一.如何实现

1.说明：由于本文只是对初学C语言的人学习，所以将不会涉及任何算法，电脑将采用随机下子的方式。（后期会为大家介绍Alpha-Beta剪枝算法实现人工智能AI）

2.主要部分：

（1）菜单

（2）打印棋盘

（3）玩家下子

（4）电脑下子

（5）判断输赢

二.实现代码及分析

（1）菜单的制作

运用do…while循环调用菜单，根据用户选择实现玩游戏和退出游戏

（2）棋盘的初始化和打印

棋盘采用标准的15*15的格子，我们可以宏定义ROW和COL分别为15和15来表示行和列。

分别封装两个函数对棋盘进行初始化和打印

初始化：（这里将棋盘初始化为空格，可初始化为其他）

打印棋盘：

效果如下：

（3）玩家下子

void PlayerMove(char board[ROW][COL], int row, int col) { int x, y; while (1) { printf("玩家走： "); printf("请输入坐标： "); 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] = "O"; break; } else { printf("坐标被占用，请重新输入 "); } } else { printf("坐标非法，请重新输入 "); } } }

玩家下子主要采用的思路是，判断棋盘上是否有子，已经输入的坐标是否合法。

（4）电脑下子

void ComputerMove(char board[ROW][COL], int row, int col) { int x, y; printf("电脑走 "); while (1) { x = rand() % row; y = rand() % col; if (board[x][y] == " ") { board[x][y] = "X"; break; } } }

与玩家下子相同，此处采用的随机下子，后期可进行优化（比如：极大极小值算法、Alpha-Beta剪枝算法等）

（5）判断输赢

通过遍历整个棋盘，观察是否有连五子情况出现，代码如下：

char iswin(char board[ROW][COL], int row, int col) { //行 int ren=0,dian=0,i,j; for (i = 0;i < row;i++) { ren = 0; for (j = 0;j < col;j++) { if (board[i][j] == "O") ren++; else ren = 0; if (ren >= 5) return "o"; } } for (i = 0;i < row;i++) { dian = 0; for (j = 0;j < col;j++) { if (board[i][j] == "X") dian++; else dian = 0; if (dian >= 5) return "x"; } } //列 ren = dian = 0; for (i = 0;i < row;i++) { ren = 0; for (j = 0;j < col;j++) { if (board[j][i] == "O") ren++; else ren = 0; if (ren >= 5) return "o"; } } for (i = 0;i < row;i++) { dian = 0; for (j = 0;j < col;j++) { if (board[j][i] == "X") dian++; else dian = 0; if (dian >= 5) return "x"; } } //右下 ren = dian =i=j= 0; for (int k = 0;k < row;k++) { i = k; j = 0; ren = 0; while (i < row && j < col) { if (board[i][j] == "O") { ren++; } else { ren = 0; } i++; j++; if (ren >= 5) return "o"; } } i = j = 0; for (int k = 0;k < row;k++) { i = k; j = 0; dian = 0; while (i < row && j < col) { if (board[i][j] == "X") { dian++; } else dian = 0; i++; j++; if (dian >= 5) return "x"; } } //右上 for (int k = row;k >=0;k--) { j = col; i = k; ren = 0; while (i >=0 && j >=0) { if (board[i][j] == "O") { ren++; } else ren = 0; i--; j--; if (ren >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = col; dian = 0; while (i >= 0 && j >= 0) { if (board[i][j] == "X") { dian++; } else dian = 0; i--; j--; if (dian >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = 0; dian = 0; while (i >= 0 && j <col) { if (board[i][j] == "O") { dian++; } else dian = 0; i--; j++; if (dian >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = 0; dian = 0; while (i >= 0 && j <col) { if (board[i][j] == "X") { dian++; } else dian = 0; i--; j++; if (dian >= 5) return "x"; } } for (int k = 0;k < row;k++) { i = k; j = col; dian = 0; while (i < row && j >= 0) { if (board[i][j] == "O") { dian++; } else dian = 0; i++; j--; if (dian >= 5) return "o"; } } for (int k = 0;k <row;k++) { i = k; j = col; dian = 0; while (i <row && j >= 0) { if (board[i][j] == "X") { dian++; } else dian = 0; i++; j--; if (dian >= 5) return "x"; } } for (int k = row;k >= 0;k--) { i = k; j = 0; dian = 0; while (i >= 0 && j <col) { if (board[i][j] == "O") { dian++; } else dian = 0; i--; j++; if (dian >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = 0; dian = 0; while (i >= 0 && j <col) { if (board[i][j] == "X") { dian++; } else dian = 0; i--; j++; if (dian >= 5) return "x"; } } for (int k = 0;k < row;k++) { i = k; j = col; dian = 0; while (i < row && j >= 0) { if (board[i][j] == "O") { dian++; } else dian = 0; i++; j--; if (dian >= 5) return "o"; } } for (int k = 0;k <row;k++) { i = k; j = col; dian = 0; while (i <row && j >= 0) { if (board[i][j] == "X") { dian++; } else dian = 0; i++; j--; if (dian >= 5) return "x"; } } return "c"; //左 }

