How can we improve the following program to do the same thing OOP using polymorphism.
float area (float);
float area(float,float);
float area(float r)
{
return 3.1416 * r;
}
float area(float l, float w)
{
return l*w;
}
main()
{
float rad,l,w;
coutrad;
cout

I am having difficulty getting my head around this concept.

class Cat {
String whatAmI() {

String isKickedBy(Kitten k) { return “Ouch!”; }
}
Cat bob = new NinjaKitten();
System.out.println(“Bob: ” + bob.whatAmI());
My question is what is bob’s static type and what is his dynamic type?
