Nice video again. I like when you give use cases for the functions. Only thing maybe I would have added for these videos using functions is the reference to the man pages. I know these can be cryptic for beginners but it is important to learn how to read them if one wants to use C professionally. For instance in this case looking into man I saw there is not only strcspn but also strspn and then I could play with both and expand a bit your example. This active approach can be very helpful for learning. What I have been trying to do is before watching your videos check the man for the function and try to come up with a simple example by myself. Then I watch the video and expand my understanding by adding your perspective.

Wow amazing - I can use it in hundreds of different applications! When SQL, Excel and C meet together miracles happen LOL - Thanks Kevin.

s + 1 is pointer arithmetic basically
