    be sure to include conio.h and before the 'return 0;' put getch();

    Code:
    #include <iostream.h>
    #include <conio.h>
    
    int main()
    {
        //all your hello world stuff
        _getch();
        return 0;
    }
    the _getch(); will wait for a keypress to continue.

    unregistered.. you problem is your DOS Settings not your hello world app.

    do this

    go to start/ click run / type in "COMMAND"/ go to the directory containing your hello world app and then run it.. you should be all good

    ss3x... adding a getch() is more mobile and compatible.

    restricting it to only work run from a dos window is pointless, when it only takes an extra line or 2 to make it mobile. ok?

    Hello? conio is not standard so anything from it is not portable.

    Do this:
    Code:
    #include <iostream>
       using std::cout;
       using std::cin;
    
    int main()
    {
       cout << "Hello world\n";
    
       cin.get();   // Pauses until enter is pressed
    
       return 0;
    }

    biosx : i mean executable-wise it is portable.

    what good is it if you have to spend 5 seconds getting to dos every time when you could spend 5 seconds once writing getch(); ??? plus if it was distribute, way more mobile

    Just putting a getch() does not change anything. It is still a console application (notice I didn't say DOS application, b/c there is a difference between DOS programming and console programming).

    however way you code it:

    Code:
    #include <iostream>
       using std::cout;
       using std::cin;
    
    int main()
    {
       cout << "Hello world\n";
       
       cin.get();   // Pauses until enter is pressed
    
       return 0;
    }
    == and this ==

    Code:
    #include <iostream>
       using std::cout;
    
    #include <conio.h>
    
    int main()
    {
       cout << "Hello world\n";
       
       getch();   // Pauses until key is pressed
    
       return 0;
    }
    ... will still run in console windows without having to open up a cmd-term.

    Oh jeez.... just use conio for now; it's easier. It really doesn't matter which way you use. Go buy a C++ book not published by sams and not a _____ for dummies book.
