Tic tac toe

This a problem set for you to work through

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

1. to build your skill applying computational thinking to a problem
2. to assess your knowledge and skills of different programming practices

What is this problem set trying to do

This problem set is testing your computational thinking, your skill and understanding of lists, and your skill and understanding of loops

The Problem

Your program must do three things:

1. it must allow a human to play against a computer a game of tic tac toe
   1. your program must have win and lose conditions
2. it must draw a tic tac to board, updated with x's and O's as the computer and human play.
3. It must follow the rules of tic tac toe

Hacker edition

In the hacker version:

• Your program should be good at playing tic tac toe

• To what extent is your code free of bugs?

Design

• To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
• To what extent is your code eliminating repetition?
• To what extent is your code using functions appropriately?

Style

• To what extent is your code readable?
• To what extent is your code commented?
• To what extent are your variables well named?
• To what extent do you adhere to style guide?

Represent by means of a labelled, accurate diagram or graph, using a pencil. A ruler (straight edge) should be used for straight lines. Diagrams should be drawn to scale. Graphs should have points correctly plotted (if appropriate) and joined in a straight line or smooth curve.

Consider the merits or otherwise of an argument or concept. Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument.

Produce a plan, simulation or model.
