I could be just frustrated, but for some reason after I added documentation to my program, it no longer works as it did before. I appreciate anybody taking the time to glance at it and point out what I'm sure is a totally obvious error. I am receiving 'member function redeclaration not allowed' (on my show num2 function) and 'missing function header' on my add function, as well as several related errors. I have attached my header, implementation, and main() (application) file. Thanks so much.
P.S. Knowing that there are umpteen ways to improve this program, unfortunately I procrastinated and no longer have time to make improvements.
