So I made a C++ program in UNIX using macros. the macros are perfectly working, and I am being asked to use a command to see "the macros replaced by their definition". I do not know what command is the correct to use. the only question I am asking is for you to write the command that is use in cases like this.

Full question is:

"For the code that you wrote in the previous question, use Unix gcc compiler and the

proper command line option to generate the code file to see the macros replaced

by their definition. Highlight the replaced macros in color so that they are highlighted"
