Closing programs

Ironically it's actually the opposite. Linux has signals, and with the exception of SIGKILL and I think SIGABRT they can all be handled gracefully. Windows on the other hand doesn't have signals, it can only TerminateProcess() which is forceful. The illusion of graceful termination on windows is done by sending a Window close message to all of the windows belonging to a given process, however in the event the process has no windows, only forceful termination is available due to the lack of a real mechanism to gracefully terminate processes. That's why the taskkill command tells you a process requires forceful termination when you run it against something headless.

You can certainly change it. But should you?

const volatile is used a lot when doing HW programming. Const will prevent your code from editing it and volatile prevents the compiler from making assumptions. For example reading from a read only MMIO region. Hardware might change the value hence volatile but you can't because it's read only so marking it as const allows the compiler to catch it instead of allowing you to try and fail.
