Keener_Tic_Tac_Toe(井字棋游戏)代码(c语言)

遇到的问题:

1.中间有需要清楚键盘缓冲区,具体(?)

2.number char型,强制int型转换是利用ASCII码,相差48.

3.string型c++支持,c并没有,利用char型字符数组解决,char player1[20];scanf("%s",player1);printf("%s",player1);

代码如下:

#include <stdio.h>
#include <ctype.h>
#include <stdbool.h>
#include <stdlib.h>
#include <time.h>


int main(){

	//初始化
	char another_game = 'Y';
	char game[3][3] = {{'1','2','3'},{'4','5','6'},{'7','8','9'}};
	bool win = true;
	int choose_player = 0;
	char number = '0';
	int row = 0 , col = 0;
	bool take_turns = false;
	char player1[20],player2[20];
	int c;

	//循环_1
	do{
		//初始化游戏
		printf("井字棋游戏初始化...\n");
		char game[3][3] = {{'1','2','3'},{'4','5','6'},{'7','8','9'}};
		win = false;

		//输入玩家1,2姓名
		printf("(不要使用空格,回车键结束)\n");
		printf("请输入玩家1姓名:\n");
		scanf("%s",player1);
		printf("请输入玩家2姓名:\n");
		scanf("%s",player2);

		//随机选择先落子玩家
		srand((unsigned)time(NULL));
		choose_player = rand()%2 + 1;
		if(choose_player == 1){
			take_turns = true;
			printf("%s(玩家1)首先落子(1~9).\n",player1);
		}else{
			take_turns = false;
			printf("%s(玩家2)首先落子(1~9).\n",player2);
		}
	
		//循环_2
		while(!win){
			//输出3x3游戏格
			printf("\n");
			printf(" %c | %c | %c \n",game[0][0],game[0][1],game[0][2]);
			printf("---+---+---\n");
			printf(" %c | %c | %c \n",game[1][0],game[1][1],game[1][2]);
			printf("---+---+---\n");
			printf(" %c | %c | %c \n",game[2][0],game[2][1],game[2][2]);
			printf("\n");


			//玩家1,玩家2分别下棋
			//落子是否有效
			do{
				printf("%s落子:",take_turns?player1:player2);
				//这里需要清楚缓冲区(why?)
				if(feof(stdin) || ferror(stdin)){
					break;
				}
				while((c = getchar()) != '\n' && c != EOF);
				scanf("%c",&number);
				
				//why:ASCII码表对应的数字差48~
				row = ((int)number-48-1)/3;
				col = ((int)number-48-1)%3;
				//printf("%d.%d.%c.\n",row,col,game[row][col]);
				//printf("%c\n",number);
			}while( game[row][col] != number);

			//更新棋盘
			if(take_turns){
				game[row][col] = 'X';
			}else{
				game[row][col] = 'O';
			}

			//循环_2,判定:是否有人胜利
			if((game[0][0] == game[0][1] && game[0][1] == game[0][2])||
				(game[1][0] == game[1][1] && game[1][1] == game[1][2])||
				(game[2][0] == game[2][1] && game[2][1] == game[2][2])||
				(game[0][0] == game[1][0] && game[1][0] == game[2][0])||
				(game[0][1] == game[1][1] && game[1][1] == game[2][1])||
				(game[0][2] == game[1][2] && game[1][2] == game[2][2])||
				(game[0][0] == game[1][1] && game[1][1] == game[2][2])||
				(game[0][2] == game[1][1] && game[1][1] == game[2][0])
			){
				win = true;
				printf("%s胜利!游戏结束.",take_turns?player1:player2);

				printf("\n");
				printf(" %c | %c | %c \n",game[0][0],game[0][1],game[0][2]);
				printf("---+---+---\n");
				printf(" %c | %c | %c \n",game[1][0],game[1][1],game[1][2]);
				printf("---+---+---\n");
				printf(" %c | %c | %c \n",game[2][0],game[2][1],game[2][2]);
				printf("\n");
			}else{

				if(take_turns){
					take_turns = false;
				}else{
					take_turns = true;
				};
			}

		}
		//循环_1,是否开始新游戏
		if(feof(stdin) || ferror(stdin)){
			break;
		}
		while((c = getchar()) != '\n' && c != EOF);
		printf("是否开始新游戏?(y/n)");
		scanf("%c",&another_game);
	}while(toupper(another_game)=='Y');
	//结束
	return 0;
}

附上ASCII码表自用~~~
