Hello All,
I'm experience an error that I am completely unfamiliar with. If someone
can help me, please do so. I've listed the error lines and the compile log
directly below...and for the really brave, I've placed the whole program at
the bottom.
Line 19: enum Choices { TEXTFILE = 1, UPDATE, NEW, DELETE, END };
*
*
Line 41: while ( ( choice = enterChoice() ) != END )
