Write a c# program that converts currencies between british currency of pounds andpence, in which 1 pound contains 100 pence, and u. s. currency in dollars and cents. assume an exchange rate of 1.6595 u. s. dollars per british pound. give the user a menuto choose the type of conversion. allow the user to repeat as often as desired. (see testyour understanding questions 39 and 41.)

Here's program. Add your own rate below, I've added commentary where. Try it: 
double amount;  
string currency;
Dictionary<string, double> factors = new Dictionary<string, double>(); factors.Add("GBP", 1.1111D);
factors.Add("USD", 1.11111D); // here you can add the rate you need 
Console.WriteLine("Please enter the amount of Euro you wish to be converted:");
        amount = double.Parse(Console.ReadLine());
Console.WriteLine("");
Console.WriteLine("Please choose the currency you wish to convert to:"); Console.WriteLine("USD");
Console.WriteLine("GBP"); Console.WriteLine("");
        currency = Console.ReadLine();
double factor;
if (factors.TryGetValue(currency, out factor))
{
Console.WriteLine("You have entered {0} EUR which converts to {1} {2}", amount, amount * factor, currency);
}
else
{
Console.WriteLine("You did not enter a recognised currency {1}", currency);
}

The answer should be b.
