Tic-Tac-Toe MATH 210-01, Fall 2021 Ryan Pellico, Department of Mathematics, Trinity College The function tictactoe.m allows you to play a game of Tic-Tac-Toe using MATLAB’s input() function to ask the user for moves, and basic plotting tools to draw X’s and O’s in the corresponding space, producing a figure like the on in the left below. 1. (30 points) Make the game “look nice", similar to the figure above on the right. Choose colors for each part of the game, make sure the aspect ratio is set so the board looks like a square, remove axis labels, etc. 2. (10 points) Instead of using the mod() function on line 32, write an if statement that switches the variable whose_move back and forth between player 1 and 2 as discussed in class. Do 3 of the following 4 for (20 points) each. 3. Write a function did_someone_win() that takes in the variable board and outputs a boolean variable oneORzero depending on if someone has won. 4. Incorporate the function did_someone_win() into the function tictactoe.m to stop the game as soon as someone wins. Use the text.m function to display a message on the game board that the appropriate player won. 5. Write a function valid_move() that takes in the variables board and input_move and outputs a boolean variable oneORzero depending on whether the most recent move is allowed. 6. Incorporate the function valid_move() into the function tictactoe.m to keep prompting the current player in the command line until a valid move is given.
