What is meant by instancing a class?

The class can be considered a template to create objects. When you create an object, you create it on the basis of the specified class - the object is an instance of the class, and the act of creating the object is also known as "instantiating" the class.


What is the difference between a class method and object in object-oriented C?

Class methods are the member functions that act upon member variables. An object is an instance of a class. C does not support object-oriented programming, but C++ does.


What is insulation in transformer?

Depending on the size of the transformer, several different types of insulator are used. These include varnishes, plastics, paper, and fabrics (to insulate the windings), wood (spacers), and oil. Transformer oil improves the insulation value of paper, fabrics, and wood when absorbed by them. The oil has a secondary purpose, which is to cool the transformer.


Is object of superclass created when object of derived class is created?

Not as a separate instance. The derived class instance can be used anywhere a superclass instance is expected, so it is an instance of the superclass in that respect, and a superclass constructor will be called at creation time. However, it will always act like an instance of the derived class, even if it is explicitly cast to the superclass. So overridden methods will always call the derived class method, regardless of how an outside caller refers to the instance.
