Need help asap

Welcome to the "Pie in the Sky" bakers. The customer wants to buy some combination of bakery items like any single item, or two items for example; cake and biscuits. Write a program that displays the following menu for the bakery items available to take order from the customer using IF and Switch case statements. C = Cake (Rs. 500) B= Biscuits (RS. 200) The program first asks to enter the no of categories of bakery items i.e. 1 or 2, then it asks to enter the choice i.e. 'C' for Cake, 'B' for Biscuits and then for quantity. If the customer asks for other than menu items, it shows a message of the unavailability of items on bakers. The program should finally display the total charges for the order. Example input/output data is given: PIE IN THE SKY BAKERS WELCOME PLEASE SELECT FROM THE FOLLOWING MENU - CAKE B - BISCUITS HOW MANY TYPES OF BAKERY ITEMS YOU NEED TO ORDER = 2 Enter first iten you want to order = B enter quantity = Enter second iten you want to order = C enter quantity = 2 you have ordered 31 Cakes Biscuits - 1000 - 600 TOTAL = 1600 Thank u have a nice day
