<p class='vspace'></p><h2>switch / case statements</h2>
<p>Like <strong>if</strong> statements, <strong>switch...case</strong> controls the flow of programs by allowing programmers to specify different code that should be executed in various conditions. In particular, a switch statement compares the value of a variable to the values specified in case statements. When a case statement is found whose value matches that of the variable, the code in that case statement is run.
</p>
<p class='vspace'></p><p>The <strong>break</strong> keyword exits the switch statement, and is typically used at the end of each case. Without a break statement, the switch statement will continue executing the following expressions ("falling-through") until a break, or the end of the switch statement is reached.
</p>
<p class='vspace'></p><h3>Example</h3>
<pre>
switch (var) {
case 1:
//do something when var equals 1
break;
case 2:
//do something when var equals 2
break;
default:
// if nothing else matches, do the default
// default is optional
}
</pre>
<p class='vspace'></p><h3>Syntax</h3>
<pre>
switch (var) {
case label:
// statements
break;
case label:
// statements
break;
default:
// statements
}
</pre>
<p class='vspace'></p><h3>Parameters</h3>
<p>var: the variable whose value to compare to the various cases
</p>
<p class='vspace'></p><p>label: a value to compare the variable to