三.整个代码

（1）test.c文件下代码：

#define _CRT_SECURE_NO_WARNINGS 1 #include"game.h" void menu() { printf("************************** "); printf("******* 1. play ********* "); printf("******* 0. exit ********* "); printf("************************** "); } void game() { //棋盘数组 char board[ROW][COL],ret; //初始化棋盘 InitBoard(board, ROW, COL); //打印棋盘 PrintBoard(board, ROW, COL); //下棋 int a; printf("1.先手 0.后手"); scanf("%d", &a); if(a==1) PlayerMove(board, ROW, COL); else ComputerMove(board, ROW, COL); while (1) { if (a == 0) { //PlayerMove(board, ROW, COL); PlayerMove(board, ROW, COL); PrintBoard(board, ROW, COL); ret=iswin(board, ROW, COL); if (ret != "c") { break; } //ComputerMove(board, ROW, COL); ComputerMove(board, ROW, COL); PrintBoard(board, ROW, COL); ret = iswin(board, ROW, COL); if (ret != "c") { break; } } else { //ComputerMove(board, ROW, COL); ComputerMove(board, ROW, COL); PrintBoard(board, ROW, COL); ret = iswin(board, ROW, COL); if (ret != "c") { break; } //PlayerMove(board, ROW, COL); PlayerMove(board, ROW, COL); PrintBoard(board, ROW, COL); ret = iswin(board, ROW, COL); if (ret != "c") { break; } } } if (ret == "o") printf("玩家赢 "); else if (ret == "x") printf("电脑赢 "); else printf("平局 "); } int main() { int input; srand((unsigned int)time(NULL)); do { menu(); scanf("%d", &input); switch (input) { case 1: game(); break; case 0: printf("退出游戏 "); break; default: printf("选择错误 "); break; } } while (input); return 0; }

