三子棋

用C语言实现，三子棋。

整个程序大体由三部分组成，分别是game.h , test.c , game.c

game.h

#define _CRT_SECURE_NO_WARNINGS#ifndef __GAME1_H__#define __GAME1_H__#include <stdio.h>#include <time.h>#include <stdlib.h>#define ROWS 3#define COLS 3void init_board(char arr[ROWS][COLS], int row, int col);void display(char arr[ROWS][COLS], int row, int col);void computer_move(char arr[ROWS][COLS], int row, int col);void player_move(char arr[ROWS][COLS], int row, int col);char check_win(char arr[ROWS][COLS], int row, int col);int is_full(char arr[ROWS][COLS], int row, int col);#endif

test.c

#include <stdio.h>#include "game.h"void menu(){printf("******************************\n");printf("******  1.play  0.exit  ******\n");printf("******************************\n");}void game(){char arr[ROWS][COLS] = {0};char win = 0;init_board(arr, ROWS, COLS);display(arr, ROWS, COLS);    srand((unsigned int)time(NULL));do {computer_move(arr, ROWS, COLS);win = check_win(arr, ROWS, COLS);if(win != ' '){break;}display(arr, ROWS, COLS);player_move(arr, ROWS, COLS);win = check_win(arr, ROWS, COLS);if(win != ' '){break;}    display(arr, ROWS, COLS);} while(win == ' ');if(win == 'X'){printf("玩家赢\n");}else if(win == '0'){printf("电脑赢\n");}else if(win == 'H'){printf("平局\n");}display(arr, ROWS, COLS);}void test(){int input = 0;do{menu();printf("请输入>:");scanf("%d",&input);switch(input){case 1:game();break;case 0:printf("exit\n");break;default:printf("输入错误\n");break;}}while(input);}int main(){test();return 0;}

game.c

#include "game.h"#include <string.h>void init_board(char arr[ROWS][COLS], int row, int col){int i = 0;int j = 0;memset(arr, ' ', row*col*sizeof(arr[0][0]));//设置内存，将数组所有元素制为空格(' ')}void display(char arr[ROWS][COLS], int row, int col){int i = 0;for(i=0; i<row; i++){printf(" %c | %c | %c \n",arr[i][0],arr[i][1],arr[i][2]);if(i != (row-1))printf("---|---|---\n");}}void computer_move(char arr[ROWS][COLS], int row, int col){    printf("电脑下\n");while(1){int x = rand()%3;int y = rand()%3;if(arr[x][y] == ' '){arr[x][y] = '0';break;}}}void player_move(char arr[ROWS][COLS], int row, int col){int x = 0;int y = 0;while(1){printf("请选择输入坐标:\n");scanf("%d%d", &x, &y);if(((x>=1)&&(x<=3))&&((y>=1)&&(y<=3))){if(arr[x-1][y-1] == ' '){arr[x-1][y-1] = 'X';break;}else{printf("此处已有棋子\n");}}else{printf("输入坐标有误\n");}}}char check_win(char arr[ROWS][COLS], int row, int col){int i = 0;for(i=0; i<row; i++){if((arr[i][0]==arr[i][1])&&(arr[i][1]==arr[i][2])&&(arr[i][0]!=' ')){return arr[i][0];}}for(i=0; i<row; i++){if((arr[0][i]==arr[1][i])&&(arr[1][i]==arr[2][i])&&(arr[0][i]!=' ')){return arr[0][i];}}if((arr[0][0]==arr[1][1])&&(arr[1][1]==arr[2][2])&&(arr[0][0]!=' ')){return arr[1][1];}if((arr[0][2]==arr[1][1])&&(arr[1][1]==arr[2][0])&&(arr[0][0]!=' ')){return arr[1][1];}if(is_full(arr, row, col) == 1){return 'H';}return ' ';}int is_full(char arr[ROWS][COLS], int row, int col){int i = 0;int j = 0;for(i=0; i<row; i++){for(j=0; j<col; j++){if(arr[i][j] == ' ')return 0;}}return 1;}

结果有三种，分别如下：

1) 玩家赢

2)电脑赢

3)平局

总体来说，其核心是利用二位数组。首先对棋盘进行赋值，用memset()对棋盘制空，用printf来构建棋盘的外形。其次，利用rand()来制出随机值，模拟电脑下棋，玩家输入的坐标，来确定下棋的位置。最后，通过二维数组来模拟比赛的结果。
