C语言实现三子棋
话不多说，直接上内容：
首先建立一个test.c文件，作为主体部分。再建立一个game.c文件作为游戏设计部分，最后建立一个game.h头文件申明函数。
欲实现的功能：
1、棋盘初始化
2、玩家下棋
3、电脑下棋
4、判断输赢
（1）玩家赢
（2）电脑赢
（3）平局
游戏主体部分代码：
#define _CRT_SECURE_NO_WARNINGS 1
#include
#include "game.h"
void menu()
{
printf("*************************************\n");
printf("**************1. play****************\n");
printf("**************0. exit****************\n");
printf("*************************************\n");
}
void game()
{
char board[ROW][COL] = { 0 };
TnitBoard(board, ROW, COL);
DisplayBoard(board, ROW, COL);
char ret = 0;
while (1)
{
player_move(board,ROW,COL);
DisplayBoard(board,ROW, COL);
ret = is_win(board, ROW, COL);
if (ret!='C')
{
break;
}
computer_move(board, ROW, COL);
DisplayBoard(board, ROW, COL);
if (ret !='C')
{
break;
}
}
if (ret=='*')
{
printf("玩家赢\n");
}
else if (ret == '#')
{
printf("电脑赢\n");
}
else {
printf("平局\n");
}
}
void test()
{
int input = 0;
do {
menu();
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();
return 0;
}
游戏设计部分代码：
#define _CRT_SECURE_NO_WARNINGS 1
#include
#include "game.h"
void TnitBoard(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] = ' ';
}
}
}
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 < col;j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
}
printf("\n");
}
}
void player_move(char board[ROW][COL], int row, int col)
{
printf("玩家下棋：>");
int x = 0;
int y = 0;
scanf_s("%d %d", &x, &y);
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
}
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");
}
}
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()%3;
y = rand()%3;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
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 < col;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 (1 == is_full(board, row, col))
{
return 'Q';
}
return 'C';
}
最后头文件函数声明：
#pragma once
#include
#include
#include
#define ROW 3
#define COL 3
void TnitBoard(char board[ROW][COL],int row,int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void player_move(char board[ROW][COL], int row, int col);
void computer_move(char board[ROW][COL], int row, int col);
char is_win(char board[ROW][COL], int row, int col);

时间仓促，要是有不得的地方欢迎评论或私聊！ 谢谢！
