C++ is a general-purpose programming language created as an extension of the C programming language. It was developed by Bjarne Stroustrup at Bell Labs in the early 1980s. C++ is widely used for systems programming, game development, high-performance applications, and software that needs direct hardware access or real-time constraints.

🔹 Key Features of C++

🔹 What is C++

1. Object-Oriented Programming (OOP)
   Supports classes, objects, inheritance, polymorphism, and encapsulation.

2. Compiled Language
   Code is compiled to machine language, which makes it very fast.

3. Low-Level Memory Manipulation
   Gives access to memory through pointers and manual memory management.

4. Standard Template Library (STL)
   Provides reusable classes and functions like vectors, stacks, queues, maps, etc.

5. Multiple Paradigms
   Supports procedural, object-oriented, and generic programming.

6. Platform Independent (with compiler support)
   Code can be compiled on different operating systems.

🔹 Common Uses of C++

• Operating systems (like parts of Windows, macOS)

• Game engines (Unreal Engine)

• Browsers (Chrome, Firefox)

• Real-time systems (robots, flight simulators)

• Embedded systems

#include <iostream> // Header file for input/output

using namespace std; // Use standard namespace

int main() {

cout << "Hello, World!" << endl; // Output message to screen

return 0; // Exit the program

}
