Text Counting Program, No Errors, Doesn't Work

[TheMouseRan]

I'm using Visual Studio. No Errors are declared, but this will not display any of my menu. I think it is because the while(inputfile) meant to measure the integer values and count them is in some kind of loop.

What do!?

Regards,
John

I do not know how to attach text files on this forum. I keep the text file in the inner folder of visual studio with my program. It is entitled random.txt. Here is its contents:
