三子棋C语言实现

用C语言写三子棋

1. 头文件

#define _CRT_SECURE_NO_WARNINGS

#include <stdio.h>
#include <stdlib.h>
//标识符定义
#define ROW 3
#define COL 3

//函数定义
//棋盘初始化
void init_board(char board[ROW][COL], int row, int col);
//打印棋盘
void display_board(char board[ROW][COL], int row, int col);
//玩家下棋
void player_game(char board[ROW][COL], int row, int col);
//电脑下棋
void comeputer_game(char board[ROW][COL], int row, int col);
//判断输赢
char is_win(char board[ROW][COL], int row, int col);

2. 游戏函数

 `#include "game.h"

//棋盘初始化
void init_board(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++) {
			board[i][j] = ' ';
		}
	}
}

//打印棋盘
void display_board(char board[ROW][COL], int row, int col) {
	int i = 0;
	int j = 0;
	int k = 0;
	for (i = 0; i < ROW; i++) {
		for (j = 0; j < COL; j++) {
			printf(" %c ",board[i][j]);
			if (j < COL - 1) {
				printf("|");
			}
		}
		printf("\n");
		if (i < ROW - 1) {
			for (k = 0; k < COL; k++) {
				printf("---");
				if (k < COL - 1) {
					printf("|");
				}
			}				
		}
		printf("\n");
	}
}

//玩家下棋
void player_game(char board[ROW][COL], int row, int col) {
	int x = 0;
	int y = 0;
	while (1)
	{
		printf("请输入你要落子的坐标>:");
		scanf("%d %d", &x, &y);
		if (x <= row && y <= col && x >= 1 && y >= 1) {
			if (board[x - 1][y - 1] == ' ') {
				board[x - 1][y - 1] = '*';
				break;
			}
			else {
				printf("你输入的坐标被占用!\n");
			}
		}
		else {
			printf("你输入的坐标有误，请重新输入！\n");
		}
	}	
}

//电脑下棋
void comeputer_game(char board[ROW][COL], int row, int col) {
	while (1) {
		int x = rand() % row;
		int y = rand() % col;
		if (board[x][y] == ' ') {
			board[x][y] = '#';
			break;
		}
	}	
}

//判断输赢
//1.玩家赢返回*
//2.电脑赢返回#
//3.双方都不赢，棋盘没有位置平局返回p
//4.双方都不赢，棋盘还有位置继续下棋返回c
char is_win(char board[ROW][COL], int row, int col) {
	int x = 0;
	int y = 0;	 
	//判断行
	for (x = 0; x < row; x++) {
		if (board[x][0] == board[x][1] && board[x][1] == board[x][2] && board[x][1] != ' ') {
			return board[x][1];
		}		
	}
	//判断列
	for (y = 0; y < col; y++) {
		if (board[0][y] == board[1][y] && board[1][y] == board[2][y] && board[1][y] != ' ') {
			return board[1][y];
		}		
	}
	//判断对角线
	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[1][2] && board[1][1] != ' ') {
		return board[1][1];
	}
	//判断棋盘是否有空位
	for (x = 0; x < row; x++) {
		for (y = 0; y < col; y++) {
			if (board[x][y] == ' ') {
				return 'c';
			}
		}
	}
	return 'p';
}`

3. 游戏实现

#include "game.h"

//打印菜单
void menu() {
	printf("***************************\n");
	printf("********* 三 子 棋 ********\n");
	printf("********* 1. play  ********\n");
	printf("********* 0. exit  ********\n");
	printf("***************************\n");
}

void game() {
	char win = 0;
	//定义棋盘存储
	char board[ROW][COL];
	//棋盘初始化
	init_board(board, ROW, COL);
	//打印棋盘
	display_board(board, ROW, COL);
	while (1) {
		//玩家下棋
		player_game(board, ROW, COL);
		display_board(board, ROW, COL);
		//判断输赢
		win = is_win(board, ROW, COL);
		if (win != 'c') {
			break;
		}
		//电脑下棋
		comeputer_game(board, ROW, COL);
		display_board(board, ROW, COL);
		//判断输赢
		win = is_win(board, ROW, COL);
		if (win != 'c') {
			break;
		}
	}
	if (win == '*') {
		printf("恭喜玩家胜利！\n");
		display_board(board, ROW, COL);
		system("pause");
	}
	else if (win == '#') {
		printf("电脑胜利，继续加油哟！\n");
		display_board(board, ROW, COL);
		system("pause");
	}
	else {
		printf("平局\n");
		display_board(board, ROW, COL);
		system("pause");
	}

}  

int main(void) {
	
	int num = 0;
	srand((unsigned)time(NULL));
	do {
		//打印菜单
		menu();
		//选择菜单
		printf("请选择菜单>:");
		scanf("%d", &num);
		switch (num)
		{
		case 0:
			break;
		case 1:
			game();
			break;
		default:
			printf("你的选择错误，请重新选择！\n");
			system("pause");
			system("cls");
			break;
		}

	} while (num);
	

	system("pause");
	return 0;
}
