C language to realize the three chess game

（ One ): Pre writing ideas

1： First, we can create 2 Source file ,1 Head file ; Pictured

among game.c It is to realize game operation ;test.c It is to realize the logical planning of the game ;game.h Is the declaration of the record header file and its functions ;

（ Two ):test.c The realization of game logic

The code for initializing the chessboard and printing the chessboard is as follows ：

 

  At that time, I was realizing vertical and --- When printing , stay printf The corresponding coordinates are added to the statement , This will cause the compiler to fail to compile ;

And in use printf Be sure to add \n, I didn't add it at that time, but I misplaced the elements of the chessboard ;

  Note that variables cannot be put into while,do while And other compound statements ; Every time a player plays chess , After playing chess, the computer should use judgment sentences to judge , At this point, we can use the return value of the function to judge

Then we can construct a function to judge the success or failure of computers and players ;

Yes 4 In this case ;

1： Game player wins

2： Computers win ;

3： It ends in a draw ;

4： It's not over yet , Keep playing chess ;

Let's take a look at the relevant code ：

 

 

I wrote is_win Function used x,y I mistakenly think that this variable is related to other functions in this function, which leads to an error ; Print the chessboard in front , And its players only save the chess playing information ;

When judging the draw, we first traverse the chessboard ：

  Then use the return value of the function to judge whether it is a draw ;

Next, most of the code is completed ; Just print the menu ;

 game.h Game related statements   Finally , The game of three piece chess is finished ！
