can you put loops inside of loops?

CRBottini (26)
Coding for a simulation of a convenience store for a school assignment. Need a case in the switch statement to repeat itself until the right amount is paid. Right now it repeats once, then goes back to the opening store choices. Don't know how to stop this.

I need the case below to repeat until the right amount is paid is it possible to put a loop inside of a loop?

Of course you can put a loop inside a loop...Your indentation is...not that good though so I can't really tell what you are trying to add/fix.

Ok say I am checking out of the store, and I enter an amount higher than what is owed.

ut << " THATS TOO MUCH, YOU ONLY OWE ME " << moneyOwed << " PENNIES" << endl;
        cout << "Enter Amount to pay..." << endl;
            moneyPaid = reader.readInt();


above will print. Then I enter another amount and it immediately returns to the beginning part

        cout << "               3. Toilet Paper.....................300 Pennies" << endl;

        cout << "MAKE YOUR SELECTION" << endl << endl;
           customerChoice = reader.readInt();


Need the inputs to repeat until the right amount is payed.

That's because after you leave the if/else if chain there you hit the break, jumping you out of your switch/case, and then because of your do while loop you go back to the start. You would need to put in another loop around the part you want to pay.
