I am extremly new to C++ (I started about an hour ago). I learned how to make the "hello world" file, but I want to know how to keep it open (because it closes automatically).

So far, I have:

#include <iostream.h>

int main()
{
cout << "Hello world!" << endl;
return(0);
}

Can someone please tell me the code to keep the window open?

Thanks

A) use code tags like illustrated in B.

B)

Code:

#include <iostream.h>
#include <stdlib.h>

int main()
{
cout << "Hello world!" << endl;
system("pause");
return(0);
}

C) the mets are just playin with the competition thus far

1. Use [c0de] and [/c0de] tags
2. Read the FAQ, its in there
3. Use specific topic titles
4. There are tons of things you can do, I use

Code:

#include <string>
...
    system("Pause");
    return 0;

But that is partially compiler dependent

I assume you're using a console considering that happens.

You have a coouple of choices, you can include <conio> and use the getch() funtion:

Code:

#include <iostream>
#include <conio>
using namespace std;

int main()
{
   cout << "Hello, world!" << endl;
   getch();
   return 0;
}
// The getch function pauses the program until a key is pressed.

I think you can also use the <iostream> member function get() to pause, I'm no so sure about that though.

Code:

#include <iostream>
using namespace std;

int main()
{
   cout << "Hello, world!" << endl;
   cin.get();
   return 0;
}

Hope that helps, have fun, and don't give up!

Edit: Dangit I got beaten, oh yeah Geo-Fry, I don't think that you should use 1337 in the code tags...

lovely how you show code tags with no indentation.

What does the

Code:

using namespace std;

Thing mean

What does the

This question has been answered before!!!! Look around at sources to find the answer.

check the FAQ. Many of the questions in this thread will be found in there.

hey... i've never had this problem before... the window always stays open unless i close it...

**Noobie** · 05-15-2003

If u open it in command prompt itll stay open, but if u open it as an executable itll close when its finished unless u program it not to.

Also VC++ (dunno about any others) adds a pause at the end of programs in debug build automatically, but not in release build.
