How to close an infinite loop in c++

Question

C++

Answer 1

It depends on where the program is running. In SoloLearn playground, the server exits the program after it hits a time limit so you don't need to worry about it. Some systems give you a character you type to abort the program. I've built systems where my task manager detected a task that failed to return to its top level loop.

Answer 2

Windows:
Ctrl-Break : instantly sends an IRQ (Interrupt ReQuest)
Ctrl-C : but requires the keyboard to be read in some way

Linux, Apple, Android:
Ctrl-Break (if available; try Fn+Esc for OSX)
Ctrl-C (SIGTERM -inate)
Ctrl-Z (SIGHUP : hangup)
Ctrl-\ (SIGQUIT)

Notes:
On PC's the "break" key is usually combined with the "pause" key, at the upper right corner.
SIGHUP only "backgrounds" the foreground process (it's still there) but you usually get a shell so you can use "ps" to find your process and "kill" it with a signal.
You may need to press Enter to update the display after some of these key combos.

Should you see this advice elsewhere:
Kill-by-task-manager (in general, not special stuff like John Wells'), kill -9 (SIGKILL) and SIGSTOP should only be used as a last resort for a hung process; they're dirty kills.

Answer 3

no I asked how to come out of the program once an infinite loop begins…
