.6 Currency (Weight: 4%)
Problem Specification
The problem concerns the conversion of currency from different countries and the commission the bank will charge for this. When converting currency, banks always charge a commission of a few percent or a fixed minimum commission – whichever is greater.
Write a program to input data required to convert from another currency to Pounds. Also charge commission according to the method below.
NOTE: 3 points are awarded for the program, an additional one for presenting a correct flow chart of the program to your tutor.

Method
1. Prompt and read 4 input parameters in this order:
 Commission rate (e.g. 1.4 for 1.4 percent)
 Currency to convert from (this is a 3-letter code, e.g. JPY for Japanese Yen, EUR for Euros, USD for US Dollars, etc)
 Rate of exchange to Pence (e.g.: 0.014 for Euros  2.80 Euros / 0.014 = 100 Pence)
 Amount of foreign currency to exchange (e.g. 327.55)
2. Convert the foreign currency into Pence.
3. If the Pence sum arising from this conversion is less than or equal to the minimum commission (5 Pounds in this exercise), print the message "Amount too small!"
4. Now calculate the percentage commission. If this calculated percentage commission is less than the minimum commission, the payout will be the sterling amount (split into pounds and pence) minus the minimum commission.
5. If the calculated percentage commission is greater than or equal to the minimum commission, the payout is the sterling amount (split into pounds and pence) minus the calculated commission.


Hints
The above Method can be written in Pseudo Code as shown below. This should help you to develop the flow chart:

START OF PROGRAM 
	Set constant MIN_COMM to 500 (minimum commission is 500 pence) 
	PROMPT and READ the 4 input parameters (in the correct order!) 
	Calculate the amount in pence (penceAmount = foreignAmount / exRate;) 
	IF penceAmount < MIN_COMM 
		PRINT "Amount too small"
	ELSE 
		Calculate perc. commission (comm = penceAmount * commRate /100;) 
		IF commision less than MIN_COMM 
			commission=MIN_COMM 
		END IF  
		Split commission into Pounds and Pence 
		PRINT commission Pounds and Pence  
		actPayOut = penceAmount – commission
		Split actPayOut into Pounds and Pence 
		PRINT actPayOut Pounds and Pence 
	END IF 
END OF PROGRAM
