Answer 1

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.

Answer 2

Martin Taylor thanks. I didn't know about %*c

Answer 3

Théophile thanks. Shadow indicated that too.

Answer 4

Coder Kitten I didn't know that option. Thanks!

Answer 5

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?

Answer 6

Shadow brilliant! Thanks.

Answer 7

On the other hand, if I provide the string to be tokenised within the code itself, it works.

Answer 8

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