Is s [I]='\ 0', suppose I input the integer - 12, then s [0] is' 2 ', s [1] is' 1 ', s [2] is' - ', then the problem to the s [I] to [3], that is, '\ 0' s, I think printf output became '\ 0' - 1 instead of 2-12 '\ 0', but why tutorial so to write? Really think impassability, two days, is really annoyed
