What is the value of user2 when your program tries to enter the loop?
beginning (31)
before the second loop you should give a value to the user2 param.
heymrjack10 (18)
what you mean i gave the user2 a value of 0 before the loop and i ask the user if he wants to play again if he enters y or Y it re-enters the loop again those 5 rand generated problems.. if enter n or N it exits the program.

I might be really tired but the do-while loops does not look right..

it is:
do
{
do.stuff.in.here
}while(answer != 3)

The end part of the code is not even in a loop. You ask the person if he/she want to go again, and that's that. There is no loop there.

do
{
question
}while(answer != 'n')

Can be wrong, reeaall tired ^^

If user2 has the value 0 before the loop then it won't be equal to 'y' or 'Y' will it? Therefore it will never enter the loop.
