What is a word boundary example?

A word boundary, in most regex dialects, is a position between \w and \W (non-word char), or at the beginning or end of a string if it begins or ends (respectively) with a word character ( [0-9A-Za-z_] ). So, in the string “-12” , it would match before the 1 or after the 2. The dash is not a word character.

What is \b word boundary?

\b is a zero-width word boundary. Specifically: Matches at the position between a word character (anything matched by \w) and a non-word character (anything matched by [^\w] or \W) as well as at the start and/or end of the string if the first and/or last characters in the string are word characters.

What is a non-word boundary?

A non-word boundary matches any place else: between any pair of characters, both of which are word characters or both of which are not word characters. at the beginning of a string if the first character is a non-word character. at the end of a string if the last character is a non-word character.

What is NSRegularExpression?

The NSRegularExpression class lets you find and replace substrings using regular expressions, which are concise and flexible descriptions of text. caseInsensitive) let matches = regex. matches(in: input, options: [], range: NSRange(location: 0, length: input. utf16. count)) if let match = matches.

What is a word boundaries in linguistics?

What is word boundary in C language?

How do I know if my address is aligned?

In any case, you simply mentally calculate addr%word_size or addr&(word_size – 1) , and see if it is zero. When the address is hexadecimal, it is trivial: just look at the rightmost digit, and see if it is divisible by word size. For a word size of 4 bytes, second and third addresses of your examples are unaligned.
