On the same note: have a look at the strlen() function they have (at
the
risk of generating even more revenue for the owner of this page,
but we have done him a lot of good already, so...)
/* code on their site */
int strlen(char *string)
{
char *p=string;

while(*p!='\0')
p++;

return(p-s);
}
and check with (as it is somewhat closer to, the signature part)
/* code from K&R, a not-so-old version */
int strlen(char *s)
{
int n;

for (n = 0; *s != '\0', s++)
n++;
return n;
}
as well as the signature of what we have on most systems ...
size_t strlen(const char *s).

This might just tempt you all the more to stay away!

Suman.

P.S: Don't flame me for pulling down K&R, to their standard & win the
argument by sheer experience.
