三子棋代码的实现需要一个简单的思路做指引，所以我们先来做一下思路的整理，代码的实现主要分为以下几个步骤：
1.初始化数组
2.显示数组
3.电脑走
4.玩家走
5.判断输赢
所以，先写出源文件game.h，如下。
#ifndef __GAME_H__
#define __GAME_H__
#define ROWS 3 //定义行
#define COLS 3 //定义列
//初始化数组
void init_board(char board[ROWS][COLS], int rows, int cols);
//显示数组
void display_board(char board[ROWS][COLS], int rows, int cols);
//电脑走
void computer_move(char board[ROWS][COLS], int rows, int cols);
//玩家走
void player_move(char board[ROWS][COLS], int rows, int cols);
//判断输赢
char check_win(char board[ROWS][COLS], int rows, int cols);
#endif//__GAME_H__接下来再写出主体的main函数，使这个三子棋的大体先做出来。以下为main.c函数。要实现的主要为选择界面以及大体的顺序。
#define _CRT_SECURE_NO_WARNINGS
#include"game.h"
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
void menu()
{
printf("*******************************\n");
printf("*****1.paly 2.exit *********\n");
printf("*******************************\n");
}
void game()
{
char ret = 0;
char board[ROWS][COLS] = { 0 };
init_board(board, ROWS, COLS);
while (1)
{
printf("电脑走：\n");
computer_move(board, ROWS, COLS);
display_board(board, ROWS, COLS);
ret = check_win(board, ROWS, COLS);
if (ret != 'q')
{
break;
}
printf("玩家走：\n");
player_move(board, ROWS, COLS);
display_board(board, ROWS, COLS);
ret = check_win(board, ROWS, COLS);
if (ret != 'q')
{
break;
}
}
if (ret == '*')
{
printf("玩家赢了！\n");
}
else if (ret == 'o')
{
printf("电脑赢了！\n");
}
else if (ret == ' ')
{
printf("平局！\n");
}
}
int main()
{
int input = 0;
srand((unsigned)time(NULL));
do
{
menu();
printf("请选择：");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 2:
return 0;
break;
default:
printf("输入错误，请重新输入！\n");
break;
}
} while (input);
system("pause");
return 0;
}以下为函数模块功能的的分布实现：
#define _CRT_SECURE_NO_WARNINGS
#include"game.h"
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
void init_board(char board[ROWS][COLS], int rows, int cols)
{
int i = 0;
int j = 0;
for (i = 0; i < rows; i++)
{
for (j = 0; j < cols; j++)
{
board[i][j] = ' ';
}
}
}
void display_board(char board[ROWS][COLS], int rows, int cols) //显示棋盘
{
int i = 0;
for (i = 0; i < rows; i++)
{
printf("| %c | %c | %c |\n", board[i][0], board[i][1], board[i][2]);
if (i <= rows - 1)
{
printf("|----|----|----|\n");
}
}
}
void computer_move(char board[ROWS][COLS], int rows, int cols) //电脑走
{
while (1)
{
int x = rand() % 3;
int y = rand() % 3;
if (board[x][y] != '*' && board[x][y] != 'o')
{
board[x][y] = 'o';
return;
}
}
}
void player_move(char board[ROWS][COLS], int rows, int cols) //玩家走
{
int x = 0;
int y = 0;
printf("玩家请输入位置，如:x y》");
do
{
scanf("%d %d", &x, &y);
if (board[x - 1][y - 1] == 'o')
{
printf("该位置已经被占用，请重新输入：》");
}
else if (((x - 1)>3) || ((y - 1)>3) || (x - 1 < 0) || (y - 1 < 0))
{
printf("输入位置错误，请重新输入：》");
}
else
{
board[x - 1][y - 1] = '*';
break;
}
} while (1);
}
static int is_full(char board[ROWS][COLS], int rows, int cols) //判断棋盘满没有
{
int i = 0;
int j = 0;
for (i = 0; i < rows; i++)
{
for (j = 0; j <cols; j++)
{
if (board[i][j] == ' ')
{
return 0;
}
}
}
return 1;
}
char check_win(char board[ROWS][COLS], int rows, int cols) //判断输赢
{
int k = 1;
int i = 0;
for (i = 0; i < rows; i++) //判断行
{
if ((board[i][0] == board[i][1]) && (board[i][1] == board[i][2]) && board[i][0] != ' ')
{
return board[i][0];
}
}
for (i = 0; i < cols; i++) //判断列
{
if ((board[0][i] == board[1][i]) && (board[1][i] == board[2][i]) && (board[0][i] != ' '))
{
return board[0][i];
}
}
if ((board[0][0] == board[1][1]) && (board[1][1] == board[2][2]) && (board[0][0] != ' ')) //判断正斜
{
return board[1][1];
}
if ((board[0][2] == board[1][1]) && (board[1][1] == board[2][0]) && (board[0][2] != ' ')) //判断反斜
{
return board[0][2];
}
if (is_full(board, rows, cols))
{
return ' ';
}
return 'q';
}以下为程序运行的三种结果：
