Hi,
I have to write a program, which will identify circles intersecting. If they are intersecting, move them horizontaly so that they cant intersect. I have n no. of circles in one plane, with origin & radius please help
Thanks

Basically, you need to find the distance between the two centers of circle.
int  x1,y1,x2,y2; int  r1,r2; x1=0;y1=0;r1=1; x2=3;y2=3;r2=2; double distancebetweencirclecenters=Math.Sqrt(Math.Pow((x1-x2),2)+Math.Pow((y1-y2),2)); if (Math.Abs(r1-r2) { Console.WriteLine( "Intersects" ); }     Please mark it as an answer if it addresses the issue.
