Re: strcat strncat and strlen

You are not making any sense. Are you asking why strlen exists? It
should be obvious, even to you. How else do you find the length of a
zero terminated string?

C must not count '\0' as being part of a string. This is the simple code
I tried,

int main(void) {
size_t t;
char hello[]="hello world\n";
t=strlen(hello);
printf("%i",hello);
}
The integer returned was 12. When I removed the '\n' from the string
and recompiled 11 was the number returned.
Why in production code would someone want to know the length of a
string? That's what I am asking. Hence my inexperience speaks for itself.
