For example, an analog input could be tested and one -action taken if the input was less than 500, and another action -taken if the input was 500 or greater. The code would look like -this: - - - -:: - - if (pinFiveInput < 500) - { - // action A - } - else - { - // action B - } - - - -**else** can proceed another **if** test, so that multiple, -mutually exclusive tests can be run at the same time. - - - -Each test will proceed to the next one until a true test is -encountered. When a true test is found, its associated block of -code is run, and the program then skips to the line following the -entire if/else construction. If no test proves to be true, the -default **else** block is executed, if one is present, and sets the -default behavior. - - - -Note that an **else if** block may be used with or without a -terminating **else** block and vice versa. An unlimited number of -such **else if** branches is allowed. - - - -:: - - if (pinFiveInput < 500) - { - // do Thing A - } - else if (pinFiveInput >= 1000) - { - // do Thing B - } - else - { - // do Thing C - } - -Another way to express branching, mutually exclusive tests, is with -the `switch case <http://arduino.cc/en/Reference/SwitchCase>`_ -statement. - - - -See also: ---------- - -`switch case <http://arduino.cc/en/Reference/SwitchCase>`_ - |
