Thread: The switch statement when comparing a character

We have code like this in an old parser we wrote:

Code:

char *word;

...
...
switch (*word)
{
   case 'A': ...; break;
   case 'B'; ...; break;
   case '-'; ...; break;
   ...
}

Now if we use the generic data type TCHAR, do we code it like this?

Code:

TCHAR *word;

...
...
switch (*word)
{
   case _T('A'): ...; break;
   case _T('B'); ...; break;
   case _T('-'); ...; break;
   ...
}

or does the switch statement assumes a single byte character?

Thanks,

But I was not comparing integers, I was comparing characters. So what you are saying underneath it really compares the ASCII value of the characters?

If so than the "wide" version will not work correct?

Depends what a TCHAR is. If TCHAR isn't an alias for some integral type, then no. TCHAR is not a standard C type.

TCHAR is a macro which means char when UNICODE is defined and means wchar_t when UNICODE is not defined.

So in summary, my question is really if TCHAR is wchar_t would this work?
