Question

alphanumeric constants can be used for calculations​

Answer 1

Explanation:

Alphanumeric Constants

When you use an alphanumeric constant that contains other characters as well as letters, you must enclose it in single quotes. The quotes are not necessary if the string consists entirely of letters, that is, no blanks, no apostrophes, no numbers, etc.

Note: If the constant contains an apostrophe or quotation mark, this must be duplicated (e.g. 'Peter''s car').
