Note that I'm not a native English speaker, and I will thank you if you'll use simple English in your answers…

class A
{
public:
virtual int hello(A a);
};
class B : public A
{
public:
int hello(B b){ bla bla };
};
So, A it's an abstract class.
1)In the class B, I'm defining a method that its suppose overrides the A class. But the parameter it's slightly different. I'm…

The classe prototypes permit to have Timer objects, each with their waiting times, Repeat objects that group Timer and other Repeat objects, and a Schedule class, just for holding a whole construction or Timers and Repeat instances…

In C++, there are 2 types of Polymorphism:
Object Polymorphism
Function Polymorphism
Function polymorphism is exactly the same thing as method or function overloading i.e. We use the same method names with different parameters and return types. Now the question is why do we have this fancy name…
