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);
