Question

Say if I have an interface with virtual methods, but one of the arguments are:

virtual void Delete(ParentClass *parentClass) = 0;

If I later implement this in child class

void Delete(ChildClass *childClass)
{
};

…why doesn’t this work as an implementation?

Answer 1

As the function prototype differs (one uses ParentClass and the other ChildClass) they are not the same functions. Instead the one with the ChildClass argument is overloading and not overriding the Delete function.
