scanf() is designed to stop reading in characters when it encounters a whitespace character. If you use fgets() instead of scanf() in the first example, it works just as fine.

I was trying to test the code in the above question with space delimited words as input from the SL code playground input but the tokenizing didn't work as I expected. Any ideas on what I may be doing wrong?

On the other hand, if I provide the string to be tokenised within the code itself, it works. https://code.sololearn.com/cZLyNIM4ETvY/?ref=app

It might be because of scanf. Try to get a whole line instead. (try with gets, maybe?)

Sonic indeed, I didn't see the Shadow answer... 😅 Sorry! (I think I was writing at the moment Shadow answered).
