Accessing class members on a NULL pointer

Question

I was experimenting with C++ and found the below code as very strange.

class Foo{
public:
    virtual void say_virtual_hi(){
        std::cout << \"Vi         


        

Answer 1

The call to say_hi is statically bound. So the computer actually simply does a standard call to a function. The function doesn't use any fields, so there is no problem.

The call to virtual_say_hi is dynamically bound, so the processor goes to the virtual table, and since there is no virtual table there, it jumps somewhere random and crashes the program.
