It's hard to see the logic flow of your program because of the way this website has caused your pasted source code to wrap around. I would have suggested ways to add the condition in a loop control (such as 'for' or 'while'), if I could tell exactly what your program is doing (it's difficult to read) but in the meantime you could use 'break' instead of 'goto'.
By the way, if you are trying to write Standard C++ then you don't need process.h, iostream.h should be <iostream> and main returns int, not void. You only need to use the .h headers if you are using a very old (i.e. from the mid-90s) compiler.
