Question

I have seen some solutions to this problem in Bartleby's library that make no sense to me. I am learning C++, more specifically working with dynamic integers and have become confused with what has been provided previously by others.

Using dynamic integers, can I get help with creating a class named 'largeIntegers' so that an object of this class can store an integer of any number of digits. If I could get help with setting up operations to add, subtract, multiply, and compare integers stored in two objects. Also, if someone could explain and help myself create constructors to properly initialize objects and functions to set, retrieve, and print the values of objects.

There are three files I am working with:

main.cpp, largeIntegers.h, and largeIntegers.cpp

largeIntegers.cpp

#include <iostream>

using namespace std;

largeIntegers.h

//Specification file largeIntegers.h

#ifndef H_largeIntegers

#define H_largeIntegers

#include <iostream>

using namespace std;

#endif

main

#include <iostream>

using namespace std;

int main() {

return 0;

}

Chapter 12, Problem 4PE
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 largelntegers 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.

10class largeIntegers {
11private:
12    string num;  // To simplify, we're storing the number as a string
13    bool isNegative;

15public:
16    largeIntegers();

20    string getNumber() const;
21    void print() const;
