Compiling C++ Code on a Mac using the Terminal and GCC

Compiling C++ Code on a Mac using the Terminal and GCC

---

You can compile C++ code on a Mac using the command line interface (Terminal) and the GCC compiler. Here are the steps to compile and run a C++ program on a Mac:

1. Open Terminal: Go to the Applications folder, then the Utilities folder, and finally double-click on Terminal to open it.
2. Create a new file: Use a text editor such as Nano or Vi to create a new file for your C++ code. For example, to create a new file using Nano, you would enter nano filename.cpp in Terminal.
3. Write your C++ code: Enter the C++ code you want to compile in the file.
4. Save the file: Once you have entered your code, press Ctrl + O to save the file, and then press Ctrl + X to exit the text editor.
5. Compile the code: Use the g++ command to compile your code. For example, to compile the file filename.cpp, you would enter g++ filename.cpp -o outputfile in Terminal. The -o option is used to specify the name of the output file, which will be an executable file that can be run.
6. Run the code: To run the compiled code, enter ./outputfile in Terminal. The output of your program should be displayed on the screen

 

Summary

"Compiling C++ Code on a Mac" is a process that requires using the Terminal and the GCC compiler. The steps to compile and run a C++ program on a Mac include opening Terminal, creating a new file using a text editor, writing C++ code, saving the file, compiling the code using the g++ command, and finally running the code.

The end result is an executable file that can be run and displays the output of the program on the screen.
