modifying a loop with input

[iochinome]

hey guys, so i am doing a project in which i need to be able to get input to alter the processes of a loop while it is running, but without disrupting the loop- so, if the user enters a character and hits enter, for instance, the value of some variable in the loop would be changed, but otherwise the loop continues on unstopped. is there a way to do this? thanks!

You will need to perform the loop in a worker thread and regularly (e.g. each iteration) check some shared resource, such as a bool variable.
In your main thread you then set the bool variable when you want the for-loop to stop.

Try kbhit if you are using windows platform. Unfortunately C++ istream classes do not support asynchronous input. So, there is no standard way of doing it.

Actually, you could use a second thread. Do all your work (the loop) in the thread, and have your main thread waiting on input.
