Answer 1

Because the '\n' character is a new line, not a literal \n. Try entering this:

hello
world
#
// not "hello world#"

Answer 2

First, you are counting in W_num the number of characters, not the number of words.
Second, your code is correct, just be sure to input a newline instead of \n (byte value 0xA).

You can test it adding a printf("%x ", num); as first instruction of your while loop.
If you for example input

and click SUBMIT, the output will be, as expected
