实现简单三子棋游戏基本思路；
1.首先创建一个数组并且初始化棋盘（数组）；
void Initboard(char board[ROW][COL],int row,int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
board[i][j] = ' ';
}
}
}2.打印棋盘；
void Displayboard(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
{
printf("|");
}
}printf("\n");
for (j = 0; j < col; j++)
{
if (i < row - 1)
{
printf("---");
}
if (i == col-1)
{
break;
}
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
}
/*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");
}*/
}
3.电脑随机走一步；
void Computer_move(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑走:>\n");
while (1)
{
x = rand() % row; //产生随机值 0-row;
y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = 'o';
break;
}
}
}3.玩家走一步；
void Player_move(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("请输入坐标：>\n");
while (1)
{
scanf("%d%d", &x, &y);
if (x > 0 && x <= row &&y >0 && y <= col && board[x-1][y-1] == ' ')
{
board[x - 1][y - 1] = 'x';
break;
}
else
printf("请重新输入坐标：>\n");
}
}4.判断输赢；
char check_win(char board[ROW][COL], int row, int col)
{
int i;
//判断电脑和玩家走过后，是否已经连成了三个点的直线；
//如果有一条三个点连的直线，那么返回构成直线的符号；
//'0'电脑赢 'x'玩家赢；
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2])
{
return board[i][1];
}
}
for (i = 0; i <col; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i])
{
return board[1][i];
}
}
if (board[0][0] == board[1][1] && board[1][1] == board[2][2])
{
return board[1][1];
}
else
if (board[0][2] == board[1][1] && board[1][1] == board[2][0])
{
return board[1][1];
}
if (is_full(board, row, col))//用一个函数实现判断棋盘是否已满，来判断平局；
{
return 'q';//棋盘满了返回'q';
}
return 0;
}5.为了判断棋盘是否已经满了，编写一个is_full()函数；
int is_full(char board[ROW][COL], int row, int col)
{
int i, j;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
if (board[i][j] == ' ')
return 0;
}
}
return 1;
}以上便是基本思路，完整代码见下
1.所需要的头文件 game.h
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define ROW 3
#define COL 3
void Computer_move(char board[ROW][COL], int row,int col);
void Player_move(char board[ROW][COL],int row, int col);
char check_win(char borad[ROW][COL], int row,int col );2.测试代码， tese.c
#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"
void menu()
{
printf("**************************************\n");
printf("******* 1.play 0.exit **********\n");
printf("**************************************\n");
}
void game()
{
char ret = '0';
char board[ROW][COL] = { 0 };
Initboard(board, ROW, COL);
Displayboard(board, ROW, COL);
while (1)
{
Computer_move(board, ROW, COL);
ret = check_win(board, ROW, COL);
if (ret == 'o')
{
printf("电脑赢\n");
Displayboard(board, ROW, COL);
break;
}
else if (ret == 'q')
{
printf("平局\n");
Displayboard(board, ROW, COL);
break;
}
Displayboard(board, ROW, COL);
Player_move(board, ROW, COL);
ret = check_win(board, ROW, COL);
if (ret == 'x')
{
printf("人赢\n");
Displayboard(board, ROW, COL);
break;
}
Displayboard(board, ROW, COL);
}
}
int main()
{
//三子棋
//菜单
//选择 1/0
//游戏
int input = 0;
do
{
menu();
printf("请选择:>");
scanf("%d", &input);
srand((unsigned int)time(NULL));
switch (input)
{
case 1: game();
break;
case 0:printf("游戏结束\n");
break;
default:printf("请重新选择：\n");
}
} while (input);
system("pause");
return 0;
}3.包含所有函数的定义 game.c
#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"

{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{

{
board[i][j] = ' ';
}
}
}
void Displayboard(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
{
printf("|");
}
}printf("\n");
for (j = 0; j < col; j++)
{
if (i < row - 1)
{
printf("---");
}
if (i == col-1)
{
break;
}
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
}
/*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 Computer_move(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑走:>\n");
while (1)
{

y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = 'o';
break;
}
}
}

{
int x = 0;
int y = 0;
printf("请输入坐标：>\n");
while (1)
{
scanf("%d%d", &x, &y);
if (x > 0 && x <= row &&y >0 && y <= col && board[x-1][y-1] == ' ')
{
board[x - 1][y - 1] = 'x';
break;
}
else
printf("请重新输入坐标：>\n");
}
}
