C语言编程实现三子棋

源码：

1.函数头：

#ifndef __GAME_H__#define __GAME_H__#include <stdio.h>#include <stdlib.h>#include <string.h>#include <time.h>#define  ROW  3//棋盘初始化大小#define  COL  3void init_board(char board[ROW][COL], int row, int col);//棋盘初始化void display_board(char board[ROW][COL], int row, int col);//棋盘打印void player_move(char board[ROW][COL], int row, int col);void computer_move(char board[ROW][COL], int row, int col);char check_win(char board[ROW][COL], int row, int col);#endif //__GAME_H__

2.主函数：

#include "game.h"void menu()//界面{printf("*****************************************\n");printf("*******    1.play      0.exit    ********\n");printf("*****************************************\n");}void game()//游戏函数{int ret = 0;char board[ROW][COL] = { 0 };//棋盘数组srand((unsigned int)time(NULL));init_board(board, ROW, COL);while (1) //电脑先走，然后判断输赢，玩家走，接着判断输赢{computer_move(board, ROW, COL);if ((ret = check_win(board, ROW, COL)) != ' '){break;}display_board(board, ROW, COL);player_move(board, ROW, COL);if ((ret = check_win(board, ROW, COL)) != ' '){break;}display_board(board, ROW, COL);}if (ret == '*'){printf("you win!\n");}else if (ret == 'o'){printf("computer win!\n");}else if (ret == 'q'){printf("平局！");}display_board(board, ROW, COL);}int main(){int input = 0;do{menu();scanf("%d", &input);switch (input){case 0:break;case 1:game();break;default:printf("enter error! please enter again:\n");break;}}while(input);return 0;}

3.游戏函数主体：

#include "game.h"void init_board(char board[ROW][COL], int row, int col){memset(board, ' ', col*row*sizeof(char));//memset是以字节为单位，初始化内存块。当初始化一个字节单位的数组时，//可以用memset把每个数组单元初始化成任何你想要的值}void display_board(char board[ROW][COL], int row, int col){int i = 0;for (i = 0; i < row; i++){printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);if (i != 2){printf("---|---|---\n");}}}void player_move(char board[ROW][COL], int row, int col){int a = 0;int b = 0;while (1){printf("请输入坐标(a,b):\n");scanf("%d%d", &a, &b);a--;b--;if (((a >= 0) && (a <= 2)) &&((b >= 0) && (b <= 2))){if (board[a][b] == ' '){board[a][b] = '*';break;}else{printf("此处已落子！\n");}}else{printf("坐标错误！\n");}}}void computer_move(char board[ROW][COL], int row, int col){while (1){int a = rand() % row;int b = rand() % col;if (board[a][b] == ' '){board[a][b] = 'o';break;}}}static is_full(char board[ROW][COL], int row, int col){int i = 0;int j = 0;for (i = 0; i < row; i++){for (j = 0; j < col; j++){if (board[i][j] == ' '){return 0;}}}return 1;}char check_win(char board[ROW][COL], int row, int col){int i = 0;for (i = 0; i<row; i++){if ((board[i][0] == board[i][1])&& (board[i][1] == board[i][2])&& (board[i][1] != ' '))return board[i][1];}for (i = 0; i<col; i++){if ((board[0][i] == board[1][i])&& (board[1][i] == board[2][i])&& (board[1][i] != ' '))return board[1][i];}if ((board[0][0] == board[1][1])&& (board[1][1] == board[2][2])&& (board[1][1] != ' '))return board[1][1];if ((board[0][2] == board[1][1])&& (board[1][1] == board[2][0])&& (board[1][1] != ' '))return board[1][1];if (is_full(board, row, col)){return 'q';}return ' ';}
