Edit Question
Title
Body
I am reading a book on regular expression and I came across this example for \b : The cat scattered his food all over the room. Using regex - \bcat\b will match the word cat but not the cat in scattered . For \B the author uses the following example: Please enter the nine-digit id as it appears on your color - coded pass-key. Using regex \B-\B matches - between the word color - coded . Using \b-\b on the other hand matches the - in nine-digit and pass-key . How come in the first example we use \b to separate cat and in the second use \B to separate - ? Using \b in the second example does the opposite of what it did earlier. Please explain the difference to me. EDIT: Also, can anyone please explain with a new example?
