Can someone help me with this C++ program:

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. They should be able to specify the number of each individual item they want.

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

Here is a sample output:

Welcome to Johnny\'s Restaurant
1 Bacon and Egg    $2.45
2 Muffin            $1.98
1 Coffee            $0.50
Tax                 $0.25
Amount Due          $5.18

A data file is provided which has the menu item on a line followed by the price, followed by the next menu item, followed by its price, etc.

Turn in your source code which should be commented as follows:

Analysis at the top of the file

Function analysis, preconditions, and postconditions after each function prototype

Major tasks identified as comments in main function

Comments in functions as needed
