public:
Circle(double r = 1.0) : radius(r) {} //this part is what i dont understand

Jump to PostThat line is the constructor. It says to use a default value of 1.0 if nothing is passed. If something is passed, the
: radius(r)sets the member variable 'radius' to the value of 'r'. This is called an 'initializer list'.Dave
