Realization of Three-Mixed Chess with C Language

To realize the man-machine game of sanbang, the file composition is in the form of header file and source file, as follows:
The declaration of the function put into the game.h file, the macro definition used, and the inclusion of the header file.
game.c In the file is the implementation of each part of the function. The
test.c file is the test function, and the main logic implemented by the whole program is placed.
The code of each part is as follows:

game.h

#ifndef     __GANE_H__
#define     __GANE_H__          // 头文件组合形式

#define    ROWS  3              //行数
#define    COLS  3              //列数

#include <stdio.h>              //所用的头文件
#include <stdlib.h> 
#include <time.h>
#include<string.h>


void print_board (char board[ROWS][COLS],int rows,int cols );//打印表格函数

void init_board (char board[ROWS][COLS],int rows,int cols ); //初始化函数

void player_move (char board[ROWS][COLS],int rows,int cols); //玩家移动函数

void computer_move (char board[ROWS][COLS],int rows,int cols); //电脑移动函数

char f_win(char board[ROWS][COLS],int rows,int cols);           //检验函数


#endif      //__GANE_H__
