Initialize the Board

What we have

We have the breakdown of the game, so let’s go through the first thing we saw in the game.

We have to initialize a board for our game. A Tic-Tac-Toe board has 9 empty places, so we need an array of the same length.

Requirements of this module

We need to place X and O on our game board. These are char type inputs, so our array will be char type.

Now, we know that we need a char type array of length 9. We can perform these steps to complete this task:

• Receive two parameters: board and its size.

• Fill the array using the for loop with the characters “1” to “9”.

Let’s try it

All the functions are already defined. You just have to implement the given function and execute the code.
