Could you please elaborate more on what you're trying to do? What do you mean by 'code run not true'?

Also, is there a reason you're using printf and scanf instead of cout and cin? The latter two are C++ functions - the former are C.

Might consider formatting your code a little better for readability as well. Looks like the copy/paste didn't keep formatting.
