I strongly recommend using either of the constructs:

static char xyz[] = "string";
/* at some point later in your code */
... sizeof xyz ... /* no overhead in using the symbol: xyz */

OR

... sizeof (char *) ...

Depending on what result you are looking for.

Note: (sizeof xyz) == (strlen(xyz) + 1) in THIS case. After all, I could
set xyz[0] = '\0', and the equality will not hold.
Remember: sizeof does not generate any run time code (unlike the strlen);
it is evaluated at compile time.
