Question

Write a program named MakeChange that calculates and displays the conversion of an entered number of dollars into currency denominations—twenties, tens, fives, and ones.

For example, if 113 dollars is entered, the output would be twenties: 5 tens: 1 fives: 0 ones: 3.

Answer in C#

(P.S i'm posting the incomplete code that i have so far below.)

using System;
using static System.Console;
class MakeChange
{
static void Main()
{
int twenties, tens, fives, ones;
WriteLine("Enter the number of dollars:");
int dollars = Convert.ToInt32(ReadLine());
twenties = dollars / 20;
dollars = dollars % 20;
tens = dollars / 10;
dollars = dollars % 10;
fives = dollars / 5;
dollars = dollars % 5;
ones = dollars / 1;
WriteLine("twenties:"+ twenties);
WriteLine("tens:"+ tens);
WriteLine("fives:"+ fives);
WriteLine("ones:"+ ones);
}
}

Answer 1

CORRECTED C# CODE:

using System;

class MakeChange
{
   static void Main()
   {
       //variable to stores the denominations
       int twenties, tens, fives, ones;
      
       //getting the user input
       Console.WriteLine("Enter the number of dollars:");
       int dollars = Convert.ToInt32(Console.ReadLine());

       // calculating the number of twenties
       twenties = dollars / 20;
       dollars = dollars % 20;

       // calculating the number of tens
       tens = dollars / 10;
       dollars = dollars % 10;

       // calculating the number of fives
       fives = dollars / 5;
       dollars = dollars % 5;

       // calculating the number of ones
       ones = dollars / 1;

       //displaying the denominations
       Console.WriteLine("\ntwenties:"+ twenties);
       Console.WriteLine("tens:"+ tens);
       Console.WriteLine("fives:"+ fives);
       Console.WriteLine("ones:"+ ones);
   }
}
