rewrite the code above (Breakfast billing system) using class.

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                                 $1.45

Bacon and Egg                         $2.45

Muffin                                     $0.99

French Toast                           $1.99

Fruit Basket                             $2.49

Cereal                                      $0.69

Coffee                                      $0.50

Tea                                          $0.75

Use an array, menuList, of the struct menuItemType, with three components: menuItem of string, menuPrice of type double, and Count of type int. Your program must contain at least the following functions:

Function getData: This function loads the data from a file named menu.txt with the above breakfast items 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 5% tax.)

A sample output is:

Welcome to Johnny’s Restaurant

Bacon and Egg             1          $2.45

Muffin                         1          $0.99

Coffee                          2          $1.00

Amount Total                          $4.44

Tax                                          $0.22

Amount Due                            $4.66
