Save me a trip to the library and tell me when strlen() would not return the
length of a string?
I've been a C programmer for over a decade now and can't think of a reason why
this would be considered a bad thing. At the very heart of strlen would be a
loop something along the line of
int count = 0;
while (*(string++))
count++;
Yes my C's getting rusty but can you think of a better/faster way to count the
characters in a zero-terminated string?
-A.
