I don't what to use to get the least number of bills. Should I use a loop, if statement? CODE #include <iostream> using namespace std; int dispense(int amount, int ten, int twenty, int fifty); int main() { int amt; int tens; int twenties; int fifties; cout << "Enter the amount desired (must be a multiple of 10 dollars) : "; cin >> amt; dispense(amt, &tens, &twenties, &fifties); cout << "Number of fifties : " << fifties << "\n"; cout << "Number of twenties : " << twenties << "\n"; cout << "Number of Tens : " << tens << "\n"; return 0; } int dispense(int amount, int ten, int twenty, int fifty) { fifty = amount/50; twenty = amount/ 20; *ten = amount/10; }

Same again for each bill required. new_amount = amount - ( 50 * number of fifties ) jeronimo0d0a's method is better if the known amounts are small.

Kind of like this:

cpp

#include <iostream>

using namespace std;

int process(int cash)
{
 int num,tens,twenties,fifties=0;
  while (cash>=50){
       fifties++;
       cash=cash-50;
       }
  cout << "You used "<<fifties<<" $50.00 bills"<<endl;
  twenties=0;
  while (cash>=20){
       twenties++;
       cash=cash-20;
       }
  cout << "You used "<<twenties<<" $20.00 bills"<<endl;
  tens=0;
  while (cash>=10){
       tens++;
       cash=cash-10;
       }
     num=fifties+twenties+tens;  
  cout << "You used "<<tens<<" $10.00 bills"<<endl;     
  return (num);
  }
  
  
int main(){
   int amt;
   int d;
   cout << "Enter the amount desired (must be a multiple of 10 dollars) : ";
   cin >> amt;
   cout <<"You have entered $"<<amt<<".00"<<endl;
   d=process(amt);
   cout << "You need a  minimum of "<< d <<" bills."<<endl; 
system ("PAUSE");
}
