想问下char savepattern[8];是什么意思？好像程序中没有用到。。隐含什么意义?
代码:
#include <graphics.h>
main()
{
   int graphdriver=VGA,graphmode=VGAHI;
   struct fillsettingstype save;
   char savepattern[8];
   int d[]={420,20,330,45,330,145,420,120,510,145,510,55,420,20};
   initgraph(&graphdriver,&graphmode,"");
   getfillsettings(&save);
   setfillstyle(3,BLUE);
   bar3d(100,50,150,120,30,1);
   setfillstyle(HATCH_FILL,RED);
   bar3d(200,50,250,120,30,0);
   setfillstyle(1,GREEN);
   sector(200,300,0,250,100,40);
   setfillstyle(1,LIGHTRED);
   fillellipse(420,300,100,40);
   fillellipse(420,300,100,40);
   setfillstyle(1,5);
   fillpoly(7,d);
   getch();
   setfillstyle(save.pattern,save.color);
   closegraph();
}

没用上原义要保存颜色,样式.
这在setfillstyle 和结构 fillsettingstype 中已定义.

#include <graphics.h>
main()
{
int i,graphdriver,graphmode,size,page;
char s[30];
graphdriver=DETECT;
initgraph(&graphdriver,&graphmode,"");
cleardevice();
settextstyle(DEFAULT_FONT,HORIZ_DIR,2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,20,"Defaut font");
settextstyle(TRIPLEX_FONT,HORIZ_DIR, 2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,50,"Triplex font");
settextstyle(SMALL_FONT,HORIZ_DIR, 2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,80,"Smallfont");
settextstyle(SANS_SERIF_FONT,HORIZ_DIR,2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,110,"Sans serif font");
settextstyle(GOTHIC_FONT,HORIZ_DIR, 2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,140,"gothic font");
getch();
closegraph();
}这个呢.又怎么解释?

还有这个..我觉得这个有问题...
#include <graphics.h>
main()
41
{
int graphdriver=VGA,graphmode=VGAHI;
struct fillsettingstype save;
char savepattern[8];
char gray50[]={0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x81};
initgraph(&graphdriver,&graphmode,"");
getfillsettings(&save); /* 得到初始化时填充模式 */
if(save.pattern != USER_FILL )
setfillstyle(3,BLUE);
bar(0,0,100,100);
setfillstyle(HATCH_FILL,RED);
pieslice(200,300,90,180,90);
setfillpattern(gray50,YELLOW); /* 设定用户自定义图模进行填充*/
bar(100,100,200,200);
if(save.pattern==USER_FILL)
setfillpattern(savepattern,save.color);
else
setfillpattern(savepattern, save.color); /* 恢复原来的填充模式 */
getch();
closegraph();
}

/* 你这话什么意思,考我那?*/
#include <graphics.h>
main()
{
int i,graphdriver,graphmode,size,page;
char s[30];
graphdriver=DETECT; /*自动选取系统最大支持模式*/
initgraph(&graphdriver,&graphmode,"");
cleardevice(); /*清屏*/
settextstyle(DEFAULT_FONT,HORIZ_DIR,2); /*设置文本样式*/
settextjustify(LEFT_TEXT,0);
outtextxy(220,20,"Defaut font");  /*跳到指定点输出*/
settextstyle(TRIPLEX_FONT,HORIZ_DIR, 2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,50,"Triplex font");
settextstyle(SMALL_FONT,HORIZ_DIR, 2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,80,"Smallfont");
settextstyle(SANS_SERIF_FONT,HORIZ_DIR,2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,110,"Sans serif font");
settextstyle(GOTHIC_FONT,HORIZ_DIR, 2);
settextjustify(LEFT_TEXT,0);
outtextxy(220,140,"gothic font");
getch();  /*等待任意键*/
closegraph();/*关闭图形驱动*/
}

/*那就请你也解释,解释,这个吧*/ /*我好长点知识*/

兄弟呀,态度!

如果 pattern 没有记错的话,它应是,图案,式样*/
要做到见名知意,应该没错.

savepattern这个根本就没用上，你可以把这行注掉了。应该是作者废弃该变量之后忘记删了。

不好意思..
我没有说你什么哇..
如有什么得罪的地方.多多包涵..

不好意思..
我只是想你帮我看看这几个程序有中的不同之处..
没有什么意图哇...
