Question

Programming Exercise 11 in Chapter 8 explains how to add large integers using arrays. However, in that exercise, the program could add only integers of, at most, 20 digits. This chapter explains how to work with
dynamic integers. Design a class named largeIntegers such that an
object of this class can store an integer of any number of digits. Add
operations to add, subtract, multiply, and compare integers stored in
two objects. Also add constructors to properly initialize objects and
functions to set, retrieve, and print the values of objects.

*Exercise eleven is pictured below

### Adding Large Integers

In C++, the largest `int` value is 2,147,483,647. Therefore, an integer larger than this cannot be stored and processed as an integer. Similarly, if the sum or product of two positive integers exceeds 2,147,483,647, the result will be incorrect.

#### Storing Large Integers
One effective method to handle large integers is to store each individual digit of the number in an array.

#### Programming Task
Write a program to input two positive integers, each having at most 20 digits, and output their sum. If the sum has more than 20 digits, the program should return an appropriate message.

#### Program Requirements
1. The program should include a function to read and store a number into an array.
2. Another function should be used to output the sum of the numbers.

#### Hint
- Read numbers as strings and store the digits of the number in reverse order.
