Include a program that asks for purchase price, value added tax (in ISK) and sales price in kr.
The program should be two-fold.
The former case finds out what the store gets for the product. The case must be included in the sales price, the purchase price and the value added tax (in krónur). It will then return the proceeds
How we calculate the proceeds: Profit = (Sales price - (Purchase Price + VAT))
The latter case finds the difference between the purchase price and the selling price. If the difference is negative (in minus) the text prints: Here something went wrong.
Otherwise, write the text: The difference between the purchase price and the selling price is: difference.
