1.创建菜单和实现方法

2.创建并初始化二维数组

3.打印棋盘

4.双方下棋

1）玩家下棋

2）电脑下棋

5.判断胜负

1.打印游戏菜单

2.创建并初始化二维数组

3.打印棋盘

4.双方下棋

5.判断胜负

# 二、创建文件

test.c文件用于实现进入游戏、退出游戏、判断输赢、打印菜单等逻辑

game.c用于编写游戏的主要实现方法

game.h存放头文件和函数的声明

# 三、具体步骤

## 1.创建菜单和实现方法

``````void menu()
{
printf("********************************n");
printf("*********   1.play   ***********n");
printf("*********   0.exit   ***********n");
printf("********************************n");
}
void test()
{
srand((unsigned int)time(NULL));
int input = 0;
do
{
printf(":>");

scanf("%d", &input);
switch (input)
{
case 1:
printf("三子棋游戏开始n");
game();
break;
case 0:
printf("结束游戏n");
break;
default:
printf("输入错误n");
break;

}
} while (input);
}``````

## 2.创建并初始化二维数组

``````void game()
{
//创建二维数组
char board[ROW][COL] = { 0 };
//初始化二维数组
InitBoard(board, ROW, COL);
}``````

``````#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>
#include<stdlib.h>
#define ROW 3
#define COL 3``````

``````#include "game.h"
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] = ' ';
}
}
}``````

## 3.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");
if (i < row - 1)
{
for (j = 0; j < row; j++)
{
printf("---");
if (j < col - 1)
{
printf("|");
}
}
}
printf("n");
}
}``````

## 4.双方下棋

``````//下棋
while (1)
{
//玩家下棋
player_move(board, ROW, COL);
DisplayBoard(board, ROW, COL);
//电脑下棋
computer_move(board, ROW, COL);
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
}``````

### 1）玩家下棋

``````void player_move(char board[ROW][COL], int row, int col)
{
printf("玩家下棋:>");
int x = 0;
int y = 0;

while (1)
{
scanf("%d %d", &x, &y);
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else
printf("该坐标被占用，请重新输入！n");
}
else
printf("坐标非法,请重新输入！n");
}

}``````

### 2）电脑下棋

``````void computer_move(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑下棋:>n");
while (1)
{
x = rand() % ROW;
y = rand() % COL;
if (board[x][y]== ' ')
{
board[x][y] = '#';
break;
}
}
}``````

## 5.判断胜负

``````//玩家赢:'*'
//电脑赢:'#'
//平局:Q
//继续:C
int is_full(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++)
{
if (board[i][j] == ' ')
{
return 0;
}
}
}
return 1;
}
char is_win(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
{
return board[i][1];
}
}
for (i = 0; i < row; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
{
return board[1][i];
}
}
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
{
return board[1][1];
}
if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
{
return board[1][1];
}
if (is_full(board, row, col)==1)
{
return 'Q';
}
//继续
return 'C';
}``````

``````char ret = 0;
while (1)
{
//玩家下棋
player_move(board, ROW, COL);
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
if (ret != 'C')
{
break;
}
//电脑下棋
computer_move(board, ROW, COL);
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
if (ret != 'C')
{
break;
}
}
//判断胜负
if (ret == '*')
{
printf("玩家赢了！n");
}
else if (ret == '#')
{
printf("电脑赢了！n");
}
else
{
printf("平局n");
}
