C/C++实现三子棋
首先声明头文件/game.h/
#ifndef __GAME_H__
#define __GAME_H__
//#pragma once //预防头文件重复引用
#include<stdio.h>
#include<windows.h>
#define ROW 3
#define COL 3
void InitBoard(char board[][COL], int row, int col);
void ShowBoard(char board[][COL], int row, int col);
void PlayerMove(char board[][COL], int row, int col);
void ComputerMove(char board[][COL], int row, int col);
char IsWin(char board[][COL], int row, int col);
第二步：建一个/game.c/文件
#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"
void InitBoard(char board[][COL], int row, int col) //设计界面背景（棋单）
{
//采用二维数组board[][]画棋单
for (int i = 0; i < row; i++){
for (int j = 0; j < col; j++){
board[i][j] = ' ';
}
}
}
//构造好后显示棋单的函数
void ShowBoard(char board[][COL], int row, int col)
{
printf("****************************\n");
for (int i = 0; i < row; i++){
for (int j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1){
printf("|");
}
}
printf("\n"); //--- 控制行数
if (i < row - 1)
{
//循环控制---的列数
for (int j = 0; j < col; j++)
{
printf("---");
if (j < col - 1){
printf("|");
}
}
printf("\n");
}
}
printf("****************************\n");
}
//玩家选择棋子放到哪儿
void PlayerMove(char board[][COL], int row, int col)
{
int x = 0;
int y = 0;
while (1)
{
printf("请输入你的1-3坐标：\n");
scanf_s("%d%d", &x, &y);//1 3 --> 0 2
if (x >= 1 && x <= 3 && y >= 1 && y <= 3)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = 'X';
break;
}
}
else
{
printf("坐标不合法，请重新输入：\n");
}
}
}
//电脑随机匹配放棋子
void ComputerMove(char board[][COL], int row, int col)
{
while (1)
{
int x = rand() % ROW;//row==3 --> 0,1,2
int y = rand() % COL;
if (board[x][y] == ' ')
{
board[x][y] = 'O';
break;
}
}
}
//设计函数判断是玩家赢还是电脑赢
char IsWin(char board[][COL], int row, int col)
{
for (int i = 0; i < row; i++)
{
//行
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] &&board[i][0] != ' ')
{
return board[i][0];
}
//列
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] &&board[0][i] != ' ')
{
return board[0][i];
}
//对角线
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] &&board[0][0] != ' ')
{
return board[0][0];
}
if (board[0][2] == board[1][1] && board[1][1] == board[2][0] &&board[0][2] != ' ')
{
return board[0][2];
}
if (IsFull(board, row, col) == 1) //是否是平局--》棋盘里面已经放满了
{
return 'Q';//证明是平局
}
}
return ' ';//代表没有人赢
}
static int IsFull(char board[][COL], int row, int col)
{
for (int i = 0; i < row; i++)
{
for (int j = 0; j < col; j++)
{
if (board[i][j] == ' ')
{
return 0;//没有满
}
}
}
return 1;//满
}
第三步：建一个/test.c/文件，通过条件调用函数，就可以开始玩游戏啦
#define _CRT_SECURE_NO_WARNINGS 1
#include"game.h"
void menu()
{
printf("***********************\n");
printf("********0.exit********\n");
printf("********1.play**********\n");
printf("***********************\n");
}
void game()
{
//printf("玩游戏\n");
char board[ROW][COL] = {
0 };
InitBoard(board, ROW, COL);
ShowBoard(board, ROW, COL);
int ret = 0;
while (1)
{
PlayerMove(board, ROW, COL);
ShowBoard(board, ROW, COL);
ret = IsWin(board, ROW, COL);
if (ret != ' ')
{
break;//肯定有一个人赢了
}
ComputerMove(board, ROW, COL);
ShowBoard(board, ROW, COL);
ret = IsWin(board, ROW, COL);
if (ret != ' ')
{
break;//肯定有一个人赢了
}
}
if (ret == ' Q')
{
printf("平局\n");
return;
}
if (ret == 'X')
{
printf("玩家赢\n");
return;
}
if (ret == 'O')
{
printf("电脑赢\n");
return;
}
}
int main() //主函数调用子函数
{
srand((unsigned)time(NULL)); //控制电脑随机放置棋子
int input = 0;
printf("请输入你的操作：\n");
do
{
menu(); //调用菜单函数
scanf_s("%d", &input);
switch (input)
{
case 1: //如果输入为1，则调用game()函数
game();
break;
case 0: //如果为0，则退出游戏
printf("退出游戏\n");
break;
default:
break;
}
}
while (input);
system("pause");
return 0;
}
