Wraps the type of an array element.
template<int Idx, class Ty, std::size_t N>
class tuple_element<Idx, <array<Ty, N> > {
typedef Ty type;
};
Template Parameters
Idx
The element offset.Ty
The type of an element.N
The size of the array.
Remarks
This template class is a specialization of the template class tuple_element Class <tuple>. It has a nested typedef type that is a synonym for the type of the Idx element of the array.
Example
// std_tr1__array__tuple_element.cpp
// compile with: /EHsc
#include <array>
#include <iostream>
typedef std::array<int, 4> Myarray;
int main()
{
Myarray c0 = {0, 1, 2, 3};
// display contents " 0 1 2 3"
for (Myarray::const_iterator it = c0.begin();
it != c0.end(); ++it)
std::cout << " " << *it;
std::cout << std::endl;
// display first element " 0"
std::tuple_element<0, Myarray>::type val = c0.front();
std::cout << " " << val;
std::cout << std::endl;
return (0);
}
0 1 2 3 0
