🤔 What is C++ Programming? #

C++ is a general-purpose, high-level, and object-oriented programming language that was developed in the early 1980s.

It is an extension of the C programming language and adds support for object-oriented programming features such as classes, inheritance, and polymorphism.

C++ is known for its performance, efficiency, and flexibility, and it is widely used for developing operating systems, embedded systems, video games, web browsers, and financial software.

It is a compiled language that must be compiled into machine code before it can be executed.

👴 Who is the Father of C++?

Bjarne Stroustrup is known as the father of C++.

He is a Danish computer scientist who created C++ in the early 1980s while working at Bell Labs in the United States.

🎰 How C++ Works?

C++ code is typically written in a text editor or an integrated development environment (IDE), such as Visual Studio or Code::Blocks.

Once the code is written, it must be compiled into machine code using a compiler such as GCC or Clang.

The resulting machine code can then be executed by the computer.

💰 Is C++ a open-source?

Yes, C++ is an open-source programming language, and its standard is maintained by the ISO.

The source code of the language is available for developers to download, modify, and distribute, and there are also many open-source C++ libraries and frameworks available.

📄 Hello World in C++

Here's an example of a simple C++ program that prints Hello, World! to the console:

demo.cpp

Copied

#include <iostream>
int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

This program includes the iostream library, which allows the program to print text to the console.

💻 Output

Output

Hello, World!

🤯 Fun Fact

Did you Know?

Some programmers joke that the ++ in C++ stands for more headaches. This is because C++ can be a very complex and challenging language to learn and use, especially for beginners. However, with practice and experience, many programmers come to appreciate the power and versatility of C++ and find it to be a rewarding language to work with.
