Checking whether the memory allocated is aligned

In the previous recipe, you have learned how to use C++11 to allocate aligned memory. The question now is: how do we know that memory is properly aligned? This recipe will teach you about this.

How to do it...

We'll be using the previous program, and by modifying it a little, we'll see how to check whether a pointer is aligned or not:

1. Let's modify the previous program, as follows:

#include <type_traits>
#include <iostream>

using intAligned8 = std::aligned_storage<sizeof(int), 8>::type;
using intAligned4 = std::aligned_storage<sizeof(int), 4>::type;

int main()
{
    intAligned8 i; new(&i) int();
    intAligned4 j; new (&j) int()...
