Parameters

t	Tuple to index

A reference to the selected element of t.

Example:

 
#include <kumi/tuple.hpp>
#include <iostream>
 
int main()
{
  using namespace kumi::literals;
 
  kumi::tuple t = { 1, 2.3, 4.5f, '@' };
 
  std::cout << kumi::get<0>(t) << "\n";
  std::cout << kumi::get<1>(t) << "\n";
  std::cout << kumi::get<2>(t) << "\n";
 
  kumi::get<3>(t)++;
 
  std::cout << kumi::get<3>(t) << "\n";
}
