There are a gauge to let the player know he's on the right or wrong track, and will encourage or discourage him to keep going. Now that we have discussed these different phases in game-development, let us not develop a simple tic-tac-toe game. Now let us analyze different elements of the game design in the program that we're going to make.
It's a two player game, so we need two variables to store their names and run a loop to ask for the player to enter their move turn by turn. So we need another variable to store the turn to see which player is to enter the move. Here are the variables:. We need a function to handle the navigation to the boxes when the player presses arrow keys and hit the Enter button to enter his move in the box. We need another variable to track the current box the player is on at the movement.
An array to store the values entered by the player. So here are the variables:. Here in this function, char a[3][3] is the array that holds the moves. Another variable is required to count the number of turns. There are nine boxes in total however the number of turns maybe more than nine because if the player tries to enter his move into a box that's already taken, then the chance passes over to the other player.
We need a function to put the move into the box chosen by the player and we need to make sure that we don't overwrite the value in a box:. Now how would we know what character to put into the box? Well, this function is called by the navigate function mentioned above.
The putintobox function checks if the box is taken and enter the value in to the array that represents the boxes a[3][3] , and calls another function showbox char ch, int box to show the character on screen in the specified box.
We would need another variable to check if the player wants to quit the game so — int quit;. In order to interact with the user, many messages are displayed. Also the player is told if he won the game or if it's a draw. The program will also ask if the player wants to play again. So in our program, the messages would be:.
The logic of this program is to run a while loop that runs till a player wins, or all the boxes are filled up but no one won the game or if the user wants to quit. Now while the loop is running, the variable chance that tracks whose chance is it to enter the move is updated. A function will check what was the key what pressed by the user user can enter only up, down, left, right or enter key and moves the cursor to the specified box and enter the character assigned to the player into the array and displays that on the screen.
It also makes sure that no box is overwritten. It the user tries to overwrite the box, chance is passed on to the other player as a penalty to the player who entered the wrong move.
Now we have all the functions in place, we move on to the third step that talks about Presentation. The ASCII character used in this program to display the vertical line is and for horizontal line is For a cross -
