Your first step is to install Xcode.  This will be on the system discs
that came with your Mac.  Xcode includes gcc, but is not installed by
default.  Once you run the installer, you should find gcc in
/usr/bin/gcc, which is automatically in your PATH.

You can then run your program by using the commands

        gcc -o hello hello.c
        ./hello

Alternatively, you can launch Xcode and select "New Project" from the
File menu.  Then click on "Command Line Utility" in the sidebar of the
window that comes up, and select "Standard Tool" from the available
templates in the window.
