i am trying to a c++ program that will determine if two circles intersect each other. the input will be <x,y> coordinates for the center of each circle followed by the radius of each circle. the output will state whether the circles overlap, don't overlap or tangential(touch each other at one common point)
what have you got so far?
I can help you with math:
if sqrt( (x1 - x2)^2 + (y1 - y2)^2) > r1 + r2 => circles does not intersects
if --//-- < r1 + r2 => circles does intersects
if --//-- = r1 + r2 => circles are tangential
