CAN ANYBODY CHECK MY C++ PROGRAM WHAT's wrong with it?
I don't know how you got your sample run because the code you posted have a lot of compilations errors.





I fixed them, but since some of the line of your code got cutted by YA I can't really check the result.





Anyway here it is :


#include "stdafx.h"


#include %26lt;iostream%26gt;

Reply:what is it doing or showing that tells you that something is wrong? are you getting a compiling error, runtime, or just an incorrect answer?
