Please explain:

What has been achieved in terms of functionality, i.e what action/call or operation can I perform after dynamic casting?

Do Base*b or Derived* d have become more capable in any sense?

Please explain any thing that I is achieved after dynamic cast and was not possible otherwise.

code for ref:

#include

using namespace std;

class Base {

public:

virtual void print() {}

};

class Derived : public Base {

public:

void print2(){

cout

}

};

int main() {

Base* b = new Derived;

Derived* d = dynamic_cast (b);

if (d != NULL) {

cout

}

else {

cout

}

return 0;

}
