C++ is a powerful, high-level programming language developed by Bjarne Stroustrup in the early 1980s as an extension of the C language. It is widely used for system/software development, game programming, real-time simulations, and applications requiring high performance. https://techcaddcomputerinstitute.com/best-programming-course-in-jalandhar-punjab.php

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.

2. 2.SETTINGUPTHE
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. DATATYPESANDVARIABLES
DATA TYPE AND 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)

5. 3.BASICSYNTAX
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
Conditional
s:
Loops:
if (age >= 18) {
std::cout << "Adult" <<
std::endl;
} else {
std::cout << "Minor" <<
std::endl;
}
• 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:
for (int i = 0; i < 5; ++i) {
std::cout << i << " ";
}

7. BASICSYNTAXANDSTRUCTURE
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.

int main() {

LIBRARY(STL)
Containers: vector, list, map, set,
queue, stack
• Algorithms: sort, find,
reverse, count
• Iterators: to traverse
containers
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.
