.What is a wildcard character? How would you use it to find a record?
7nadin3 [17]

Answer and Explanation:

A wildcard character is a character that can be substituted for either a single character or a string of characters. For instance, in certain operating systems, the asterisk character "*" can be used in lieu of a set of characters, while the character "?" can be used in lieu of a single character.

It is a special character that represents one or more other characters. The most commonly used wildcard characters are the asterisk (*), which typically represents zero or more characters in a string of characters, and the question mark (?), which typically represents any one character.

For example, in searching: run* would mean "any word that starts with 'run' and has any kind of ending." If you entered "run*" at a search engine that offered a wildcard character capability, you would get results for run, runs, running, runner, runners - in short, any possible word that might begin with the three letters.

Use of wildcard character:

Wildcard characters are utilized in customary articulations (a programming type wherein input information is adjusted depending on indicated designs) and in scanning through record catalogs for comparable document names (for instance, if all the work documents on an undertaking start with the characters "F7," you could undoubtedly find all the venture records by just looking for "F7*").  

It is a special case character and is a sort of Meta character .  

In different card games, a wildcard is an assigned card in the deck of cards.
