Sure.
You declare a class as follows: class MyClass { //some stuff here... } You create an object as follows: MyClass object; This is how you create classes and objects in C++.
An object is simply an instance of a class. #include<iostream> class my_object {}; int main() { my_object X; // instantiate an instance of the class my_object, identified as X. }
You implement inheritance by deriving a new class of object from an existing class of object. The existing class is known as the base class of the derived class.Classes declared final cannot be used as bases classes and classes without a virtual destructor (or a virtual destructor override) cannot be used as polymorphic base classes.
No. You can declare a dynamic array without specifying a length, but in order to physically instantiate (either by using malloc or by using object-oriented construction) you must provide a length.
No. C is not object-oriented, it is a procedural language.C++, while object-oriented, is not purelyobject-oriented. One of the requirements for a pure object-oriented language is that everything is an object. C++ still has primitive data types (int, long, double, etc.), and so is not purely object-oriented.
An object is simply an instance of a class.
An object in C++ is an instance of a C++ class.
To expose an interface to the class members. Without an interface of some kind, an object would be useless.

B. Class.

-define class with necessary data member & member function. -create object of that class. -communication.

Instantiation of a class literally means creating an instance of a class. This is the process of allocating memory for an object that you can use in your program.
