C语言实现简单的三子棋小游戏

函数实现的基本功能：

1.初始化棋盘：用空字符初始化

2.打印棋盘：控制打印九宫格来表示棋盘

3.玩家下棋：用P表示玩家的棋子

4.电脑随机下棋：随机生成坐标，用0表示玩家的棋子

5.判断输赢：玩家赢，电脑赢，平局，继续游戏四种情况

多文件实现：

测试部分test.c代码

#include<windows.h>
#include"game.h"
menu()
{
printf("###############################\n");
printf("#######欢迎来到三子棋游戏######\n");
printf("####### 1.play    0.exit ######\n");
printf("###############################\n");
}
void game()
{
char board[ROW][COL] = { 0 };
char win = 0;
InitBoard(board, ROW, COL);//初始化空格棋盘
//打印棋盘
PrintBoard(board, ROW, COL);
do
{
PlayerMove(board, ROW, COL);//玩家走
PrintBoard(board, ROW, COL);
win = CheckWin(board, ROW, COL);//检测输赢;玩家赢P 电脑赢0  继续游戏 平局E
if (win != ' ')
break;
ComputerMove(board, ROW, COL);//电脑走
PrintBoard(board, ROW, COL);
win = CheckWin(board, ROW, COL);
if (win != ' ')
{

break;
PrintBoard(board, ROW, COL);

}
}
while (1);
if (win == 'P')
printf("恭喜你你赢了\n");
else if (win == '0')

printf("不好意思电脑赢了\n");
else if (win == 'E')
printf("平局\n");

}

void test()
{
int input = 0;
srand((unsigned)time(NULL));
do{
menu();//打印菜单
printf("请选择;>");
scanf_s("%d",&input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏\n");
break;
default:
printf("选择错误\n");
break;
}
} while (input);
}

int main()
{
test();

system("pause");
return 0;
}

游戏头文件game.h代码

#ifndef  _GAME_H_
#define  _GAME_H_

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

#define ROW 3
#define COL 3

void InitBoard(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 CheckWin(char board[ROW][COL], int row, int col);
#endif

游戏实现部分game.c

#include<stdio.h>
#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 < row; j++)
{
board[i][j] = ' ';
}
}

}
void PrintBoard(char board[ROW][COL], int row, int col)
{
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)
{
int x = 0;
int y = 0;
while (1)
{
printf("玩家下棋>:");
scanf_s("%d%d", &x, &y);
if (x >= 1 && x <= ROW && y>= 1 && y<= COL)//判断坐标合法性
{
//判断坐标是否被走过
if (board[x-1][y-1] == ' ')
{
board[x-1][y-1] = 'P';
break;
}
else
printf("该步已经被走过\n");
}
else
printf("坐标输入有误请重新输入\n");

}

}
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;//不满返回0
}
}return 1;//满了返回1
}
void ComputerMove(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;//随机值0-2
y = rand() % COL;//随机值0-2
if (board[x][y] == ' ')
{
board[x][y] = '0';
break;
}

}
}
char CheckWin(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][0] == board[i][2] && board[i][0] != ' ')
{
return board[i][0];
}
}//处理行相等
for (i = 0; i < row; i++)
{
if (board[0][i] == board[1][i] && board[0][i] == board[2][i] && board[0][i] != ' ')
{
return board[0][i];
}
}//处理列相等

if (board[0][0] == board[1][1] && board[0][0] == board[2][2] && board[0][0] != ' ')
{
return board[1][1];
}
if (board[0][2] == board[1][1] && board[0][2] == board[2][0] && board[0][2] != ' ')
{
return board[1][1];
}//处理对角线相等

if (is_full(board, row, col) == 1)
{
return'E';

}return' ';

}

以上只是简单的实现部分，还望各位大佬多多指点！
