Can someone tell me why this is not printing the correct score; it just exits out of the loop

Question

/*The program's purpose is to test the user's ability to correctly identify the mascots of four
universities. Users will be awarded one point for each correct response, one point will be
deducted for an incorrect response, and zero points will be deducted if the user responds "don't know." 
This means that your program will need to keep score as the user responds
to the prompts from the quiz and print that score to the console at the end of the program's
execution.*/

Answer 1

You use break operator in each if-else statment, because of your loop exited after:

if (x==1){
...
break;
}else if (x==2){
...
break;
}

Remove that, and your loop will work as you expect.

Answer 2

The problem is that you break out of your loop with break no matter what happens. The break instruction is executed in both cases (X==0 and X==1). SO remove this (if you want the question to try again) or replace it with a continue. That way the loop restarts and does not quit.

You could try this, Try this (not tested):
