I guess the question says it all, but, what happens if someone closes a c++ console app? As in, clicks the "x" in the top corner. Does it instantly close? Does it throw some sort of exception? Is it undefined behavior?

You can use Environment. Exit(0) and Application. Exit .
Exit(0); Or to close the current instance of the form: this. Close();
A console application, in the context of C#, is an application that takes input and displays output at a command line console with access to three basic data streams: standard input, standard output and standard error.
Closing a c++ console app with the "x" in the top corner throws an CTRL_CLOSE_EVENT which you could catch and process if you set a control handler using the SetConsoleCtrlHandler function. In there you could override the close functionality and perform whatever you wished to do, and then optionally still perform the default behavior.

I imagine that the console process just gets unceremoniously killed by the OS. If you want to trap this event and do something it looks like the SetConsoleCtrlHandler function is the way to do it.
