Tic Tac Toe is a classical well known
interesting game which can be played between two persons at once.
How this application works ?
- 9 buttons are available in the game area, as shown in above image. An image control is also available behind each button. As a player click on a button, it is hidden and an image appears (displays either cross (for player 1) or zero (for player 2)). A 2d-array of integer type is used to keep the information about each button pressed, i.e. each move either by player 1 or player 2.
A function checkresult() is called to calculate the result each time you press a button (if number of moves are greater then 4).
- Two buttons (1. Reset 2. Exit) and one label controls are also present in application interface.
Reset - Resets the properties of controls, reassign values to variables, etc. to play the game again and to avoid the close and reopen of application to play.
Exit - To quit the game.
Label - It is used to display the result of the game.
As you can see in above image, 8 rectangles are
used to display all possible wins. You can see only one rectangle as a player
wins and these rectangles are hidden at the time of application startup.
