C++ Parent class calling a child virtual function

Question

I want a pure virtual parent class to call a child implementation of a function like so:

class parent
{
  public:
    void Read() { //read stuff }
    virtual vo         


        

Answer 1

Will work in general, but not for calls within the constructor of the pure virtual base class. At the time the base class in constructed, the sub-class override doesn't exist, so you can't call it. As long as you call it once the entire object is constructed, it should work.
