Question: 1 / 565

How are constructors called in a class hierarchy?

From derived to base

In parallel

Randomly

From base to derived

Constructors are called from base to derived in a class hierarchy because in object-oriented programming, derived classes inherit from base classes. In order for a child class to have access to the parent class's properties and methods, the parent class's constructor must be called first in order to initialize the parent class's members. Therefore, constructors must be called from base to derived in order for the inheritance relationship to function properly. This means that the base class's constructor must always be called before the derived class's constructor. Options A, B, and C are incorrect because they do not follow this logical sequence and would result in potential errors or issues with the class hierarchy.
