Thus size should be the size of base class data members + size of derived class data members.Let's check the below code and the output.ExampleIn the above structure, we find that the size is 24 Bytes though the same data members have been used. This is due to the chang...
So, your question equals "Can we instance a derived class before base class?". 1. Try to answer this question instead, from your knowledge of class inheritance. 2. Write some code doing that and see what happens. 30th May 2022, 12:38 PM Emerson Prado + 1 Slick "Try it yoursel...
In this example, class Derived is derived from class Base. Because Derived inherits functions and variables from Base, you may assume that the members of Base are copied into Derived. However, this is not true. Instead, we can consider Derived as a two part class: one part Derived, and ...
