Introduction to C++

 

C++ is a powerful, high-performance programming language that builds upon C by adding object-oriented features. It is widely used for system programming, game development, embedded systems, and high-performance applications.

Key Features of C++

• Object-Oriented: Supports classes, objects, inheritance, and polymorphism.
• High Performance: Provides fine-grained control over system resources.
• Rich Standard Library: Includes features like data structures, algorithms, and file handling.
• Portable: Can run on various platforms with minimal modifications.
• Supports Multiple Paradigms: Procedural, object-oriented, and generic programming.

History of C++

• Developed by Bjarne Stroustrup in 1983 at Bell Labs.
• Initially called "C with Classes", later renamed C++.
• Continuously updated, with major versions like C++98, C++11, C++17, and C++20.

Why Learn C++?

• Used in game engines (Unreal Engine), operating systems (Windows), databases (MySQL), and more.
• Provides deeper system control than languages like Python or Java.
• Helps in competitive programming due to its speed and efficiency.

Basic C++ Program

Here’s a simple C++ program that prints "Hello, World!":

#include <iostream>
using namespace std;

int main() {
    cout << "Hello, World!" << endl;
    return 0;
}

Explanation

• #include <iostream>: Includes the input-output stream library.
• using namespace std;: Allows using standard namespace elements like cout.
• int main(): The entry point of a C++ program.
• cout << "Hello, World!" << endl;: Outputs text to the console.
• return 0;: Indicates successful execution.
