我在TC下编的绘制特殊线的程序怎么在linux下成功运行?那个graphics.h是在不会改 那位帮忙把我改改 能再linux下运行
现在我把我的代码贴进来
# include "graphics.h"
# include "math.h"
# include "conio.h"
# define PATH "d:\\tc"
# define PI 3.1415926535
main()
{
int gdriver=VGA;
int gmode = VGAHI;
double a=0,b;
int x0=340,y0=240,radius=100,i,x,y;
initgraph(&gdriver,&gmode,PATH);
setcolor(2);
setlinestyle(0,0,0);
for(i=0;i<6;i++,a+=60)
{ b=a*PI/180;
x=x0+radius*cos(b);
y=y0+radius*sin(b);

arc(x,y,120-i*60,240-i*60,radius);

}
getch();
closegraph();
}
各位帮帮忙

[解决办法]
linux下的图形库多得很:SDL,gtk+,qt,iup,Xlib,不一定要全屏下实现的.
如果要跨平台,最好选一个通用的库.
[解决办法]
珍惜生命，远离TC及相关过于陈旧的书籍。
[解决办法]
我让你用TC……
Linux下的绘图库可以看看Cairo，跨平台的。
[解决办法]
在cygwin X环境下编译通过.使用Xlib库,编译命令:gcc prog.c -lX11
相信在linux X环境下没问题.修改的别人的代码

[解决办法]
 XDrawArc()的后6个参数分别是:外切方框的左上角的X值,Y值,外切框的宽,高,弧的起始度*64,相对要画的度数*64(不是结束的度数),这个函数跟TC的那个画法不一样.
