Help Using GCC on Mac OSX

[John-Edward Michaels]

Hello,

I am interested in using a C++ compiler and have been told that gcc is 
the proper way to proceed with Mac OSX.
I suspect that there already is gcc software on my computer when 
installed Developer Tools that came with my Jaguar software update 
package ( OSX 10.2).

Would it be possible to inform me how to find, install and use the C++ 
compiler of gcc? I need to start using it shortly for a computer 
science course I am enrolled in.

Thank you,

Sincerely,

John Michaels
