Polymorphism is an OOPs concept in computer science that allows objects of different types to be treated as objects of a common type. Read On!
The two types of polymorphism are : Compile time (or Static) polymorphism In Compile time polymorphism, static binding is performed. In static binding, the compiler decides the selection of appropriate function to be called in response to the compile time call. It is because all the addressinfor...

The capabilities (i.e., the public functions) offered by the external applications are provided as pure virtual functions in the abstract base class. The implementations of these pure virtual functions are provided in the derived classes that correspond to the specific types of the application. Thi...

7) How can we implement function overloading in C++? Using types of different arguments. Using number of arguments. Using order of arguments. All of the above Options: A and B B and C A and C D Answer 8) To implement function overloading we need to include "funover.h" header...
“Proxy” is a modern C++ library that helps you use polymorphism (a way to use different types of objects interchangeably) without needing inheritance. “Proxy” was created by Microsoft engineers and has been used in the Windows operating system since 2022. For many years, using inheritance wa...
Base class In the above example, although, the object is of Derived class, still Base class's method is called. This happens due to Early Binding. Compiler on seeingBase class's pointer, set call to Base class'sshow()function, without knowing the actual object type. ...
The full implementation of the example above could be found in our integration tests. In this example, there are 3 return statements in different branches and the return types are also different. Lifetime management with inheritance-based polymorphism is error-prone and inflexible, while proxy allow...
