// The arraysize(arr) macro returns the # of elements in an array arr.

// a pointer by mistake, you will get a compile-time error.

|

// One caveat is that, for C++03, arraysize() doesn't accept any array of
|
|
// an anonymous type or a type defined inside a function. In these rare
|
|
// cases, you have to use the unsafe ARRAYSIZE() macro below. This is
