You need to have a loop in the code to make
the program repeat.  After you tell user what their letter choice was,
c="";
will clear the original letter out and your loop needs to start
above your message.
I'll offer a suggestion here.
In the msdos/c subdirectory on the simtelnet mirrors you'll
find a file called cguidexx.zip where xx is a number.
If you download that file and read it you'll get alot of help
on C.

Microsoft asks me where I want to go today but UNIX gets me there.
