Answer 1

If you want extra chatacter (in C), use extra %s.
Or use _ instead of space between words.
If you use 'hello world', it will become :
%s = 'hello'
'world' is ignore because it is not decimal.
%d = 0 because that's i default value.

here modified version if you want to use space.

PS. i m not a c programmer, that's just how i think about that.
Sry if i m wrong.

Answer 2

Bro "i" default value is garbage value here since it is auto variable
