In the Find and Replace function, which symbol can be used to represent a single character as a wildcard?

In the Find and Replace function, the question refers to the use of wildcards, which are special characters that allow for flexible search operations. The symbol that represents a single character as a wildcard is the question mark. This is essential for facilitating searches when you are unsure of a specific character in a word or phrase.

For example, if you use "c?t" in the Find and Replace field, it would match words like "cat," "cut," or "cot," as the question mark can substitute for any individual character. This feature enhances the utility of the Find and Replace function by allowing users to find variations of words without needing to spell out each possible iteration completely.

Other symbols mentioned in the options serve different purposes: the asterisk represents multiple characters or no character at all, the number sign (#) is often used in other contexts but does not function as a wildcard for a single character, and the exclamation mark does not hold any specific function related to wildcards in this context. Thus, the question mark is the correct choice for representing a single character when using wildcards in the Find and Replace functionality.
