Question about the volatile keyword http://stackoverflow.com/questions/3263873/question-about-the-volatile-keyword this question It's used in low level programming with interrupts and so on mostly volatile int count void test while count 100.. unless you change it. Unless you are using low level interrupts or some uses of threading then you don't need to use it. EDIT.. could be misleading. The examples and stuff about hardware interrupts etc in my post are what volatile is for it absolutely ISN'T..
