Struct coinbox, make change for input

I need help in writing the function that makes change for an input number. Input a bunch of quarters, dimes, nickels, pennies, then in MAKE_CHANGE the amount per say (184) is input. So for 184cents, runs through quarters first using the quarters we have in the coinbox, and then goes to the next currency for the remaining 9cents(184/25=7 184%25=9).

I may have worded it super weirdly, I apologize. I understand what needs to happen, im just having trouble writing it
