Question

#include <cmath>
#include <iostream>
#include <cstdlib>
using namespace std;

class myClass {
    int d;

public:

    myClass(){};

    int get_rand() const {
        return rand() % 10;
    }
};

int operator +(myClass d, myClass e) {
    return d.get_rand() + e.get_rand();
}

int main() {
    myClass mC;
    int sum = mC + mC;
    cout << sum;

}

I want to be able to had as many Mc’s as I want eg. int sum = mC + mC + mC + mC;

Answer 1

You need an overloaded operator for this, namely int operator+(int, myClass):

int operator +(int d, myClass e) {
    return d + e.get_rand();
}

+ operations are evaluated left-to-right, so the type of mC + mC is int. This is why you need another operator int operator +(int, myClass).
