Requirement
Tic-tac-toe is a two-player game that children often play to pass the time. The game is usually played using a 3-by-3 game board. Each player chooses a symbol to play with (usually an X or an O) and the goal is to be the first player to place 3 of their symbols in a straight line on the game board (either across a row on the board, down a column or along one of the two main diagonals).
In this Assignment, you are to complete some functions that make up part of a larger program for playing tic-tac-toe. In the program, game boards are not restricted to being 3-by-3, but are instead N-by-N, where N is one of the integers from 1 through 9, inclusive. Our game boards will always be square. When you have completed your functions for this Assignment, you will be able to play games of tic-tac-toe on your computer!
