Use a double-subscripted array to solve the following problem. A company has four salespeople ( 1 to 4) who sell five different products ( 1 to 5). Once a day, each salesperson passes in a slip for each different type of product sold. Each slip contains:

a) The salesperson number
b) The product number
c) The total dollar value of that product sold that day

Assume that the information from all the slips for a day is available. Write a C program (2D array) that will read all this information for the day and store in a double-subscripted array sales. For each product find and display the total sales.
