Returning multiple values from a C++ function

In C++11 you can:

#include <tuple>

std::tuple<int, int> divide(int dividend, int divisor) {
    return  std::make_tuple(dividend / divisor, dividend % divisor);
}

#include <iostream>

int main() {
    using namespace std;

    int quotient, remainder;

    tie(quotient, remainder) = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

In C++17:

#include <tuple>

std::tuple<int, int> divide(int dividend, int divisor) {
    return  {dividend / divisor, dividend % divisor};
}

#include <iostream>

int main() {
    using namespace std;

    auto [quotient, remainder] = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}

or with structs:

auto divide(int dividend, int divisor) {
    struct result {int quotient; int remainder;};
    return result {dividend / divisor, dividend % divisor};
}

#include <iostream>

int main() {
    using namespace std;

    auto result = divide(14, 3);

    cout << result.quotient << ',' << result.remainder << endl;

    // or

    auto [quotient, remainder] = divide(14, 3);

    cout << quotient << ',' << remainder << endl;
}
