I ran this code(which runs perfectly):

C++

#include <iostream>
using namespace std;
  
struct myint
{
private:
    int night;
public:
    myint() {}
    myint(int good) : night(good) {}
    
    myint operator+ (myint& input)
    {
        cout << night + input.night * 2;
        return 0;
    }
    
};
int main()
{
    myint hello(2);
    myint good(3);
    myint result = hello + good;
    return 0;
}

However, the problem i have is in the line where it says cout << night + input.night * 2. I dont know why i need to add the input.night and not just input. I want to know what the significance of the .night at the end is.

If you add night (i.e. this->) with input then ther is a type mismatch, because the former is a int while the latter is a myint.

That said, I would rewrite it this way

C++

#include <iostream>
using namespace std;

struct myint
{
private:
    int night;
public:
    myint(int good) : night(good) {}

    myint operator+ (const myint& input)
    {
      myint result(night + input.night * 2);
      return result;
    }
    int get() { return night;}
};

int main()
{
    myint hello(2);
    myint good(3);
    myint result = hello + good;
    cout << result.get() << endl;
}
