Compiling your first C program

Having successfully entered and saved your hello1.c file, it is now time to compile it:

1. In a Terminal, command-line, or console window (depending on your OS), with the current working directory the same as your hello1.c file, enter $ cc hello1.c.
2. Once this is done and you have a new command-line prompt, verify that you have a file named a.out.

You have completed your first compiling phase of the program development cycle.
