Complete Introduction to C++

1. What is C++?

C++ is a high-performance, general-purpose programming language developed by Bjarne Stroustrup. It is widely used in systems programming, game development, real-time simulations, and high-performance applications.

C++ builds upon the C language by adding Object-Oriented Programming (OOP), making it suitable for both low-level and high-level development.

2. Key Features of C++

• Compiled language → fast execution
• Object-Oriented (classes, inheritance, polymorphism)
• Memory control using pointers
• Standard Template Library (STL)
• Cross-platform support

3. Core Concepts

Variables

Used to store data values.

Control Structures

if, else, loops (for, while)

Functions

Reusable blocks of code.

Classes & Objects

Used to implement Object-Oriented Programming.

Pointers

Allow direct memory access (powerful but advanced feature).

4. Basic C++ Example

#include <iostream>
using namespace std;

int main() {
    int x = 5;
    int y = 10;

    cout << "Sum: " << x + y;
    return 0;
}
