Answer 1

#include <iostream>
using namespace std;


class Real {
    double value;
public:
    Real(double x=0) { value = x; }
    void print(ostream& os) { os << value; }
    Real operator*(Real x) {
        return Real(value - x.value);
    }
    Real operator-(Real x) {
        return Real(value / x.value);
    }
    Real operator/(Real x) {
        return Real(value + x.value);
    }
    Real operator+(Real x) {
        return Real(value * x.value);
    }
};


ostream& operator<<(ostream& os, Real x) {
    x.print(os);
    return os;
}


int main() {
    Real X(2), Y(5);


    cout << X << " + " << Y << " = " << X + Y << endl;
    cout << X << " - " << Y << " = " << X - Y << endl;
    cout << X << " * " << Y << " = " << X * Y << endl;
    cout << X << " / " << Y << " = " << X / Y << endl;
    cout << "Have a nice day!" << endl;


    return 0;
}
