The following text is displayed on page 135 of ["C in a Nutshell (2nd Edition)."](http://shop.oreilly.com/product/0636920033844.do)

```
#include <stddef.h>              // Definition of the type wchar_t
/* ... */
wchar_t dinner[] = L"chop suey"; // String length: 10;
                                 // array length: 11;
                                 // array size: 11 * sizeof(wchar_t)

```

In the above example, I would think `"chop suey"` is the same as `'c', 'h', 'o', 'p', ' ', 's', 'u', 'e', 'y', '\0'`. That's 10 elements in the array. 

My question is: **Why is the "array length" different from the "String length" in this example?** Where is this length of 11 coming from? Is there something special about the `wchar_t` type that is causing this?
