Question

Use menu based functionality and validation loops to create a new customer bonus fruit package application for the Dirt to Dish discount produce company.

The program you create will prompt the user to enter a number to select one of three bonus pack options:

1 for Apple pack
2 for Orange pack
3 for Banana pack

**Use input validation to ensure a valid option has been selected before proceeding.

Use variables to keep track of how many of each fruit a customer will have depending on which bonus pack has been chosen. The amount of fruit per bonus pack is given as follows:

Banana pack: 5 bananas, 2 apples, 2 oranges
Orange pack: 5 oranges, 2 apples, 2 bananas
Apple pack: 5 apples, 2 bananas, 2 oranges

Use menu based functionality and input validation and prompt the user to choose from one of the following recipes:

1. Fruit medley (2 of each fruit)
2. Mixed Apple Pie (3 apples, 1 orange, 1 banana)
3. Banana tower (4 bananas, 2 oranges)
The amount of fruit required for each recipe is shown in parenthesis.

After a valid recipe choice has been made, subtract the amount of fruit needed for the recipe if the customer has enough fruit. If the customer does not have enough fruit then show a message telling the customer to buy more fruits.

Finally display the amount of fruit remaining from the bonus pack after the recipe selection has been made.

First example run:

This is Dirt to Dish's new customer bonus service!
Please select your free fruit package:
1. Apple pack
2. Orange pack
3. Banana pack
Please enter 1, 2, or 3: 2
You have chosen: Orange pack

You have a total of:
2 apples 5 oranges 2 bananas
Which dish would you like to make first?
1. Fruit medley (2 of each fruit)
2. Mixed Apple Pie (3apples, 1 orange, 1 banana
3. Banana tower (4 bananas, 2 oranges
Please enter 1, 2, or 3: 2
Mixed Apple Pie chosen
Sorry, you need more fruits!
The fruit you have left is:
2 apples
5 oranges
2 bananas

Thank you!
