0 Rules for constructing character constants

A character constant is a single alphabet, a single digit or a single special symbol enclosed in apostrophes( i.e. single quotation marks). Both the inverted commas should point to the left. For example, ’A’ is a valid character constant whereas ‘A’ is not.

  Character constants have integer values that are determined by the computer' particular character set. Thus the value of character  constant may vary from one computer to another.

The maximum length of a character constant can be 1 character.

Example-

              'a'

               'I'

              '56'

              '='
