Question

Can you help with C++ please:

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. Write a program to test your class

There are 3 tabs: largeIntegers.cpp, largeIntegers.h, main.cpp

largeIntegers.h:

#ifndef LARGEINTEGER_H

#define LARGEINTEGER_H

#include <string>

class largeInteger {

private:

std::string number;

public:

largeInteger();

largeInteger(const std::string& value);

void setNumber(const std::string& value);

std::string getNumber() const;

void print() const;

largeInteger add(const largeInteger& other) const;

largeInteger subtract(const largeInteger& other) const;

largeInteger multiply(const largeInteger& other) const;

int compare(const largeInteger& other) const;

};

#endif

largeIntegers.cpp

#include "largeIntegers.h"

#include <iostream>

largeInteger::largeInteger() {

number = "0";

}

largeInteger::largeInteger(const std::string& value) {

setNumber(value);

}

void largeInteger::setNumber(const std::string& value) {

number = value;

}

std::string largeInteger::getNumber() const {

return number;

}

void largeInteger::print() const {

std::cout << number;

}

largeInteger largeInteger::add(const largeInteger& other) const {

// Perform addition here

largeInteger result;

// Implementation logic goes here

return result;

}

largeInteger largeInteger::subtract(const largeInteger& other) const {

// Perform subtraction here

largeInteger result;

// Implementation logic goes here

return result;

}

largeInteger largeInteger::multiply(const largeInteger& other) const {

// Perform multiplication here

largeInteger result;

// Implementation logic goes here

return result;

}

int largeInteger::compare(const largeInteger& other) const {

// Perform comparison here

// Return 0 if equal, -1 if this < other, 1 if this > other

int result = 0;

// Implementation logic goes here

return result;

}
