Introduction

Write C# Program to count total number of notes in entered amount. I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..

public class csharpExercise
{
    static void Main(string[] args)
    {
 
        int amount;
 
        int note1, note2, note5, note10, note20, note50, note100, note500;
 
        note1 = note2 = note5 = note10 = note20 = note50 = note100 = note500 = 0;
 
        Console.WriteLine("Enter amount: ");
        amount = Convert.ToInt32(Console.ReadLine());        
 
        if (amount >= 500)
        {
            note500 = amount / 500;
            amount -= note500 * 500;
        }
        if (amount >= 100)
        {
            note100 = amount / 100;
            amount -= note100 * 100;
        }
        if (amount >= 50)
        {
            note50 = amount / 50;
            amount -= note50 * 50;
        }
        if (amount >= 20)
        {
            note20 = amount / 20;
            amount -= note20 * 20;
        }
        if (amount >= 10)
        {
            note10 = amount / 10;
            amount -= note10 * 10;
        }
        if (amount >= 5)
        {
            note5 = amount / 5;
            amount -= note5 * 5;
        }
        if (amount >= 2)
        {
            note2 = amount / 2;
            amount -= note2 * 2;
        }
        if (amount >= 1)
        {
            note1 = amount;
        }
 
        Console.WriteLine("Total number of notes = \n");
        Console.WriteLine("500 = "+ note500);
        Console.WriteLine("100 = "+ note100);
        Console.WriteLine("50 = "+ note50);
        Console.WriteLine("20 = "+ note20);
        Console.WriteLine("10 = "+ note10);
        Console.WriteLine("5 = "+ note5);
        Console.WriteLine("2 = "+ note2);
        Console.WriteLine("1 = "+ note1);
 
        Console.ReadLine();
    }
}

Result
