Runtime library error

Hello:

When I run the attached program, a window with error pops up:

Debug assertion failed:

Program: c:/Windows/system32/MSVCP100.dll/
Line:734

I have no clue as to whats causing this error, anyone can give me a clue?

Thanks

And what's missing here?

oh those couts shouldnt be there, its defaulted to 16 and 16, it is meant to control how big the file is
