Classes Practice

Spend some time practicing class concepts, including constructors. Note that the purpose of this practice is to aid in final project preparations!

Restaurant Class Redux

Look back at the restaurant challenge from the previous session, and try to build on it. Include a constructor for the Restaurant class, and work on creating a full-fledged console app to track restaurant reviews or restaurant ordering.

Fruit Stand: Bug Extermination

Visit the Fruit Stand Repl project, and try to fix the bugs in it. Some of these bugs may not be immediately obvious: try testing out the programs to discover them. Make sure that everything functions properly by the end!

There should be a total of 6 bugs to find and fix, across both the main.cs file and the Fruit.cs file.

HINT: Use the errors to guide the debugging process. Each error should point to the line number on which it occurs; start by finding the line, and then try to figure out what's wrong with it!

Fruit Stand: Enhancements

Once all of the bugs have been removed from the fruit stand, try adding the following enhancements!

Add Another Fruit to the Inventory

Create another Fruit object, and add it to the inventory List<Fruit>! One possible idea for another fruit would be grapes:

  \
 ()()
()()()
 ()()
  ()

Feel free to add any other fruit as well. Notice that all that is required is to create the new Fruit object and add it to the inventory list; the rest will take care of itself!

Add a Sugar Field

In addition to tracking the name, image, price, and calorie count for a Fruit, track the total grams of sugar it contains.

1. Update the Fruit class so that it contains a new int field: Sugar
2. Update the Fruit constructor so that it takes in a new int parameter for the sugar, and sets the field value
3. Update the Display method on the Fruit class so that it includes the total grams of sugar for the fruit
4. Update each new Fruit object created so that they all pass in a value for the Sugar field

Refactor the Program: ShoppingCart Class

Currently, a lot of the code for the program lives in the main.cs file. This can become a little unwieldy. Try to refactor the program so that there is a new class, ShoppingCart, that handles a lot of the functionality.

The ShoppingCart class should contain:

• A List<Fruit> for the inventory of the fruit stand
• A List<Fruit> for the current items in the cart

The ShoppingCart should be able to:

• Calculate the total price for the cart
• Calculate the total calories for the cart
• Get the count for a given item in the cart
• Print out the contents of the cart, including total price and calories

By the end of the refactoring, the main.cs file should not contain any methods other than the Main method. This separation of concerns will make the program much easier to maintain in the future.
