Question

class Parent {
public:
    void func1(); // Complete meaningful definition in parent given.

    virtual HRESULT func2()=0;  // Bcoz of this function Parent class is abstract. 
};


class Child: public Parent {
public:
    void func1(); // Different definition in child.
};

Is this possible in C++ ? I am overriding func1() which is NOT virtual and it already has a definition in parent abstract class.

[assuming here Child extends Parent, unlike what the code snap shows]

Yes it is possible [it is called hiding] – but you will not get a dynamic dispatch behavior.

The static type will define which method will be invoked, and not the dynamic type.

For example:

Parent* p = new Child;
p->func1();

Will invoke Parent::func1()

while:

Child* c = new Child;
c->func1();

Will invoke Child::func1()
