PROJECT 7 - TIC TAC TOE

Lab 3 Overview

Welcome to Lab 3 of our Connect Four project! In this session, we delve into the heart of programming design – breaking down our game into manageable parts and understanding how these parts communicate with each other. This approach not only simplifies our coding process but also makes our code more organised and easier to debug.

Breaking Down Connect Four

In our game, each function will handle a distinct aspect of the game. Often these functions will be related to the requirements you defined earlier.
For example, if we go back to our requirements and look at the top priority items we might define the first two functions of our game:

• InitialiseBoard - Sets up the 7x6 grid as a 2D list with empty values. Runs at start of game.

• DisplayBoard - Represents the current state of the board on the console screen as a grid. Runs at start of game and after each move.

Understanding Data Flow Between Functions

Data flow is how information moves through the program. Because we have divided our program into distinct functions we must pass data between them. Recall that functions may receive data in the form of arguments but also return data back.
For example:

• InitialiseBoard - Returns a 2D list

• DisplayBoard - Receives a 2D list
