Following are the code of C# to prints the number of quarters, dimes, nickels, and pennies
Program Explanation:
- Declaration of the namespace.
- Made a class named "Class1".
- Declared the methods as well as the attributes.
- Declared the main method.
- Wrote the statements according to the given query.
Program:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Project1
{
class Class1
{
static void Main(string[] args)
{
int change = 0;
int quart, dim, nic, pen;
Console.WriteLine("enter amount of cents (less than 99)");
change = int.Parse(Console.ReadLine());
quart = change / 25; //calculate the remainder
int p = change % 25;
dim = (p / 10);
int a = p % 10;
// Nickles
nic = a / 5;
int c = a % 5;
pen = c;
Console.Write("There are {0} quarters.\n", quart);
Console.Write("There are {0} dimes.\n", dim);
Console.Write("There are {0} nickels.\n", nic);
Console.Write("There are {0} pennies.\n", pen);
Console.ReadLine();
}
}
}
