## 代码如下： ##

#include <graphics.h>//图形库 
    #include <stdlib.h>
    #include <string.h>
    #include <mmsystem.h>//多媒体库 mciSendSting
    #pragma comment(lib,"winmm.lib")
    
    //封装按钮属性
    typedef struct BUTTON
    { 
    	int x, y;
    	int xx, yy;
    	COLORREF color;
    	char* buttonstr;
    }*PBTN;//按钮指针
    
    //1、创建按钮
    PBTN creatButton(int x, int y, int xx, int yy,const char* str)
    { 
    	PBTN button = (PBTN)malloc(sizeof(PBTN));
    	button->x = x;
    	button->y = y;
    	button->xx = xx;
    	button->yy = yy;
    	button->buttonstr = (char*)malloc(sizeof(char));//?
    	strcpy(button->buttonstr, str);
    
    	return button;
    }
    //2、绘制按钮图形
    void drawButton(PBTN button)
    { 
    	setfillcolor(button->color);
    	setlinecolor(BLACK);
    	fillrectangle(button->x, button->y,button->xx, button->yy);

    }
    //3、判断鼠标是否在按钮范围内
    int isInButton(PBTN button,MOUSEMSG m)
    { 
    	if (button->x <= m.x && button->xx >= m.x && button->y <= m.y && button->yy >= m.y)//判断范围
    	{ 
    		return 1;
    	}
    	else
    		return 0;
    }
    //4、鼠标移动 显示效果
    void mouseMove(PBTN button,MOUSEMSG m)

    		button->color = RED;//鼠标在按钮范围内 红色
    	}

    }
    //5、鼠标是否点击按钮
    int clickButton(PBTN button,MOUSEMSG m)
    { 
    	if (isInButton(button, m))
    	{ 
    		if (m.uMsg == WM_LBUTTONDOWN)//4、鼠标是否左键按下

    	}

    	while (1)
    	{
