Ways of Pausing

======================================

#include <conio.h>

cout << "Press <Enter> to exit";

_getch();

cin.get(); // seems to be better with VS 2019 and forward so far!

======================================

system("pause");

======================================

/* Pausing when starting with Debugging (F5)

Tools, Options, Debugging, General, (scroll to bottom of General Window), check or uncheck as desired "Automatically close the console when debugging stops"

======================================

/* Pausing when starting without Debugging (Ctrl-F5)

Open your project and navigate to the following menu: Project -> YourProjectName Properties -> Configuration Properties -> Linker -> System. There in the field SubSystem use the drop-down to select Console (/SUBSYSTEM:CONSOLE) and apply the change.
"Start without debugging" should do the right thing now.

======================================
