井字棋是一个很常见的小游戏。要求对战双方在一个“井”形的棋盘里分别下“*”棋子或者“#”棋子，谁先连成3个，谁就赢。
本次使用C语言来实现这个小游戏。
由于使用函数较多，所以采用多文件的方式方便梳理代码思路。
本次一共有三个文件：
**
game.h：
包含了game.c文件中函数的声明和库函数的声明。**
#pragma once#define ROW 3#define COL 3#include<stdio.h>#include<stdlib.h>#include<time.h>void InitBoard(char board [ROW][COL], int row, int col); //初始化棋盘void DisplayBoard(char board [ROW][COL], int row, int col); //打印棋盘void PlayerBoard(char board [ROW][COL], int row, int col); //玩家走void ComputerBoard(char board [ROW][COL], int row, int col);//电脑走char IsWin(char board [ROW][COL], int row, int col); //结果判断
game.c：
包含游戏过程中关键函数的函数主体。
#define _CRT_SECURE_NO_WARNINGS#include"game.h"void InitBoard(char board[ROW][COL], int row, int col){ //初始化棋盘 int i = 0; for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col; j++) board [i][j] = ' '; }}void DisplayBoard(char board [ROW][COL], int row, int col){ //打印棋盘 int i = 0; for (i = 0; i < row; i++) { int j = 0; 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 PlayerBoard(char board [ROW][COL], int row, int col){ int x = 0, y = 0; while (1) { printf("输入棋子坐标->"); scanf("%d%d", &x, &y); if (x > 0 && x <= row && y > 0 && y <= col) { if (board [x - 1][y - 1] == ' ') { board [x - 1][y - 1] = '*'; break; } else { printf("此位置已有棋子！请重新输入。\n"); } } else { printf("输入错误！请重新输入。\n"); } }}void ComputerBoard(char board [ROW][COL], int row, int col){ int x = 0, y = 0; while (1) { x = rand() % row; y = rand() % col; if (board [x][y] != ' ') { continue; } else { board [x][y] = '#'; break; } }}int IsFull(char board [ROW][COL], int row, int col){ int i = 0; for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col; j++) { if (board [i][j] == ' ') return 0; } } return 1;}char IsWin(char board [ROW][COL], int row, int col){ int i = 0; //行 for (i = 0; i < row; i++) { if (board [i][0] == board [i][1] && board [i][1] == board [i][2] && board [i][0] != ' ') return board [i][0]; } //列 for (i = 0; i < col; i++) { 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 [1][1] != ' ') return board [1][1]; if (board [2][0] == board [1][1] && board [1][1] == board [0][2] & board [1][1] != ' ') return board [1][1]; //是否平局 if (IsFull(board, row, col)) return 'Q';//平局 return 'C';//继续}
test.c：
main函数和游戏的大概流程。
#define _CRT_SECURE_NO_WARNINGS#include"game.h"void Menu(){ printf("*******************************\n"); printf("********** 1、play **********\n"); printf("********** 0、quit **********\n"); printf("*******************************\n");}void game(){ char board [ROW][COL]; InitBoard(board, ROW, COL); DisplayBoard(board, ROW, COL); char ret = 0; srand((unsigned int) time(NULL)); while (1) { printf("玩家走\n"); PlayerBoard(board, ROW, COL); DisplayBoard(board, ROW, COL); ret = IsWin(board, ROW, COL); if (ret != 'C') break; printf("电脑走\n"); ComputerBoard(board, ROW, COL); DisplayBoard(board, ROW, COL); ret = IsWin(board, ROW, COL); if (ret != 'C') break; } if (ret == '*') printf("玩家胜利！\n"); else if (ret == '#') printf("电脑胜利！\n"); else printf("平局！\n");}int main(){ //三子棋 int input = 1; while (input) { Menu(); printf("输入1开始游戏，输入0退出游戏。\n请输入->"); scanf("%d", &input); switch(input) { case 1: game(); printf("开始游戏\n"); break; case 0: printf("游戏结束\n"); break; default: printf("非法输入，请重试！\n"); } } return 0;}
