Mutable storage class is applicable to only class data members. If a data member of a class is declared as mutable, then it can be modified by an object which is declared as constant.

An array is a contiguous chunk of memory with a fixed size whereas a list is typically implemented as individual elements linked to each other via pointers and does not have a fixed size. Once an array is initialized, it cannot be resized, and it uses a fixed amount of memory regardless of how much stuff you put in it. Since a list is a collection of individual chunks of memory that are dynamically allocated, the space required to store a list is directly related to the number of elements in it.

When a method is declared as abstract/virtual method in a base class and which is overridden in a base class. If we create a variable of a type of a base class and assign an object of a derived class to it, it will be decided at a run time, which implementation of a method is to be called.
This is known as Pure-Polymorphism or Late-Binding.

This pointer is called current object of the class.

Copy constructor is used to declare and initialize an object from another object.
For example, the statement
Integer I2(I1);
Would define the object I2 and at the same time initialize it to the values of I1. another form of this statement is integer I2=I1;
The process of initializing through a copy constructor is known as copy initialization. A copy constructor takes a reference to an object of the same class as itself as an argument.

USED TO CONVERT HIERACHICAL STRUCTURE TO THE FLAT STRUCTURE. IT IS USED TO JOIN A TABLE ITSELF AS LIKE IF THAT IS THE SECOND TABLE
