Can a C++ function return more than one value? [duplicate]

Answer 1

There are several ways to achieve that.

1. If you have objects of the same type, std::array would be a good return type for that.
   If you have varying numbers, use std::vector instead.

2. If you have (a fixed number of) different types, use std::tuple:

   std::tuple  f()
   {
     return std::tuple ( 42, 4711l, 3.141 );
   }
   

I know no way to return a varying number of non-polymorphic objects of different types built into the language or standard library.
