How to Stop C++ Console Application from Exiting Immediately

How to stop C++ console application from exiting immediately?

Edit: As Charles Bailey rightly points out in a comment below, this won't work if there are characters buffered in stdin, and there's really no good way to work around that. If you're running with a debugger attached, John Dibling's suggested solution is probably the cleanest solution to your problem.

That said, I'll leave this here and maybe someone else will find it useful. I've used it a lot as a quick hack of sorts when writing tests during development.

At the end of your main function, you can call std::getchar();

This will get a single character from stdin, thus giving you the "press any key to continue" sort of behavior (if you actually want a "press any key" message, you'll have to print one yourself).

You need to #include <cstdio> for getchar.

C++ console application exiting immediately? [duplicate]

Remove statement

cin.get();

and use Ctrl+F5 to run the program from the IDE.

This statement

cin.get();

reads the new line character that is present in the input buffer of the standard stream after entering a number in the input statement above. Or use a call of cin.ignore (at least as cin.ignore()) with an appropriate argument before calling cin.get() to clear the buffer.

You can just compile (start debugging) your work with Ctrl+F5.

Try it. I always do it and the console shows me my results open on it. No additional code is needed.

Preventing console window from closing on Visual Studio C/C++ Console application

Starting from Visual Studio 2017 (15.9.4) there is an option:

Tools->Options->Debugging->Automatically close the console

The corresponding fragment from the Visual Studio documentation:

Automatically close the console when debugging stops:

Tells Visual Studio to close the console at the end of a debugging session.

Keeping the basic structure, just add Console.ReadLine() at the end

   resp3 = Console.ReadLine();
   if (resp3 == "tell me the curent date and time")
   {
      Console.Write(string.Format("{0:HH:mm:ss tt}", DateTime.Now));
   }
   Console.ReadLine();

This makes sure that the program pause at the end whether or not the correct input was entered.

How to stop console from closing on exit? [duplicate]

You can simply press Ctrl+F5 instead of F5 to run the built code. Then it will prompt you to press any key to continue. Or you can use this line -> system("pause"); at the end of the code to make it wait until you press any key.

However, if you use the above line, system("pause"); and press Ctrl+F5 to run, it will prompt you twice!

Why is the console window closing immediately once displayed my output?

the issue here is that their Hello World Program is showing up then it would immediately close.

why is that?

Because it's finished. When console applications have completed executing and return from their main method, the associated console window automatically closes. This is expected behavior.

If you want to keep it open for debugging purposes, you'll need to instruct the computer to wait for a key press before ending the app and closing the window.

The Console.ReadLine method is one way of doing that. Adding this line to the end of your code (just before the return statement) will cause the application to wait for you to press a key before exiting.

Alternatively, you could start the application without the debugger attached by pressing Ctrl+F5 from within the Visual Studio environment, but this has the obvious disadvantage of preventing you from using the debugging features, which you probably want at your disposal when writing an application.

The best compromise is probably to call the Console.ReadLine method only when debugging the application by wrapping it in a preprocessor directive. Something like:

#if DEBUG
    Console.WriteLine("Press enter to close...");
    Console.ReadLine();
#endif

You might also want the window to stay open if an uncaught exception was thrown. To do that you can put the Console.ReadLine(); in a finally block:

#if DEBUG
    try
    {
        //...
    }
    finally
    {
        Console.WriteLine("Press enter to close...");
        Console.ReadLine();
    }
#endif
