.. _lang-break:
``break``
=========
``break`` is used to exit from a :ref:`while <lang-while>`\ ,
:ref:`for <lang-for>`\ , or :ref:`do/while <lang-dowhile>` loop,
bypassing the normal loop condition. It is also used to exit from a
:ref:`switch <lang-switchcase>` statement.
Example
-------
::
for (x = 0; x < 255; x ++)
{
digitalWrite(PWMpin, x);
sens = analogRead(sensorPin);
if (sens > threshold){ // bail out on sensor detect
x = 0;
// this line of code means that we'll immediately exit
// from the "for" loop:
break;
}
delay(50);
}
