* Before learning the C++ language compiler installation process, you must clear a basic concept about assembler, compiler & interpreter

C++ Compiler Installation

The original C++ compiler, called Cfront, was written in the C++ programming language. C++ compilation is considered efficient and fast. Its speed can be attributed to its high-level features in conjunction with its low-level components. Compared to other computer programming languages, C++ can be viewed as quite short. This is because C++ leans towards the use of special characters instead of keywords.

The most commonly used C++ compilers are GCC (GNU Compiler Collection), Code::Blocks and Visual Studio. Here are instructions for installing these compilers on different operating systems:

1. GCC Compiler:

On Linux:

Most Linux distributions come with GCC pre-installed. To check if it's installed, open a terminal and run the following command:

bash Copy Code 
gcc --version

If GCC is not installed, you can install it using your package manager. For example, on Ubuntu or Debian-based systems, you can use:

bash Copy Code 
sudo apt-get update
sudo apt-get install g++

* Use the 'g++' command on the command line to compile C++ programs.

On macOS:

macOS doesn't come with GCC pre-installed, but you can install it using the Homebrew package manager. First, install Homebrew if you haven't already by following the instructions at https://brew.sh/. Then, run the following command to install GCC:

bash Copy Code 
brew install gcc

* On macOS, you can also install the Xcode tool to compile C++ codes.

xcode-select --install

On Windows:

You can install GCC on Windows using the Windows Subsystem for Linux (WSL). First, install WSL following the Microsoft documentation. After setting up WSL, you can use the Linux package manager to install GCC, just like you would on a Linux system.

You can also try this one-line command (In administrator mode) for a quick installation process:

PowerShell Copy Code 
wsl --install -d ubuntu

* After completing the Ubuntu installation, apply the GCC installation code (Linux version).

2. Code::Blocks:

Code::Blocks is an open-source & cross-platform integrated development environment (IDE) used for programming in various programming languages. It provides a user-friendly interface for writing, compiling, and debugging code.

3. Visual Studio:

Visual Studio is also an open-source & cross-platform integrated development environment (IDE) from Microsoft. It is used to develop computer programs, including websites, web apps, web services, and mobile apps.

Compile the C++ File

To compile a C++ file using GCC (GNU Compiler Collection), you need to follow these steps. Let's assume your C++ file is named "hello.cpp":

1. Compile the C++ file using the 'g++' command:

bash Copy Code 
g++ -o hello_world hello.cpp

* Replace "hello_world" with the desired name for the compiled executable.


2. You can then run your program using:

bash Copy Code 
./hello_world

* Replace "hello_world" with the actual name you provided
