Character literals are written in single -quotes, like this: ``'A'`` (for multiple characters - strings - use -double quotes: ``"ABC"``). - - -Just like everything else on a computer, characters are stored as -numbers. You can see the specific encoding in the `ASCII chart -<http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters>`_\ -. This means that it is possible to do arithmetic on characters, in -which the ASCII value of the character is used (e.g. ``'A' + 1`` has the -decimal value 66, since the ASCII value of the capital letter A in -decimal is 65). See the :ref:`Serial.println() -<arduino-serial-println>` documentation for more information about how -characters are converted into numbers. - -The ``char`` datatype is a signed type, meaning that it encodes -numbers from -128 to 127. For an unsigned type, which stores values -from 0 to 255, just use the type ``unsigned char`` (two words). - - -Example -------- - -:: - - // the following two lines are equivalent: - char c = 'A'; - char c = 65; - - -See also --------- - - -- :ref:`arduino-int` -- :ref:`arduino-array` (a string is just an array of ``char``\ s) -- :ref:`Serial.println() <arduino-serial-println>` - - - -.. include:: cc-attribution.txt
