You are a fundraising distributor who needs to to pre-sell a limited number of doughnut coupon books. Each buyer can buy as many as 4 coupon books. No more than 100 coupon books can be sold. Implement a program called Fundraiser that prompts the user for the desired number of coupon books and then displays the number of remaining coupon books. Repeat until all coupon books have been sold, and then display the total number of buyers.
