    lol.......that was good people. It looked weird, but I thought Prelude was being serious. Good stuff people. Luckily you gave us the right answer let on, I could see myself arguing already...

    someonelse-"You're wrong.......Why do you say that"
    Me-"Because Prelude said it that's why!"

    Trust me, those tutorials are EXTREMELY out dated. I understand how you don't wanna spend money (yet) on programming, but here's a good suggestion: go to the library and get a book on C++. Don't get books that were printed back in the 19xx , cuz they are as old as da tutorials on this site. Then, if you know you're interested, start buying books. Good C++ books out there should give many examples on usage of the language and should be understandable even by dummies.Try <Ivor Horton's Beginning C++> if you like, cuz that's the one I read. One more thing, instead of using cin.get() , you can also use system("PAUSE") . It prompts the user to press any key before closing.

    Code:
    #include <iostream>
    using namespace std;
    
    int main()
    {
        cout << "Hello world." << endl;
        system("PAUSE");
        return 0;
    }

    There are operating systems that do not have the PAUSE command, so I'd recommend not using system("PAUSE"); because of it's lack of portability. And cin.get()
    1) does basically the same thing
    2) doesn't rely on an expensive system call
    3) is already part of the compiler
    4) is fully portable to any C++ compiler

    why is this better than
    Code:
    cout << "Hello World!";
    cin.get();

    >why is this better than
    If you don't make the names cin and cout visible, it's better because your way wouldn't compile. Otherwise it's a matter of style.
    My best code is written with the delete key.

    Some folks believe that you shouldn't "bring in" an entire namespace into the global namespace with "using namespace std;"

    I have not problems with bringing in the entire "std" namespace into an application - if you do end up with namespace collisions, the compiler will let you know.
