An array can be used to store large integer sone digit at a time. For example, the integer 1234 could be stored in the array a by setting a[0] to 1, a[1] to 2, a[2] to 3, and a[3] to 4. However, for this project, you might find it easier to store the digits backward, that is, place 4 in a[0], place 3 in a[1], place 2 in a[2], and place 1 in a[3].Design, implement and test a class in which each object is a large integer with each digit stored in a separate element of an array. Youll also need a private member variable to keep track of the sign of the integer (perhaps a boolean variable). The number of digits may grow as the program runs, so the class must use a dynamic array. Discuss and implement other appropriate operators for this class.

You should be able to initialize the class using a default constructor (no parameters) AND by giving a number (a non-default constructor).

You should be able to append digits (e.g. if the number stored is 123, you can add more digits.. 45 and the new number is 12345).

USE DYNAMIC MEMORY.
