    What are the difference between an ARRAY and a LIST?
    Answer:

    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.

    What is polymorphism and Pure-Polymorphism?
    Answer:

    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.

    What is Copy Constructor? Write a program using it.
    Answer:

    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.
