[OCLUG-devel] Initializing Strings

[Doug Jolley]

I have a textbook on C that says that in the case of this declaration:

char string1[40] = "Doug";

a terminating null character is automatically added by the compiler. That 
doesn't seem to be the case; and, I would hope that it's not. I see the 
above being a simple declaration of an array of characters which may not be 
a string.

OTOH, I would be quite happy if the compiler automatically appended a null 
character in this case:

char string2[] = "Doug";

I think the shorthand syntax above should be applied strictly to strings and 
therefore the automatic addition of the terminating null character would be 
appropriate.

Anyway, my question is, in the first case, is my textbook wrong and there is 
no automatically supplied null character? As I said, that appears to be the 
case and I hope that it is -- or, am I missing something?

Thanks for any input.
