    Change D to a struct.

    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.

    }; // this closing brace and semicolon was entirely missing
