/*Problem 7 : Write a C++ program to process the sales activity for 20 salesman. Each salesman deals in separate product and is assigned an annual target. At the end of the month, his monthly sales is added into the salestilldate. At the end of the year, his commission is calculated as follows: if sales made is more than target then the commission is 25% of the extra sales made +10 % of the target if sales made is equal to the target then the commission is 10% of the target. Otherwise commission is zero.
