c 语言同心圆调试

/* draw circies */
#include <graphics.h>
void  main ()
{
 int b ;
 int gdriver=DETECT ,gmode ;
 initgraph (&gdriver ,&gmode, “c:\TC201E\TIB”) ;
 cleardevice () ;
 printf(“\n\n\n   This program show the circle graph .\n”) ;
 for (b=10;b<=140;b+=10)
 circle (320,240,b);
 getch ();
 closegraph () ;
 
 
 }

c:\TC201E\TIB  此处的路径该怎么写呢？
