The best way to get help here is to post a _few_ lines of something that you
can not get to work. If you explain what you are trying to do, someone may
help you over the hard spots. Many here don't respond if they feel that to
answer might be the same as doing your homework for you.

That said, if you are using an array to address your word (if that's what
you have) then the character at position i (zero relative) is addressed as
array_name[i]. If you are using a pointer, character #i may be adressed as
*(ptr + i).
