Size of char array

Using Arduino Programming Questions
1

char request [] = "Hello\n";
Serial.println(request) gives the output 7.

How is it that the char request [] = "Hello\n" get the length 7?
Should not it instead be 6 then \ n correspond well just one character?

Shouldn't

Serial.println(request);

print Hello, not a number.

Assuming you used sizeof, then seven is correct.
strlen would have returned six.
