Why does struct alignment depend on whether a field type is primitive or user-defined?

Now if we combine all that and create struct:
struct RefAndTwoInt32Wrappers
{
public int x,y;
public Int32Wrapper z;

What does the Java assert keyword do, and when should it be used?

fill: red;
}
Or:
.social-link:hover p...
How to create a trie in Python
... I'd stick with dict.setdefault() (it's underutilised and not nearly well-known enough), in part because it helps prevent bugs that are too easy to create with a defaultdict (where you'd not get a KeyError for non-existing keys on indexing).
