#include <type_traits> 
#include <iostream> 
 
typedef std::aligned_storage<sizeof (int), 
    std::alignment_of<double>::value>::type New_type; 
int main() 
    { 
    std::cout << "alignment_of<int> == " 
        << std::alignment_of<int>::value << std::endl; 
    std::cout << "aligned to double == " 
        << std::alignment_of<New_type>::value << std::endl; 
 
    return (0); 
    }
