/*
The above code is portable when used with char type
However, according to C standards section 6.2.5-26,
this code is not portable when used with other types.
Even though this code is not portable with other types,
the code will still work on most implementations.
If portability is needed, then specialize the above
code to the desired type.  That will make it portable.
