Money Dispenser print out least amount of bills possible

[mikewaz]

I need some help. I'm supposed to create a code of an atm machine that dispenses the least amount of bills.
I'm running into the problem where program not printing out $80 dollars in the least amount of bills. it just prints out $50.
i need it to print $50 and $20 and $10
Any help is much appreciated.

Think of your dispense problem a little differently. Take out the biggest denomination first, and be sure to keep track of what you take!

void dispense(int moneyEntered)
{
    int fifties(0), twenties(0), tens(0);
    //initially, we haven't dispensed any money, so we still
    //have the total money left to dispense
    int moneyLeftToDispense = moneyEntered;

    if(moneyLeftToDispense >= 50)
    {
        //take however many whole fifties you can
        fifties = moneyLeftToDispense / 50;

        //after this, the remainder (% operator) is what is left
        //to dispense with the other bills
        moneyLeftToDispense = (moneyLeftToDispense % 50);
    }

    if(moneyLeftToDispense >= 20)
    {
        twenties = moneyLeftToDispense / 20;
        moneyLeftToDispense = (moneyLeftToDispense % 20);
    }

    if(moneyLeftToDispense >= 10)
    {
        tens = moneyLeftToDispense / 10;
        moneyLeftToDispense = (moneyLeftToDispense % 10);
    }

    if(moneyLeftToDispense > 0)
    {
        std::cout << "Whoops! Must not have entered a multiple of ten.\n";
    }
    
    std::cout << fifties << " x $50\n";
    std::cout << twenties << " x $20\n";
    std::cout << tens << " x $10\n";
}
