在VS编译器的小黑框框里实现5x5棋盘的的三子棋

程序包括test.c（游戏测试）game.c（游戏源文件）和game.h（头文件）三个部分

game.h

#ifndef __GAME_H__#define __GAME_H__#define ROWS 5   //定义棋盘的行数#define COLS 5   //定义棋盘的列数#include <stdio.h>#include <stdlib.h>#include <time.h>#include <string.h> void init_board(char board[ROWS][COLS], int row, int col);   //初始化棋盘 void display(char board[ROWS][COLS], int row, int col);      //打印5*5的棋盘 void player_move(char board[ROWS][COLS], int row, int col);  //玩家下棋 void computer_move(char board[ROWS][COLS], int row, int col);//电脑下棋 char check_win(char board[ROWS][COLS], int row, int col);    //判断是否赢#endif //__GAME_H__

game.c

#define _CRT_SECURE_NO_WARNINGS 1#include "game.h"#include <string.h>void init_board(char board[ROWS][COLS], int row, int col)  //初始化棋盘{memset(board, ' ', sizeof(board[0][0])*row*col);}void display(char board[ROWS][COLS], int row, int col)     //打印棋盘{int i = 0;for (i = 0; i < row; i++){printf(" %c | %c | %c | %c | %c \n", board[i][0], board[i][1], board[i][2], board[i][3], board[i][4]);if (i < row - 1){printf("---|---|---|---|---\n");}}}void player_move(char board[ROWS][COLS], int row, int col)   //玩家下棋{int x = 0;int y = 0;while (1){printf("请输入坐标:> ");scanf("%d%d", &x, &y);if (((x>=1)&&(x<=row)) && ((y>=1) && (y<=col)))  //row-3{if (board[x-1][y-1] == ' '){board[x-1][y-1] = 'X';break;}else{printf("该坐标已被用，请重新输入\n");}}else{printf("输入坐标有误\n");}}}void computer_move(char board[ROWS][COLS], int row, int col)   //电脑下棋{while (1){int x = rand() % 5;int y = rand() % 5;if (board[x][y] == ' '){board[x][y] = '$';break;}}}int is_full(char board[ROWS][COLS], int row, int col){int i = 0;int j = 0;for (i = 0; i < row; i++){for (j = 0; j < row; j++){if (board[i][j] == ' '){return 0;}}}return 1;}char check_win(char board[ROWS][COLS], int row, int col)    //判断输赢{int i = 0;int j = 0;for (i = 0; i < row; i++) //行相同{for (j = 0; j < col; j++){if ((board[i][j] == board[i][j+1]) && (board[i][j+1] == board[i][j+2]) && (board[i][j+1] != ' ')){return board[i][j+1];}}}for (i = 0; i < row; i++) //列相同{for (j = 0; j < col; j++){if ((board[j][i] == board[j+1][i]) && (board[j+1][i] == board[j+2][i]) && (board[j+1][i] != ' ')){return board[j+1][i];}}}for (i = 0; i < row; i++){for (j = 0; j < col; j++){if ((board[i][j] == board[i+1][j+1]) && (board[i+1][j+1] == board[i+2][j+2]) && (board[i+1][j+1] != ' '))//斜相同{return board[i+1][j+1];}}}for (i = 0; i < row; i++){for (j = 0; j < col; j++){if ((board[i][j+2] == board[i+1][j+1]) && (board[i+1][j+1] == board[i+2][j]) && (board[i+1][j+1] != ' ')){return board[i+1][j+1];}}}if (is_full(board, row, col) == 1)   //如果棋盘没有空，返回q{return 'q';}return ' ';  //没输没赢，返回空格，继续下棋}

test.c

#define _CRT_SECURE_NO_WARNINGS 1#include "game.h"void menu()  //菜单打印{printf("***************************\n");printf("****  1.play   0.exit  ****\n");printf("***************************\n");}void game()  //游戏函数{char board[ROWS][COLS] = { 0 };char ret = 0;init_board(board, ROWS, COLS);      //初始化棋盘while (1){printf("玩家移动,");player_move(board, ROWS, COLS);  //玩家下棋display(board, ROWS, COLS);      //打印棋盘ret = check_win(board, ROWS, COLS);  //判断是否赢if (ret != ' '){break;}printf("电脑移动\n");computer_move(board, ROWS, COLS);display(board, ROWS, COLS);ret = check_win(board, ROWS, COLS);if (ret != ' '){break;}}if (ret == 'X'){printf("玩家赢\n");}else if (ret == '$'){printf("电脑赢\n");}else if (ret == 'q'){printf("平局\n");}}void test()   //测试函数{int input = 0;srand((unsigned int)time(NULL));   do{menu();printf("请输入你的选择:> ");    //选择是否开始游戏scanf("%d", &input);switch (input){case 1:game();break;case 0:break;default:printf("输入有误\n");break;}} while (input);}int main(){test();return 0;}

运行结果：
