If you typed in 'hi' then arr will contain:
[h][i][0]

i think you meant: [h][i][\0]

followed by MAXLENGTH-3 garbage characters.

what does that mean ?

[garbage][h][i][\0] OR [h][i][\0][garbage]


The latter.


Also, you are supposed to reverse the string in place.

i am doing it but it is not working

Actually, you're not. In-place means only using additional storage of
constant size; you are using additional storage of size O(n).


Hint:
call strlen() to find out how big it is.

can't, K&R2 have not discussed "strlen()" yet.

Then you need to find it in some other way. Hint: the string ends with
'\0'...
