HELP!!

[mymsong]

i have this code that gets a number of car objects and i am stuck in some sort of loop at the line which i put on bold. when i finish initializing my first object, it's suppose to go back to the menu and prompt the user but instead it goes into an uncontrolled loop for about 20 times (oddly) and then stops at the menu
