I know that this does not relate to the original question, but there's an
off-by-one error in your code. The first letter of the original string
will
not be displayed, i.e. "Hello" turns to "olle" rather than "olleH". You
probably meant this:

void Reverse( const char* CString, int length )
{
     while ( length-- )
     {
        std::cout << CString[length - 1];
     }
}
