Question

Instructions Write a program called stocks.cpp. The program should prompt the user for the number of shares purchased, purchase price per share, the commission for the purchase, sale commission paid, and the price the shares were sold at. The program should validate each of these values to ensure they are acceptable (none of these values can be less than zero) and should then pass them to a function called calculateProfit. The function should use the following formula to determine the profit: Profit = ((NS *SP) - SC)-((NS * PP) + PC) Where NS is the number of shares, SP is the sale price, SC is the sale commission, PP is the purchase price, and PC is the purchase commission. You should also write functions for each of the values you need to take in from the user. Each function should take in a value from the user, validate it, and once the value is valid, return it back to the main. The main should then call calculate Profit to compute the result.

Enter number of shares purchased :: 154 Enter sale commision on shares :: 12 Enter sale price of shares :: 120 Enter purchase price of shares :: 100 Enter purchase commision on shares :: 10 total profit is :: 3058

Enter number of shares purchased :: -2 Invalid value !!! Enter number of shares purchased :: 154 Enter sale commision on shares :: 12 Enter sale price of shares :: -5 Invalid value !!! Enter sale price of shares :: 120 Enter purchase price of shares :: 100 Enter purchase commision on shares :: 10 total profit is :: 3058
