C++ std::get fails

Question

How do I use a variable to index into a tuple using std::get<>? I have the following code:

#include 
#include 
using n         


        

Answer 1

Any idea how to make that work?

Option 1

Use compile time constants to access the std::tuple.

cout << "#" << 1 << ":" << get<0>(data) << endl;
cout << "#" << 2 << ":" << get<1>(data) << endl;

Option 2

Use a container type whose elements can be accessed using an index at run time.

std::vector data{5, 10};

or

std::array data{5, 10};
