C++ Resolving the diamond problem

Question

Couldn\'t the diamond problem be resolved just by using the first inherited declaration found? I mean,

public class A {
    public virtual int getInt();
};

public cl         


        

Answer 1

This is not a diamond problem. C++ compiler is specific about all its syntax, if there is any ambiguity it will always throw error.

Here your A::getInt(), B::getInt() and C::getInt() are ambiguous when you call simply d.getInt().

Edit:

In your edited question, still compiler doesn't evaluate from the inheritance, because some programmers may really need to have different copies of A==> 1st via class B and 2nd via class C. Note that so called diamond problem is a problem characterized by humans. For C++ compiler, it's just one more pattern.

In C++ philosophy, you are not restricted to only one paradigm or pattern. You can choose to have multiple inheritance of your choice.