（2）game.c下的代码

#define _CRT_SECURE_NO_WARNINGS 1 #include"game.h" void InitBoard(char board[ROW][COL], int row, int col) { for (int i = 0;i < row;i++) { for (int j = 0;j < col;j++) { board[i][j] = " "; } } } void PrintBoard(char board[ROW][COL], int row, int col) { for (int i = 0;i < row;i++) { printf(" "); printf("%2d", i+1); } printf(" "); for (int i = 0;i < row;i++) { //打印数据 printf("%2d", i + 1); for (int j = 0;j < col;j++) { printf(" %c ", board[i][j]); if (j < col - 1) printf("|"); } printf(" "); //打印分割行 if (i < row - 1) { printf(" "); for (int j = 0;j < col;j++) { printf("---"); if (j < col-1) printf("|"); } printf(" "); } } } void PlayerMove(char board[ROW][COL], int row, int col) { int x, y; while (1) { printf("玩家走： "); printf("请输入坐标： "); 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] = "O"; break; } else { printf("坐标被占用，请重新输入 "); } } else { printf("坐标非法，请重新输入 "); } } } void ComputerMove(char board[ROW][COL], int row, int col) { int x, y; printf("电脑走 "); while (1) { x = rand() % row; y = rand() % col; if (board[x][y] == " ") { board[x][y] = "X"; break; } } } char iswin(char board[ROW][COL], int row, int col) { //行 int ren=0,dian=0,i,j; for (i = 0;i < row;i++) { ren = 0; for (j = 0;j < col;j++) { if (board[i][j] == "O") ren++; else ren = 0; if (ren >= 5) return "o"; } } for (i = 0;i < row;i++) { dian = 0; for (j = 0;j < col;j++) { if (board[i][j] == "X") dian++; else dian = 0; if (dian >= 5) return "x"; } } //列 ren = dian = 0; for (i = 0;i < row;i++) { ren = 0; for (j = 0;j < col;j++) { if (board[j][i] == "O") ren++; else ren = 0; if (ren >= 5) return "o"; } } for (i = 0;i < row;i++) { dian = 0; for (j = 0;j < col;j++) { if (board[j][i] == "X") dian++; else dian = 0; if (dian >= 5) return "x"; } } //右下 ren = dian =i=j= 0; for (int k = 0;k < row;k++) { i = k; j = 0; ren = 0; while (i < row && j < col) { if (board[i][j] == "O") { ren++; } else { ren = 0; } i++; j++; if (ren >= 5) return "o"; } } i = j = 0; for (int k = 0;k < row;k++) { i = k; j = 0; dian = 0; while (i < row && j < col) { if (board[i][j] == "X") { dian++; } else dian = 0; i++; j++; if (dian >= 5) return "x"; } } //右上 for (int k = row;k >=0;k--) { j = col; i = k; ren = 0; while (i >=0 && j >=0) { if (board[i][j] == "O") { ren++; } else ren = 0; i--; j--; if (ren >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = col; dian = 0; while (i >= 0 && j >= 0) { if (board[i][j] == "X") { dian++; } else dian = 0; i--; j--; if (dian >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = 0; dian = 0; while (i >= 0 && j <col) { if (board[i][j] == "O") { dian++; } else dian = 0; i--; j++; if (dian >= 5) return "o"; } } for (int k = row;k >= 0;k--) { i = k; j = 0; dian = 0; while (i >= 0 && j <col) { if (board[i][j] == "X") { dian++; } else dian = 0; i--; j++; if (dian >= 5) return "x"; } } for (int k = 0;k < row;k++) { i = k; j = col; dian = 0; while (i < row && j >= 0) { if (board[i][j] == "O") { dian++; } else dian = 0; i++; j--; if (dian >= 5) return "o"; } } for (int k = 0;k <row;k++) { i = k; j = col; dian = 0; while (i <row && j >= 0) { if (board[i][j] == "X") { dian++; } else dian = 0; i++; j--; if (dian >= 5) return "x"; } } return "c"; //左 }

（3）game.h下的代码

#pragma once #define ROW 15 #define COL 15 #include<stdio.h> #include<stdlib.h> #include<time.h> //初始化棋盘 void InitBoard(char board[ROW][COL], int row, int col); //打印棋盘 void PrintBoard(char board[ROW][COL], int row, int col); //人走 void PlayerMove(char board[ROW][COL], int row, int col); //电脑走 void ComputerMove(char board[ROW][COL], int row, int col); //判断输赢 char iswin(char board[ROW][COL], int row, int col);

四.具体效果

1.棋盘打印以及选择先后手

2.玩家和电脑下子

3.判断输赢

此处我们看到玩家赢了，可是电脑实在太蠢了，所以还有很多地方需要添加的

欢迎各位大佬对此代码进行优化！
