doubt

My program is running properly if I use the "F7" option in turbo C compiler and execute the code step wise.
But when I use the "RUN" option of turbo C compiler, it keeps running for ever.

Why does such a thing happen?

It would appear to me, given the code you posted nicely within [code][/code] tags, that the problem is on line 42.

I thought the solution was on line 42. Woah, wait a second! I think you're on to something. The answer lies in the problem. The meaning of both the problem and solution in the same line. This getting deep. I think we need to move this thread to the "C Philosophy" forum.


Quzah.

sorry, i thought this would be a common problem,
anyway here is the code.

And please tell me, if possible, if i can improve the code with any other special library functions!

Thanks
