Hello Zack,
Thanks so much for looking into this. You indirectly answered one of my
questions -- it's unnecessary to create an xCode project just to build and run
a simple .cpp file (yay!!!).
Having not used Unix except for a very brief period in the early 80s when VI
was a line editor, perhaps you or someone else following this thread can
indulge a few novice questions. I gather VI is better for creating a .cpp file
than the textEdit app? If so, why? What is the process for building and
running from the command line?
Thanks again and best regards.
Geoff
