Question

Create a class Hugelnteger that uses a 40-element array of digits to store integers as large as 40 digits each. Overload the equality (==) operator Overload the add (+)operator Overload the multiply (*) operator (extra bonus)
please do this C++ question asap

Answer 1

Code for Operator Overloading :

#include <iostream>

using namespace std;

class HugeInteger {
  
double s;
public:
void getnum(double str)
{
this->s=str;
}
void operator==(HugeInteger); // for ==
void operator+(HugeInteger); // for +
void operator*(HugeInteger); // for *
};

void HugeInteger::operator==(HugeInteger ob)
{
if(s==ob.s)
cout<<"\nIntegers are Equal";
else
cout<<"\nIntegers are not Equal";
}

void HugeInteger::operator+(HugeInteger ob)
{
HugeInteger sum;
sum.s=s+ob.s;

printf("The Sum of Integers is %f",sum.s);
}

void HugeInteger::operator*(HugeInteger ob)
{
HugeInteger mul;
mul.s=s*ob.s;

printf("The MUltiplication of Integers is %f",mul.s);
  
}

int main()
{
  
HugeInteger ob, ob1;
double num1, num2;
  

cout<<"Enter First number:";
cin>>num1;

ob.getnum(num1);

cout<<"\nEnter Second Number:";
cin>>num1;

ob1.getnum(num2);

ob==ob1; // Overloading ==
ob+ob1; //Overloading +

ob*ob1; //Overloading *

return 0;
}

Output:

sh-4.2$ main Enter First number:7 Enter Second Number:8 Integers are not Equal
