    Exclamation Console Window Dissapears after hitting Enter

    I made a very simple program here:

    Code:
    #include <iostream>
    #include <string>
    using namespace std;
    
    // Prompt the user to enter a name, collect the name,
    // and display a message to the user that contains
    // the name.
    int main()
    {
        string userName;
    
        cout << "What is your name? :";
        cin >> userName;
        cout << "Hello " << userName << "!" << endl;
        cin.get();
        return 0;
    }

    After I put my name in, I push enter, then the window dissapears. Why? Thanks in advance.

    See the Programming FAQ.

    This is a "feature" of Windows. It closes the window when the program is done.

    When you entered the input, the '\n' was left in the stream. Hence, cin.get() extracted the '\n' and the program ended. Add cin.ignore() or another cin.get() before cin.get().

    Thank you JaWib. I took your advice and put another cin.get(); before my other one and it WORKED.

    One line before "return 0;" you should write:

    System("pause");

    The Console will wait to a second hit of the return key.

    you can also replace cin.get() with getch(). it'll keep the console window open until you press a key. but'd you'd have to include conio.h to use it.
