Write a program to help a local restaurant automate its breakfast billing system. The
program should do the following:
 Show the customer the different breakfast items offered by the restaurant.
 Allow the customer to select more than one item from the menu.
 Calculate and print the bill.
Assume that the restaurant offers the following breakfast items (the price of each item is shown
to the right of the item):
Plain Egg RS 15.00
Omelet RS 15.00
Paratha RS 12.00
French Toast RS 20.99
Fruit Basket RS 120.49
Coffee RS 50.00
Tea RS 20.00
Use an array, menuList, of the struct menuItemType, as defined in Programming Exercise 2. Your
program must contain at least the following functions:
 Function getData: This function loads the data into the array menuList.
 Function showMenu: This function shows the different items offered by the restaurant and
tells the user how to select the items.
 Function printCheck: This function calculates and prints the check.
(Note that the billing amount should include a 17% tax.)
A sample output is:
Welcome to Café international
1 Plain Egg RS 15.00
2 Paratha RS 24.00
1 Coffee RS 50.00
Tax RS 6.83

Amount due RS 95.83

Format your output with two decimal places. The name of each item in the output must be left
justified. You may assume that the user selects only one item of a particular type

it could be e. idk for sure
