Lock, shut down, force quit and reset in IPhone

To turn your phone completely off, press the Sleep/Wake button for a few seconds then drag the red slider that appears.

You can force quit it by pressing the Home button for at least six seconds.

You can force a reset of your phone by pressing both the Sleep/Wake and Home buttons for at least ten seconds. Note that while Apple technically calls this a "reset", it’s actually more like a "reboot" and none of your settings will be changed.
