Question

Are array of pointers to different types possible in c++? with example please)

Answer 1

Usually if you want to have a collection of different "types" of pointers, you implement it in a way where they derive off a base class/interface and store a pointer to that base. Then through polymorphism you can have them behave as different types.

class Base
{
public:
    virtual void doSomething() = 0;
};

class A : public Base
{
    void doSomething() { cout << "A\n"; } 
};

class B : public Base
{
    void doSomething() { cout << "B\n"; } 
};

std::vector<Base*> pointers;
pointers.push_back(new A);
pointers.push_back(new B);
