run c++ program in mac terminal

To run a C++ program in the Mac terminal, follow these steps:

1. Open a text editor and write your C++ program. Save the file with a .cpp extension, for example, "my_program.cpp".

2. Open the Terminal application on your Mac. You can find it in the Utilities folder within the Applications folder.

3. Use the "cd" command to navigate to the directory where you saved your C++ program. For example, if your program is saved in the Documents folder, you would type:

cd Documents

1. Compile your C++ program using the g++ compiler by typing the following command:

g++ my_program.cpp -o my_program

This command uses the g++ compiler to compile your C++ program and creates an executable file called "my_program".

1. Once the compilation is successful, you can run your program by entering the following command:

./my_program

This command executes the compiled program and displays the output on the terminal.

1. You should now see the output of your C++ program displayed in the terminal.

Note: Make sure you have the g++ compiler installed on your Mac. If not, you can install it using package managers like Homebrew or MacPorts.

That's it! You have successfully run a C++ program in the Mac terminal.
