Question

I have two classes, let’s say DerivedOne and DerivedTwo, derived from a base class Base.

Assuming I have these:

DerivedOne d1;
DerivedTwo d2;

when I compare d1 and d2, I’d like d1 to always be smaller, in other words an object of DerivedOne should have a higher priority than an object of DerivedTwo. What is the best/nicest way to do that?

Answer 1

In the super class declare a variable as priority.

And in the subclasses constructor, initialize that.

class A
{
int priority;
}

class Derived1
{
 Derived1()
 {
  priority=1;
 }
}


class Derived2
{
Derived2()
{
priority=0;
}
}
