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.

It is a part of a C string. However it is not counted by strlen.

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 format for size_t is %zu. If your compiler does not support this
then the next best method is to use %lu and cast it's argument to
unsigned long.

Printing the value of hello instead of t has a bigger effect than
using the wrong format spec.

Oops. Yes, another case of reading what I expected to read I suppose. In
which case the output that the OP mentioned is wrong. I think this
proves finally that the OP *is* a troll.
