C语言实现简单的三子棋小程序

1 game.h中用于函数定义

#ifndef __GAME_H__
#define __GAME_H__

#include <string.h>
#include <stdlib.h>
#include <time.h>
#include <stdio.h>

#define ROW 6
#define COL 6

void InitBoard(char board[ROW][COL], int row, int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col);
void Computermove(char board[ROW][COL], int row, int col);
char IsWin(char board[ROW][COL], int row, int col);
#endif //__GAME_H__

2.game.c实现游戏的函数

}
}
}
void DisplayBoard(char board[ROW][COL], int row, int col)  //打印显示棋盘
{
/*int i=0;
for(i=0;i<row;i++)
{
printf(" %c | %c | %c \n",board[i][0],board[i][1],board[i][2]);
if(i<(row-1))
{
printf("---|---|---\n");
}
}*/

}
}
void PlayerMove(char board[ROW][COL], int row, int col)   //玩家走的函数

static int  is_full(char board[ROW][COL], int row, int col)

3.test.c用来存放主函数

#define _CRT_SECURE_NO_WARNINGS
#include "game.h"
void menu()  //打印菜单
{
printf("*****************************\n");

printf("*****************************\n");

printf("*****************************\n");
}
void game()
{
char win = 0;

char board[ROW][COL] = { 0 };
InitBoard(board, ROW, COL);
DisplayBoard(board, ROW, COL);
printf("1 玩家先走   2 电脑先走   0 退出游戏\n");
scanf("%d", &c);
switch (c)

PlayerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);

}
}
void test()
{

srand((unsigned int)time(NULL));
do{
menu();
printf("请选择：");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;

}
} while (input);
