C++17: Structural Binding – Tuple Object

Below is an example of structurally binding a tuple object:

#include <iostream>
#include <tuple>

int main()
{
  std::tuple<int, double, int, double> myTuple{1, 2.2, 3, 4.4};

  auto [a, b, c, d] = myTuple;
  std::cout << a << " "; // 1
  std::cout << b << " "; // 2.0
  std::cout << c << " "; // 3
  std::cout << d << " "; // 4.0
  std::cout << std::endl;
  return 0;
}
// Output: 1 2.2 3 4.4
