源程序如下：
#include<stdio.h>
#include<graphics.h>
int main(void)
{
int gdriver,gmode;
gdriver=DETECT;
initgraph(&gdriver,&gmode,"");
setcolor(12);
settextstyle(4,0,8);
outtextxy(100,100,"game over");
getch();
setusercharsize(2,1,4,1);
setcolor(15);
settextstyle(2,0,4);
outtextxy(200,200,"game over");
getch();
setusercharsize(4,1,1,1);
settextstyle(3,0,0);
outtextxy(0,300,"game over");
getch();
closegraph();
return 0;
}
程序本意是想将第二个game over水平放大两倍，垂直放到四倍输出，但是结果输出第二个game over却是最原始大小，为什么呢？难道跟起始坐标（200，200）有关？
