Three products are sold by a company. Write a program that inputs the name of each product and its corresponding revenue and cost. After calling a calculateProfit$()$ function for all three products, have the main function determine and display which product was the most profitable and how much profit it generated. The calculateProfit$()$ function should be passed the revenue and cost of each product as arguments and should calculate the profit obtained by each product. You will be calling calculateProfit$()$ only once, but the function should provide the three profit values all at once to the main program.

This program takes the revenue and cost of three products as input, calculates the profit for each product in a single function call to calculateProfit$()$ and sends all three profits to the main program, and then determines the most profitable product using a function and displays the most profitable product in the main program. Please follow the instructions and meet the requirements to the letter.
