Change D to a struct.

Code:

class D: B {}; 

to

class struct B {};

??

We're not human compilers. At least make an honest effort before asking us questions. What you posted has a number of mistakes and issues, and it indicates you have no clue what you're doing. Don't dump garbage code at us without giving us anything to go on.

Here's a free pass:

Code:

#include <iostream>

class B
{
	public: 
		virtual void display() 
		{
			std::cout << "No function display defined in this class\n"; 
		}
};
class D : public B
{
	
};

int main() 
{ 
	D d; 
	d.display(); 
}

Go learn to code for real, and make sure you're not lazy about it. We're willing to help, of course, but if you don't have a good foundation in something, we can't point you in the right direction. That requires you to learn.

When code is indented properly, all things become clear.
