Time To Code: Task V and VI

Time To Code: Task V and VI

Let’s implement the final part of the game!

We'll cover the following...

Finding the winner

Once the players start playing the game, it can end in a win for one player or a tie.

Remember: The win condition is three consecutive "X"s or "O"s horizontally, vertically, or diagonally.

We’ve already provided some code to check for the winner. Before we move to our task, let’s quickly go through the provided code:

Java
char temp = winner(game_board);
if(temp == 'x') {
	displayBoard(game_board);
	System.out.println("Player1 (x) has won!");
	return;
} 
else if(temp == 'o') {
	displayBoard(game_board);
	System.out.println("Player2 (o) has won!");
	return;
} 
else {
	//If it's a tie or not
	if(tie(game_board)) {
	  System.out.println("It's a tie!");
		return;
	} 
	else {
		//If player1 is true, make it false, and vice versa; this way, the players alternate each turn
		p1Turn = !p1Turn;
	}
}
