The problem is currently, in the first example the default constructor for the Parent is being called. What if we don’t want that to happen? What if we won’t to have some custom code run, so we want a specific Constructor of the Parent to be executed. The solution to this, is to...

C++ Practice Tests have the best questions to make you understand the topic well. After each section you study, give the related Practice test.
when you supply a constructor C# does not provide a default constructor In this case, we have to explicitly maintain the ‘chain’ Another scenario for this error is when you define an explicit constructor with zero parameters and mark it as private The compiler will raise an error in this ...
