from The Free On-line Dictionary of Computing (8 July 2008)

question mark
?
ques

   <character> "?", {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 {Unix} {shell} file name patterns, question mark matches
   any single character.
