[C++知识库]C语言三子棋小游戏代码实现

思维导图

头文件代码实现：

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#define ROW 3
#define COL 3
void InitBroad(char board[ROW][COL], int row, int col);//声明初始化棋盘为空格；
void DispalyBoard(char board[ROW][COL], int row, int col);//声明打印棋盘
void play_move(char board, int row, int col);//声明玩家下棋
void computer_move(char board[ROW][COL], int row, int col);//声明电脑下棋
char is_win(char board[ROW][COL], int row, int col);//判断胜负

游戏功能代码实现：

					printf("|");
			}
			printf("\n");
		}
		
	}
}
void play_move(char board[ROW][COL], int row, int col)//玩家移动
{
	int x = 0;
	int y = 0;
	printf("玩家下棋\n");
	while (1)
	{

		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{

			}
		}

		{
			printf("坐标非法，请重新输入\n");
		}
	}
}

int if_full(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for(i=0;i<row;i++)
	{
		int j = 0;
		for (j = 0;j < col;j++)
		{
			if (board[i][j] == ' ')
			{
				return 0;
			}
		}
	}
	return 0;
}

		if (board[x][y] == ' ')
		{

			break;
		}
    }

}

char is_win(char board[ROW][COL], int row, int col)
{
	int i = 0;
	//判断行
	for (i = 0;i < row;i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
		{

	}

		{

		}
		//继续

}

主体测试代码实现：

#include<time.h>
#include<stdlib.h>
void menu()
{
	printf("***********************\n");

	printf("********2.exit*********\n");
	printf("***********************\n");
}
void game()
{
	char ret = 0;
	//存放下棋的数据
	char board[ROW][COL] = { 0 };
	//初始化棋盘为空格；
	InitBroad(board, ROW, COL);
	//打印棋盘
	DispalyBoard(board, ROW, COL);
    while(1)
    {

	ret = is_win(board,ROW,COL);
	if (ret != 'C')
	{
		break;
	}

	}
	else
	{

	}
	DispalyBoard(board, ROW, COL);
}
//玩家赢返回'*'
//电脑赢返回“#”
//平局返回“Q"
//继续返回”C“
void test()

	do
