Object Oriented Programming with C++, Second Edition

For Advanced Readers

1. In C++, we create objects in two different ways. In first method, we declare the object directly, meaning without using pointer. In second method, we first declare a pointer to an object and then create the object with new operator. We use that object by dereferencing the pointer. As far as classification (or behaviour) of polymorphism is concerned, we are interested in knowing how the object is referred in source code. It may be used with or without pointer. If we are using objects without pointers, it leads to compile time polymorphism. If we are using objects with pointer, it may be either compile time polymorphism or run time polymorphism.

2. While overriding virtual functions, we should ensure that the signature and ...
