what is worng with this code

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
//#include <conio>

int main(void)
   /* request auto detection */
   int gdriver = DETECT, gmode, errorcode;
   int midx, midy;
   int radius = 100;

   /* initialize graphics and local variables */
   initgraph(&gdriver, &gmode, "C:\\Dev-c++\\include\\graphics.h");

   /* read result of initialization */
   errorcode = graphresult();
   if (errorcode != grOk)  /* an error occurred */
      printf("Graphics error: %s\n", grapherrormsg(errorcode));
      printf("Press any key to halt:");
      exit(1); /* terminate with an error code */

   midx = getmaxx() / 2;
   midy = getmaxy() / 2;

   /* draw the circle */
   circle(midx, midy, radius);

   /* clean up */
   return 0;

It shows the following:

[linker error] undefined referense to initgraph(int*,int*,char*)
[linker error] undefined referense to getmaxy()
[linker error] undefined referense to getmaxy()
[linker error] undefined referense to grapherrormsg(int)

graphics.h requires a specific library that is only found on Borland compilers (I don't think the newer Borland products even have it anymore). Look up WinBGIm as a possible alternative (however, it too is quite outdated).

Yes I downloaded that liabrary. The program shows these errors having this liabrary.
Please give me the solution .
