C# – Quick Exchange Rate Calculator – Video

Posted on August 1, 2013 by

Hello All,

I have created a small video, showing how to make use of the do-while loop for creation of small console applications.

The interesting part of the code is the usage of the do-while loop, which executes the code until something different than “yes” is entered at the end. Pretty useful indeed!

Enjoy the code!

This is the code:

using System;
class Program
{
    static void Main()
    {
        int i = 1;
        float exchangeRate, euro, dollar;

        Console.WriteLine("Exchange Euro in Dollars");
        do
        {
            Console.Write("Exchange Rate:");
            exchangeRate = Convert.ToSingle(Console.ReadLine());
            Console.Write("Euro:");
            euro = Convert.ToSingle(Console.ReadLine());

            dollar= euro*exchangeRate;
            Console.WriteLine("You will get " + dollar.ToString("0.00 $"));
            Console.Write("Should we end the program? (yes/no)");
            string s = Console.ReadLine();
            i = string.Compare(s,"yes");
        } while (i!=0);
    }
}

using System;

class Program

{

static void Main()

{

int i = 1;

float exchangeRate, euro, dollar;

Console.WriteLine("Exchange Euro in Dollars");

{

Console.Write("Exchange Rate:");

exchangeRate = Convert.ToSingle(Console.ReadLine());

Console.Write("Euro:");

euro = Convert.ToSingle(Console.ReadLine());

dollar= euro*exchangeRate;

Console.WriteLine("You will get " + dollar.ToString("0.00 $"));

Console.Write("Should we end the program? (yes/no)");

string s = Console.ReadLine();

i = string.Compare(s,"yes");

} while (i!=0);

}

If you are interested in the way the program functions, you may find it here.

Have a nice day!
