It's executing, it's just closing right away and not doing anything. Look at your main:

int main() {
int number1,number2,number3;
char key;
key='y';   // you assign 'y' to key


while (key=='n') {  // and loop while key == 'n'
//...
}
}

Note that since key never is 'n' (you initialized it with 'y'), the loop will never run.

You probably meant to do while(key == 'y') ?

thanks a lot, i corrected it but it keeps giving error before getting the 3rd number...
