// std__array__array_back.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 last element " 3"
std::cout << " " << c0.back();
std::cout << std::endl;
return (0);
}
