problem in quiz game

[hello1234567890]

Hi, i have written a quiz game on c++, the problem is that when i apply while loop to all the questions, the program does not pass question 1 and terminates, but when i apply while loop to question 1 only, then the question goes to the next question.

here is the program in which i have applied while loop to only question 1. can anyone apply loop to all the question or give me suggestions how to make it run????

#include <iostream>
#include<conio.h>

1. Nearly every big forum has a "READ BEFORE YOU POST!!!" for a reason. Read this ( http://www.cplusplus.com/forum/beginner/1/ ) then edit your post, using code tags.

2. If the supplied code works then we can't help you. Give us the broken code, what error do you get if any? If not, what is the expected result vs what really happened?
