1. Contact +919888122255 C++ PROGRAMMING 1. Introduction to C++ C++ is a powerful general-purpose programming language created by Bjarne Stroustrup in 1979. It is an extension of the C programming language with added features such as classes, inheritance, polymorphism, and templates, making it a multiparadigm language. C++ is widely used for system/software development, game development, real-time simulation, and performance-critical applications. https://techcaddcomputerinstitute.com

2. 2. SETTING UP THE ENVIRONMENT • Before writing C++ code, you need to install a compiler. Popular options include: • GCC (GNU Compiler Collection) — commonly used on Linux and macOS • Microsoft Visual C++ — included in Visual Studio on Windows • Clang — a modern compiler for macOS and Linux • You can write C++ code in any text editor (like VS Code, Sublime Text) or IDE (like Visual Studio, Code::Blocks, CLion).

3. DATA TYPES AND VARIABLES DATA TYPE AND VARIABLES • int — integer numbers (e.g., 1, -3) • float — floating-point numbers (e.g., 3.14) • double — double precision floating-point • char — a single character (e.g., 'A') • bool — boolean values (true or false) DATA TYPES VARIABLES • Basic Data Types: • int — integer numbers (e.g., 1, -3) • float — floating-point numbers (e.g., 3.14) • double — double precision floating-point • char — a single character (e.g., 'A') • bool — boolean values (true or false) • int — integer numbers (e.g., 1, -3) • float — floating-point numbers (e.g., 3.14) • double — double precision floating-point • char — a single character (e.g., 'A') • bool — boolean values (true or false)

5. 3. BASIC SYNTAX AND STRUCTURE Every C++ program consists of functions and declarations. The entry point is the main() function. cpp CopyEdit #include <iostream> // preprocessor directive for input-output libraryint main() { std::cout << "Hello, World!" << std::endl; // output statementreturn 0; // exit status }

6. CONTROL FLOW STATEMENTS Loops: Conditionals: • for loop: repeated execution a known number of times • while loop: repeated execution while condition is true • do-while loop: executes at least once • Example: if (age >= 18) { std::cout << "Adult" << std::endl; } else { std::cout << "Minor" << std::endl; } for (int i = 0; i < 5; ++i) { std::cout << i << " "; }

7. BASIC SYNTAX AND STRUCTURE Every C++ program consists of functions and declarations. The entry point is the main() function. #include <iostream> // preprocessor directive for input-output library int main() { std::cout << "Hello, World!" << std::endl; // output statement return 0; // exit status } • Explanation: • #include <iostream> imports the standard I/O library. • int main() defines the main function returning an integer. • std::cout outputs text to the console. • return 0; indicates successful program termination. • V

8. OBJECT ORIENTED PROGRAMMING Classes and Objects class Car { public: std::string brand; int year; void honk() { std::cout << "Beep beep!"; } }; int main() { Car myCar; myCar.brand = "Toyota"; myCar.year = 2020; myCar.honk(); }

9. INHERITANCE class Vehicle { public: void start() { std::cout << "Vehicle started"; } }; class Car : public Vehicle { public: void honk() { std::cout << "Beep!"; } };

11. STANDARD TEMPLATE LIBRARY (STL) Containers: vector, list, map, set, queue, stack • Algorithms: sort, find, reverse, count Introduction The Standard Template Library (STL) is a powerful set of C++ template classes and functions that provide commonly used data structures and algorithms. It is part of the C++ Standard Library and helps programmers write efficient and reusable code without having to implement fundamental data structures and algorithms from scratch. • Iterators: to traverse containers
