How to compile and run C/C++ in a Unix console/Mac terminal?

Question

How can I compile/run C or C++ in Unix console or a Mac terminal?

(I know it, forget it, and relearn it again. Time to write it down.)

Answer 1

This is the command that works on all Unix machines... I use it on Linux/Ubuntu, but it works in OS X as well. Type the following command in Terminal.app.

$ g++ -o lab21 iterative.cpp

-o is the letter O not zero

lab21 will be your executable file

iterative.cpp is your c++ file

After you run that command type the following in terminal to run your program:

$ ./lab21
