files are not sorting in C - arrays

My program is supposed to print the current directory in the tree format. It goes through the sorting perfectly fine, except for the final folder it's checking. For some reason, the hw2 works fine, but hw1 does not sort.
now, print the words in the order.
.
- hw2
- find.c
- ls.c
- Makefile
- tree.c
- hw1
- grep.c
- factor.c
- uniq.c
- monster.c
- sort.c
- tree.c
- tree
I feel like I'm missing something, but I can't find out how to make it work. I've tried different methods and non have worked. Is there anything I can do?
