Assign argument function to class member

Vote count:

0

I have a class that contains a pointer to function as its member as follows:

class demo{
    void (*fn_ptr) (int) = NULL;        
    void AssignPtr(void (*fptr)(int))
    {
      *fn_ptr = *fptr;
    }
};

And I get error:

error: cannot convert ‘void(int)’ to ‘void(int)’ in assignment
