实现人机对战三子棋，其文件组成形式为头文件和源文件形式，具体如下： game.h文件中放入函数的声明，以及用到的宏定义,以及头文件的包括. game.c文件中放的是各部分函数功能的实现. test.c文件中是测试函数，放的是整个程序实现的主逻辑. 各部分代码如下：

game.h

#ifndef __GANE_H__#define __GANE_H__ // 头文件组合形式#define ROWS 3 //行数#define COLS 3 //列数#include <stdio.h> //所用的头文件#include <stdlib.h> #include <time.h>#include<string.h>void PRint_board (char board[ROWS][COLS],int rows,int cols );//打印表格函数void init_board (char board[ROWS][COLS],int rows,int cols ); //初始化函数void player_move (char board[ROWS][COLS],int rows,int cols); //玩家移动函数void computer_move (char board[ROWS][COLS],int rows,int cols); //电脑移动函数char f_win(char board[ROWS][COLS],int rows,int cols); //检验函数#endif //__GANE_H__

game.c

#define _CRT_SECURE_NO_WARNINGS 1#include "stdio.h"#include "game.h"#include<string.h>void init_board(char board[ROWS][COLS],int rows,int cols ){ memset(board,' ',rows*cols*(sizeof(char)));}void print_board (char board[ROWS][COLS],int rows,int cols ){ int i = 0; for (i=0;i<cols;i++) { printf (" %c | %c | %c /n",board[i][0],board[i][1],board[i][2]); if (i!=(cols-1)) printf ("---|---|---/n"); }}void player_move (char board[ROWS][COLS],int rows,int cols){ int x = 0; int y = 0; printf ("请输入两个下标>:"); scanf ("%d%d",&x,&y); x--; y--; if ((x>=0)&&(x<=rows-1)&&(y>=0)&&(y<=cols-1)) { if (board[x][y]==' ') { board[x][y]='X'; } else { printf ("下标错误，请重新输入！"); } } else { printf ("输入有误！"); }}void computer_move (char board[ROWS][COLS],int rows,int cols){ while (1) { int x=rand()%3; int y=rand()%3; if (board[x][y]==' ') { board[x][y]='0'; break ; } }}static int f_full(char board[ROWS][COLS],int rows,int cols){ int i = 0; int j = 0; for (i=0;i<rows;i++) { for (j=0;j<cols;j++) if (board[i][j]==' ') return 0; } return 1;}char f_win(char board[ROWS][COLS],int rows,int cols){ int i =0; for (i=0;i<rows;i++) { if ((board[i][0]==board[i][1])&&(board[i][1]==board[i][2])&&(board[i][0])!=' ') return board[i][0]; }//判断每行的元素是否相同for (i=0;i<cols;i++) { if ((board[0][i]==board[1][i])&&(board[1][i]==board[2][i])&&(board[0][i])!=' ') return board[0][i]; }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[1][1])!=' ')return board [0][2];if (f_full(board,rows,cols)){ return 'p';}return ' ';}

test.c

#define _CRT_SECURE_NO_WARNINGS 1#include <stdio.h>#include <stdlib.h>#include <time.h>#include "game.h"void game (){ char board[ROWS][COLS]={0}; char ret = 0; init_board(board,ROWS,COLS); print_board(board,ROWS,COLS); srand((unsigned int)time(NULL)); while (1) { printf ("玩家走>/n"); player_move(board,ROWS,COLS); print_board(board,ROWS,COLS); if ((ret=f_win(board,ROWS,COLS))!=' ') break; printf ("电脑走>/n"); computer_move(board,ROWS,COLS); print_board(board,ROWS,COLS); if ((ret=f_win(board,ROWS,COLS))!=' ') break; } ret=f_win(board,ROWS,COLS); if (ret=='X') { printf ("恭喜你，赢了！/n"); } else if (ret=='0') { printf ("不好意思，你输了！/n"); } else if (ret=='p') { printf ("平局！/n"); } print_board(board,ROWS,COLS);}void menu (){ printf ("****************************/n"); printf ("***** 1.play 0.exit *****/n"); printf ("****************************/n");}int main(){ int input = 0; menu(); do { printf ("请选择>:"); scanf ("%d",&input); switch (input) { case 1: { game(); break ; } case 0: { break; } default: { printf("请重新输入>:"); break ; } } }while (input); return 0;}
