Stock Profit
The Profit from the sale of a stock can be calculated as follows:
Profit = ((NS * SP)-SC)-((NS * PP) + PC)
where NS is the number of shares, SP is the sale price per share, SC is the sale commis-
sion paid, PP is the purchase price per share, and PC is the purchase commission paid.
If the calculation yields a positive value, then the sale of the stock resulted in a profit.
If the calculation yields a negative number, then the sale resulted in a loss.
Write a function that accepts as arguments the number of shares, the purchase price
per share, the purchase commission paid, the sale price per share, and the sale com-
mission paid. The function should return the profit (or loss) from the sale of stock.
Demonstrate the function in a program that asks the user to enter the necessary data
and displays the amount of the profit or loss.
