In C++, the compiler creates a default constructor if we don’t define our own constructor.6 Oca 2022

Read moreWhy and when do we use inheritance in C++?
Why and When to use Inheritance in C++? We use inheritance in C++ for the reusability of code from the existing class . C++ Strongly supports the concept of reusability. Reusability is yet another important feature of OOP(Object Oriented Programming).8 Ara 2021
Read moreWhat is inheritance C++?
Inheritance is a mechanism of reusing and extending existing classes without modifying them, thus producing hierarchical relationships between them . Inheritance is almost like embedding an object into a class. Suppose that you declare an object x of class A in the class definition of B .
