-if / else
-=========

-**if/else** allows greater control over the flow of code than the
-basic **if** statement, by allowing multiple tests to be grouped
-together. 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

+``if``/\ ``else`` allows greater control over the flow of code than
+the basic :ref:`if <arduino-if>` statement, by allowing multiple tests
+to be grouped together. For example, an :ref:`analog input
+<arduino-analogread>` could be tested, with 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)
-    {
+    if (pinFiveInput < 500) {
       // action A
-    }
-    else
-    {
+    } else {
       // action B
     }

-**else** can proceed another **if** test, so that multiple,
-mutually exclusive tests can be run at the same time.

+``else`` can precede 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.
