10. Objects

Feel free to use your laptop
You are strongly encourage to work with others
- When you get stuck, ask those sitting around you for help
- Get used to working together in the labs
- Peer teaching and peer learning has been empirically shown to be very effective

10.1. Pre Lab Exercises

Have a working implementation of the Circle class from lecture
- You can obtain the source code from here
- It will provide a nice template for all the classes you will make in this lab

10.2. Before Kattis

Create a Square class
- Single attribute side_length
- The constructor will take a parameter for specifying the size
- Method for calculating area()
- Method for calculating the perimeter()
- Make instances of the class and write assert tests to verify correctness
Create a Rectangle class
- Attribute for length
- Another attribute for width
- The constructor will take two parameters for specifying the size
- Method for calculating area()
- Method for calculating the perimeter()
- Make instances of the class and write assert tests to verify correctness
Create a RectangularPrism class
- Attributes for length, width, and height
- The constructor will take three parameters for specifying the size
- A method for calculating surface_area()
- A method for calculating volume()
- Make instances of the class and write assert tests to verify correctness

10.3. Kattis Problems

You should be using a scrap piece of paper to work out the ideas for the following problems
- The problems you are to solve are getting too complex to try to solve by just coding
- Trying to solve problems by just typing away will not yield success
