explain wild card characters
Answers
Wildcard. Alternatively referred to as a wild character or wildcard character, a wildcard is a symbol used to replace or represent one or more characters. Wildcards are typically either an asterisk (*), which represents one or more characters or question mark (?), which represents a single character.
" ? " and " * " are wild card characters and they are used when we do not the exact name of any file on our computer. Suppose, the name of your file is " Brainly " and you do not know the entire name of file. Then you may write " ? " in the place of the letter which you do not know, say " Brainl? ". Similarly we can also use " * " but it is used in place of more than one letter, like, " Brai* ".
Therefore, since the use of such characters are already set, they cannot be used in the file name.
