Looking for null terminator

When working with a character array:

Code:

---

char name[256] = "";

---

I normally check to see if it is a null string by:

Code:

---

if (name[0] == '\0') ...

---

or I match along the string looking for '\0' when I parse strings some times.

at times I might even do this:

Code:

---

switch (name[i])
{
case 'A':
...
...
case 'B':
...
...
}

---

Question is, if now I declare name[256] as:

Code:

---

Tchar name[256]=L"";

---

how should my code be changed accordingly, if I will be creating the app for use in both char and wchar_t cases?

Thanks,

MC

It will be the same for both char and widechars. What matters is the define UNICODE.

The only things you should worry about is the size of your variable getting bigger. Wrapping all your string in _TEXT(). using %S identifeir for wide chars and %s for chars(UNICODE not defined).


fine on both char and widechar

Code:

---

if (name[0] == '\0')

---

Code:

---

switch (name[i])
{
case 'A':
...
...
case 'B':
...
...
}

Thanks, just to make sure I don't need to do:

Code:

---

switch (name[i])
{
case L'A':
...
...
case L'B':
...
...
}

---

Correct?

Just play it safe and do

Code:

---

switch (name[i])
{
case _T('A'):
...
...
case _T('B'):
...
...
}
