Which measure counts the number of characters in a string?

• A. Substring
• B. Arithmetic operators
• C. Length
• D. Lower

Answer: (C)

The measure that counts how many characters are in a string is its length. Length tells you the total number of characters, including letters, digits, spaces, and punctuation, and it returns that count as a number. Substring returns a portion of the string, so it doesn’t give you a count. Arithmetic operators perform calculations, not character counting. Lower changes the case of characters, not how many there are. In code you’ll often see this concept named length (or size or len), and you access it as something like string.length or LEN(string) depending on the language.
