You need some sort of event handling... Don't really know what libs are used under lin.

As I said, I don't really now those libraries, try googling something like "c++ checking if key is pressed", or adding linux in there.

yes i have searched but c++ doesnt support an event handling so i'm curious if even theres a way to stop a loop when a key is pressed without using instructions like cin as they have to wait for an input.thank you anyway

there must be a library.
And what I mean is, you run a loop (at limited FPS, not to kill the CPU) and in every loop you check if the key was pressed.
Good tutorial on that is at LazyFoo, but it uses a graphic library (SDL) which IMO would be an overkill here, but why not?

In Standard C++ there is not. ESC is not a magic key today*. Just use ENTER.
* It never really was. The use of ESC has always been non-portable and much more difficult to program.
