DATA STRUCTURES & OTHER OBJECTS Using C++

Please provide header file[.h] , driver file,[.cpp] and main file [.cpp]

Please provide your code and screenshot of how your code ran.

An array can be used to store large integers one 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. You’ll 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 the +operator for this class.
