Write a C (NOT C++) program will read in the binary file and provide a user interface to allow for adding items, providing the number of items in a particular category and for listing the contents of the file by category to the screen.

The user interface (for the second program) will be: Select option (A-add item, N-number of items in category, L-list all items, X-exit pgmZZ): (If A is selected) Enter name of item to add: Enter price: Enter aisle: Enter category:

(If N is selected) Enter category to print: (And then print-) There are number of items in the Canned Goods category (If L is selected) (Print all items by category. For example? Canned Goods Corn, price: 89 cents, Aisle: 1 the item file and binary code are as follows:

grocery.txt

corn 89 3 C greenbeans 60 3 C groundbeef 430 17 M wholemilk 250 16 D cheese 150 16 D apples 50 1 P cabbage 100 1 P cherries 150 1 P cabbage 75 3 C hominy 45 3 C filetmignon 900 17 M chicken 450 17 M halfandhalf 250 16 D sourcream 150 16 D grapes 100 1 P corn 50 1 P watermelon 200 1 P peas 89 3 C porkchops 200 17 P creamcheese 150 16 D
