pls modify for me

plz help me guyzz....pls modify this....this code should have two balls and wen they bump each other they go in separate ways....
i need it as soon as possible guyzz help...thanx

Code:

#include<conio.h>
#include<graphics.h>
#include<dos.h>
#include<stdlib.h>
main()
{
 int gdriver=DETECT, gmode, r, col, row, pathx, pathy,speed;
 int forecolor, bkcolor, linecolor;
 initgraph(&gdriver,&gmode,"C:\\TCLITE\\BGI");
 randomize();
 r=random(40)+10;
 col=r+random(640-2*r);
 row=r+random(480-2*r);
 forecolor=random(14)+1;
 bkcolor=random(14)+1;
 linecolor=random(14)+1;
 speed=random(5)+1;
 pathx=(pathy=speed);
 setbkcolor(bkcolor);
 while (!kbhit())
 {
	  col+=pathx;
	  row+=pathy;
	  setcolor(linecolor);
	  circle(col,row,r);
	  setfillstyle(SOLID_FILL,forecolor);
	  floodfill(col,row,linecolor);
	  delay(10);
	  setfillstyle(SOLID_FILL,bkcolor);
	  floodfill(col,row,linecolor);
	  setcolor(bkcolor);
	  circle(col,row,r);
	  col+=pathx;
	  row+=pathy;
	  if (col+r>640) pathx=-(speed);
	  if (row+r>480) pathy=-(speed);
	  if (col-r<0) pathx=speed;
	  if (row-r<0) pathy=speed;
 }
 closegraph();

}

Yeah, I'll be sure and get right on that.

Oh, okay, Quzah, you got it. I was going to drop everything I'm doing (including my current proejct with an April 3rd deadline) and handle this.... I owe you one!
