C++ Installation

Installing C++

C++ installation uses compilers like GCC or MSVC for development.

Understanding C++ Compilers

To write and execute C++ programs, you need a compiler. A compiler is a tool that translates your C++ code into machine code that your computer can execute. The most commonly used C++ compilers are GCC (GNU Compiler Collection) and MSVC (Microsoft Visual C++).

Installing GCC on Linux

GCC is a popular choice on Linux systems. Use the following command to install GCC:

Once installed, verify the installation by checking the GCC version:

Installing GCC on Windows

For Windows users, GCC can be installed using MinGW or WSL (Windows Subsystem for Linux). Here, we will use MinGW:

  1. Download the MinGW installer from the official website.
  2. Run the installer and select 'gcc-g++' from the package list.
  3. Complete the installation process.

Installing MSVC on Windows

MSVC is part of the Visual Studio IDE, which is a comprehensive development environment for Windows:

  1. Download and install Visual Studio from the official Microsoft website.
  2. During installation, select the 'Desktop development with C++' workload.
  3. Once installed, open Visual Studio and start a new C++ project.

Verifying Your Installation

After installing your compiler, it's essential to verify that it's working correctly. You can do this by compiling a simple C++ program.

Save the above code in a file named hello.cpp and compile it using the following command:

If the installation is successful, you should see Hello, World! printed on your terminal or command prompt.
