Need help on operator overloading in c++

Question

Write a c++ program to overload '+' operator to find the sum of length of two given strings.

If S1 and S2 are strings then S1+S2 should give the sum of lengths of S1 and S2

Answer 1

Sum.h file:

#ifndef SUM_H
#define SUM_H
#include<iostream>
using namespace std;

class sum
{
   public:
       string s1;
       sum(string s1);
       int operator+(sum);
};

#endif // SUM_H

Sum.cpp file:

#include "sum.h"

sum::sum(string s1)
{
    this->s1=s1;
}
int sum::operator+(sum s)
{
    int n1=s1.length();
    int n2=s.s1.length();
    return n1+n2;
}

Main.cpp file:

#include <iostream>
#include <string>
#include "sum.h"
using namespace std;

int main()
{
    sum s2("hoytr");
    sum s("hi");
    cout<<s2+s;
return 0;
}
