Explain protected derivation, C/C++ Programming

Assignment Help:

Protected derivation

In addition to doing private and public derivations, you may also do a protected derivation. In this situation :

 

  • The private members inherited from the base class are inaccessible to new member functions in the derived class.

   (this is exactly same as if a private or public derivation has occurred.)

  • The protected members inherited from the base class have protected access privilege.
  • The public members inherited from the base class have protected have protected access.

Therefore, the only difference among a public and a protected derivation is how the public members of the parent class are inherited. It is unlikely that you will ever have occasion to do this type of derivation.
