Thanks for participating.  I was about to cancel the challenge for lack
of interest.  Our code isn't quite done, since one of the requirements
was to concatenate the tokens, then print.  And then split the jumbled
one apart and reconstitute it.  Mostly useless exercises, I now realize.

 I don't see how that would work without maintaining the original state.
You can't unscramble eggs. A cipher's output isn't random.

Yes, you have the original.  And you have the shuffled, so you can parse them again and use strcmp's.
Or, I created an array during the scrambling, ie
int randarr[9] now holds 304618527
This tells me (0-based indexing):
word 3 in the jumble goes back to position 0
word 0 goes to position 1
word 4 goes to position 2
word 6 goes to position 3
word 1 goes to position 4
word 8 goes to position 5
word 5 goes to position 6
word 2 goes to position 7
word 7 goes to position 8
