Can we return two values from a single function?

Question

Can we return two different values from a single function?
Is that even possible...

Answer 1

You can use std::pair, it can carry two different types which you can define in function template. Here's an example for you : )

#include <iostream>
#include <utility> // std::pair

// References:

// http://www.cplusplus.com/reference/utility/pair/

template <class A, class B>
std::pair<A, B> my_function(A a, B b)
{
std::pair<A, B> rv {a, b};
return rv;
}

int main()
{
std::pair<int, double> sample {my_function(2018, 20.18)};
std::cout << "First (int): "
<< sample.first;
std::cout << "\nSecond (double): "
<< sample.second;
return 0;
}

Well, now both threads has answers, but it means you had made duplicates.

Answer 3

Yes, you can return them in a tuple and acces the first value like this:

print(function()[0])

And the second value like this:

print(function()[1])

The return statement should look like this:

return (value1, value2)

You can have more values in the array and it would still work

Answer 4

Wait i just realised that you were asking about c++ so the code doesn't work but the theory still applies
