Write a program (with c only) to implement a simple currency converter program. Commands are as follows:

Euro-US

US-Euro

Euro-Pound

Pound-Euro

Pound-US

US-Pound

showrates

quit

Note that the commands are EXACTLY as shown. Capital letters and lower case letters as shown. There is a very good reason for this requirement, as will become clear later in the semester.

Commands work as follows:

Euro-US

requests a currency amount in Euros

converts that into a currency amount in $US.

US-Euro

reverse the above; request an amount in $US, convert it into Euros

Euro-Pound, Pound-Euro

same thing for converting Pound Sterling to Euros and vice versa

Pound-US, US-Pound

same thing for converting Pound Sterling to $US and vice versa

showrates

shows the exchange rates used in an appropriate way

quit

exit the program

Use the following currency exchange rates (taken from Monday, August 26, 2013)

$1.0000 US = 0.74759 Euro

$1.0000 US = 0.64173 Pound Sterling
