Hi I am trying too create code that takes an amount like 1.35 and counts the minimum amount of coins needed to make change just out of coins, 5 quarters, and 1 dime.
but my code has some interesting errors
example 1.35 shows correct at 5 quarters and 1 dime BUT if it's under a dollar like .35 it shows 1 quarter, 1 nickle, and 4 pennies.
Can someone tell me where my math goes wrong in the following block of code:
#include <iostream>
using namespace std;
//converts dollars into minimum amount of coins. ie input dollar and 22 it will calculate 4 quarters two dimes and two pennies,
const double QUARTER = .25;
const double DIME = .10;
const double NICKLE = .05;
const double PENNY = .01;
int main()
{
double numberOfQ, numberOfD, numberOfN, numberOfP;
double total;
cout << "Please input total amount of money: " << endl;
cin >> total;
//while (total > 0) {
if (total >= .25) {
numberOfQ = (int)(total / QUARTER);
total = total - numberOfQ * QUARTER;
cout << "Number of Quarters: " << numberOfQ << endl;
cout << "total :" << total << endl;
}
if (total < 0.25 && total >= 0.10) {
cout << "total before:" << total << endl;
numberOfD = (int)(total / DIME);
total = total - numberOfD * DIME;
cout << "Number of Dimes: " << numberOfD << endl;
cout << "total :" << total << endl;
}
if (total < 0.1 && total >= 0.05) {
cout << "total before:" << total << endl;
numberOfN = (int)(total / NICKLE);
total = total - numberOfN * NICKLE;
cout << "Number of Nickles: " << numberOfN << endl;
cout << "total :" << total << endl;
}
if (total < 0.05 && total > 0) {
cout << "total before:" << total << endl;
numberOfP = (int)(total / PENNY);
total = total - (numberOfP * PENNY);
cout << "Number of Pennies: " << numberOfP << endl;
cout << "total :" << total << endl;
}
//}
}
