C语言实现三子棋

     C语言实现三子棋，简单实现人机对战操作，代码包括，显示棋盘和刷新操作，用户输入棋盘坐标，来实现下棋操作，通过随机生成来实现与电脑对战，通过三子连珠的情况判断游戏结束。

    通过完成三子棋代码，熟练掌握和运用二维数组，明白数组存储时的模型，加深数组传参时的条件以及数组如何传参。加强头文件和函数的运用。

 

 头文件game.h声明

#ifndef __GAME_H__
#define __GAME_H__

#include<stdio.h>
#include<Windows.h>
#pragma warning(disable : 4996)

#define ROW 3   //定义行列
#define COL 3

void Game();
char Judge(char* broad, int i, int j);
void PlayerMove(char* broad, int i, int j);
void ComputerMove(char* broad, int i, int j);
void ShowBoard(char* broad, int i, int j);
int roll();


#endif

 

 具体头文件内容，函数的定义 game.c

#include "game.h"



char Judge(char board[][COL], int row, int col)
{
	int i = 0;
	for (; i < row; i++){
		if (board[i][0] != ' ' && board[i][0] == board[i][1] && \
			board[i][1] == board[i][2]){
			return board[i][0];
		}
	}
	for (i = 0; i < col; i++){
		if (board[0][i] != ' ' && board[0][i] == board[1][i] && \
			board[1][i] == board[2][i]){
			return board[0][i];
		}
	}
	if (board[0][0] != ' ' &&board[0][0] == board[1][1] && \
		board[1][1] == board[2][2]){
		return board[1][1];
	}
	if (board[0][2] != ' ' &&board[0][2] == board[1][1] && \
		board[1][1] == board[2][0]){
		return board[1][1];
	}
	for (i = 0; i < row; i++){
		int j = 0;
		for (; j < col; j++){
			if (board[i][j] == ' '){
				return 'N';
			}
		}
	}
	return 'E';
}

void InitBoard(char board[][COL], int row, int col){
	for (int i = 0; i < col; i++)
	for (int j = 0; j < row; j++)
		board[i][j] = ' ';
}

void Game()
{
	char result = '\0';
	char board[ROW][COL];
	InitBoard(board, ROW, COL); 
	ShowBoard(board, ROW, COL);
	srand((unsigned int)time(NULL));
	if (roll() == 1){
		while (1){
			PlayerMove(board, ROW, COL);
			ShowBoard(board, ROW, COL);
			result = Judge(board, ROW, COL);
			if (result != 'N'){
				break;
			}
			system("CLS");
			ComputerMove(board, ROW, COL);
			ShowBoard(board, ROW, COL);
			result = Judge(board, ROW, COL);
			if (result != 'N'){
				break;
			}
		}
	}
	else{

		}
	}
	switch (result){
	case 'X': //you win
		break;
	case 'O': //computer win
		break;
	case 'E': //Equal
		break;
	default:
		printf("bug?!\n");
		break;
	}

	//memset(board, ' ', sizeof(board));
	printf("再来一把？\n");
}

void PlayerMove(char broad[][COL], int row, int col){
	printf("输入X坐标与Y坐标");
	int x = 0;
	int y = 0;
	while (1){
		scanf("%d%d", &x, &y);
		if (x >= row || x < 0 || y >= col || y < 0)
			printf("输入有误，范围在（1，3）之间");
		else if (broad[x][y] != ' ')
			printf("输入的位置已被占用,请重新输入");
		else{
			broad[x][y] = 'X';
			break;
		}
	}
	


}

void ShowBoard(char board[][COL], int raw, int col){
	for (int i = 0; i < col; i++){
		for (int j = 0; j < raw; j++)
			printf("| %c ", board[i][j]);
		printf("|\n");
		printf("----------------\n");
	}
}

int GetRandom(int start, int end)
{
	return rand() % (end - start + 1) + start;
}
void ComputerMove(char board[][COL], int row, int col)
{
	while (1){
		int x = GetRandom(1, 3);
		int y = GetRandom(1, 3);
		if (board[x - 1][y - 1] == ' '){
			board[x - 1][y - 1] = 'O';
			break;
		}
	}
}

int roll(){
	int x = 0;
	printf("选择先手\n");
	printf("1.玩家先手    2.电脑先手\n");
	printf("请选择：");
	scanf("%d", &x);
	return x;
}

新增选择电脑或玩家先手的方法

int roll(){
	int x = 0;
	printf("选择先手\n");
	printf("1.玩家先手    2.电脑先手\n");
	printf("请选择：");
	scanf("%d", &x);
	return x;
}



//game（）函数中的判定 调换PLAYER和COMPUTER位置

if (roll() == 1){
		while (1){
			PlayerMove(board, ROW, COL);
			ShowBoard(board, ROW, COL);
			result = Judge(board, ROW, COL);
			if (result != 'N'){
				break;
			}
			system("CLS");
			ComputerMove(board, ROW, COL);
			ShowBoard(board, ROW, COL);
			result = Judge(board, ROW, COL);
			if (result != 'N'){
				break;
			}
		}
	}
	else{
		while (1){
			ComputerMove(board, ROW, COL);
			ShowBoard(board, ROW, COL);
			result = Judge(board, ROW, COL);
			if (result != 'N'){
				break;
			}
			PlayerMove(board, ROW, COL);
			ShowBoard(board, ROW, COL);
			system("CLS");
			result = Judge(board, ROW, COL);
			if (result != 'N'){
				break;
			}
		}

主函数，实现菜单方法

#include "game.h"


void Showmenu(){
	printf("#################################\n");
	printf("## 1. Play             2. Exit ##\n");
	printf("#################################\n");
	printf("Please Select: ");
}

int main()
{
	int select = 0;
	int quit = 0;
	while (!quit){
		Showmenu();
		scanf("%d", &select);
		switch (select){
		case 1:
			Game();
			break;
		case 2:
			printf("Bye bye!\n");
			quit = 1;
			break;
		default:
			printf("select error, try again!\n");
			break;
		}
	}
	system("pause");
	return 0;

}

 

 后续更新  优化判定算法，和电脑算法。
