Write a C program, named a2.c, to solve the following problem.
A company has 4 salespeople (1 to 4) who sell 5 different products (1 to 5). Every day the company maintains a CSV file for each product sold. A CSV file is a comma-separated values file. The CSV file contains the product, and the total dollar value of that product sold by each salesperson that day. An example CSV file has been provided with the assignment.
Write a program that will read all this information for a day’s sales and summarize the total sales by salesperson and by product. After processing all the information for the day, display the results in a tabular format, with each column representing a salesperson and each row representing a particular product. Gross total each row to get the total sales of each product. Gross total each column to get the total sales by salesperson. Your output should include these cross-totals to the right of the totaled rows and to the bottom of the totaled columns.
For the sample data provided with the assignment the output could look like this
Seller1 Seller2 Seller3 Seller4 Total
Product1 915 777 886 383 2961
Product2 492 386 335 793 2006
Product3 27 362 421 649 1459
Product4 926 763 59 690 2438
Product5 736 172 426 540 1874
Total 3096 2460 2127 3055 0
· You may assume that each line in the CSV file is not larger than a number of your choice, say no larger than 256.
· You may assume that there are no spaces or other special characters in the names of the salespeople or products.
· You may assume that the names of salespeople and products are not larger than a number of your choice, say no larger than 20.
· You can use character arrays. You do not need to dynamically allocate memory for this assignment.
