Going back to loop

persades (34)
Hello everyone, I've managed to tackle my assignment and complete it with the exception of one requirement, this program must loop back to the first menu if the users choses not to kick everyone out of the bus once its reached max capacity(50) this should take them back to the main menu and give them the option to terminate the program. .. I've set it to 5 so it does not have to loop so many times for testing purposes

I'm thinking my loops are sloppy and a nested loop is the solution but I'm a bit stumped, I appreciate your input.

You could put the menu into a value returning function - when the condition is met call the function and return 0 on the proper input
