C++ Terminal Closes on Enter

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

Forgive me for my rather extreme newbie-ness in the field of C++ but here goes. :)

When I run say for example this code in a terminal:

int g;
cout << "Please enter an integer value: ";
cin >> g;
cout << "The value you entered is " << g;

...to you C++ experts out there, obviously this accepts a value from the user's input and then displays in the output. However, right after I "submit" my input and click enter, I see the output for a mere millisecond and then the terminal closes. Anyway I could stop the terminal from closing so I could actually have a chance to see the result?

I'm using Visual Studio on Windows 7.

Thanks!

Add `cin.get()` after the `cout`. Then hit return to continue when you are ready. — hmjd, Dec 13 '12 at 14:43
Yeah, IDEs still suck after all these years. Sigh. If you happen to be on Visual Studio, use Ctrl+F5 instead of F5 to run your program. — R. Martinho Fernandes, Dec 13 '12 at 14:43
If you are not using the debugger you can do what I have done for the last 20+ years. Open a console window and run your application from that. — drescherjm, Dec 13 '12 at 14:55

If you're working on Windows, you can add the line system("pause"); at the end of the program. Or cin.get() if on Linux

system("pause'); works great. Just seems a little weird that Visual Studio does this with their terminal – codedude Dec 13 '12 at 14:59
Prefer `cin.ignore(10000, '\n');` to `cin.get()`. It works on both platforms. – Thomas Matthews Dec 13 '12 at 16:46

Depends on what you're using. For Windows it is common to use a breakpoint (__debugbreak) but for Unix people usually just run it in an existing terminal which does not close.

I don't know what kind of OS do you use, but the function is similary

start a terminal in Linux oder a Commandline in Windows. Switch with the command "cd" to the directory where the Program lies.

Linux:

./myProgram

Windows

myProgram

The Terminal which you started wouldn't be closed ;)
