body always executes at least once. A for loop also checks the condition at the beginning, and allows initialization and updating of a counter variable to control the number of iterations.
Lecture 0 Object Oriented Programming.pdf
This document outlines a 14-lecture course on object oriented programming in C++. Lecture topics include introduction to structures and functions in C++, object oriented concepts like classes and objects, features like encapsulation and inheritance, pointers and memory management, operator overloading, polymorphism, templates, and exception handling. The course is intended to cover fundamental and advanced concepts in object oriented programming using C++.

Lecture 1.3 A Simple Program to Print a Line of Text.pdf
- 1. A SIMPLE PROGRAM TO PRINT A LINE OF TEXT Lecture 1.3 Prepared by: Mian Saeed Akbar REF:
- 2. 1 // A first program in C++. 3 #include <iostream> 4 5 // function main begins program execution 6 int main() 7 { 8 std::cout << "Welcome to C++!n"; 9 10 return 0; // indicate that program ended successfully 11 12 } // end function main Welcome to C++! Single-line comments. Preprocessor directive to include input/output stream header file <iostream>. Function main appears exactly once in every C++ program.. Function main returns an integer value. Left brace { begins function body. Corresponding right brace } ends function body. Statements end with a semicolon ;. Name cout belongs to namespace std. Stream insertion operator. Keyword return is one of several means to exit function; value 0 indicates program terminated successfully.
- 3. A SIMPLE PROGRAM TO PRINT A LINE OF TEXT Before writing the programs Comments Document programs Improve program readability Ignored by compiler Single-line comment Use C’s comment /* .. */ OR Begin with // Preprocessor directives Processed by preprocessor before compiling Begin with #
- 4. A SIMPLE PROGRAM TO PRINT A LINE OF TEXT Common Input/output functions cin Standard input stream Normally keyboard cout Standard output stream Normally computer screen cerr Standard error stream Display error messages
- 5. A SIMPLE PROGRAM TO PRINT A LINE OF TEXT Standard output stream object std::cout “Connected” to screen << Stream insertion operator Value to right (right operand) inserted into output stream Namespace std:: specifies using name that belongs to “namespace” std std:: removed through use of using statements Escape characters Indicates “special” character output
