How to use a C++ compiler?

The C++ compiler is a tool that transforms C++ source code into executable files. Below are the general steps for using a C++ compiler:

1. Write C++ source code: Create a new file in a text editor, write code using C++ syntax, and save it as a .cpp file format.
2. Open the command-line terminal: Open the command-line terminal or a similar development environment.
3. Switch to the directory where the source code is located: Use the cd command in the command line to navigate to the directory where the C++ source code is located.
4. Enter the compilation command: Type the compilation command in the command line, for example with the GCC compiler you can input the following command:

g++ myfile.cpp -o myprogram

myfile.cpp is the name of your source code file, and myprogram is the name of the executable file you want to generate.

1. Compile: Press Enter to execute the compile command, and the compiler will convert the source code into an executable file.
2. Run the program: Input the name of the executable file in the command line and press Enter to run the program.

You can perform the above steps on operating systems like Windows, Linux, and macOS by simply choosing the appropriate C++ compiler and command line tools.
