"?", ASCII character 63. Common names: query ITU-T: question mark ques. Rare: whatmark INTERCAL: what wildchar huh hook buttonhook hunchback. Question mark is used, along with colon for C' s lazy triadic "if" operator (similar to the IIF function in Visual BASIC). The expression x?y:z evaluates x, then if x is true it returns y else it returns z. In Unixshell file name patterns, question mark matches any single character. (2003-06-17)
