I need help with a life counter ending the game. I need it to end the program when the lives hit 0

You already have a function that’s checking for this situation.

But this function is never called. As a first step, call this function when the lives counter changes.

Then change the function so that, instead of causeing the Game Over screen to happen, it causes the program to end. You can do that by having live_manager() call the exit() function instead of setting gameOver to ture.
