[C++] First Program

[a4r9]

Hello, this is my first C++ program. It should be pausing but does not pause. Instead it simply creates the window displaying the message and then quits. How can I make the window stay open to read the message? I'm using Dev-C++ under Windows 2k.

cout << "Hello World!" << endl;
         
cin.get();

I'm fairly new to C++ myself and your code works fine. I'm not quite sure what the problem is with your computer. I'm using Dev-C++ myself but running it in XP.

Works fine with CodeBlocks (mingw) too..

try replacing "cin.get();" with "System("PAUSE")"

In general, there's no way to make it pause.  system("pause") will only work on PCs.

Try to make a loop with do..while and check when user press enter for example.

Welcome to the forum a4r9!

Welldone on your first c++ program and keep going 

[a4r9]

Thanks ya'll, although it's still not working, still doing the same thing, I'm starting to think it's the OS

[Hotshot]

What is doing the same things?
What error did you have?
what OS do you have?

[a4r9]

Is still coming up with a screen then going away instantly either saying already compiling or source could not compile. And I have Windows 2000 sadly.

[Hotshot]

Strange.

try that as work very well with Visual C++ 2008 Express!

# include <iostream>
using namespace std;

int main()
{
cout <<"hello world";

// Pause the Screen
getchar();   // This line of code is from Programming C but still pause the screen and it is work!

return 0;
}


[a4r9]

That still doesn't work, I'm starting to think that maybe I should try it on my mom's computer, she runs XP, I miss it, was great for everything XD

[Hotshot]

The program I have used above on DEV C++(I have check that) and Visual C++ 2008 Express work very well on either XP and Vista too but not sure about Window 2000 thought. 

let me know how you get on thought when you go on XP testing your program

Sometimes cin.get() takes something from buffer (or something), I think I heard.

Try doing a cin.get(ch).get(ch);

#include <iostream>

int main()
{
std::cout << "Hello World" << std::endl;
char ch;
cin.get(ch).get(ch);
return 0;
}


I know it isn't pretty, but it should work. You would maybe be able to do cin.get().get(). I thought I could too, but g++ started whining about it.

Indeed it works in XP, it must be the operating system then.

Congrats dude on getting it fixed.

[Pixel_Outlaw]

Yes, I don't have any idea why it would not work on you other OS...

If you want a game based C++ book you might try C++ Programming for the Absolute Beginner just ignore the last chapter on DirectX as we all know it is one of the tendrils of the Microsoftoctopus. C++ for Dummies is also very extensive. After finishing Beginning C++ Game Programming I can honestly say that the later chapters of the book completely fall apart. The author stops commenting on code and starts introducing like 2 new concepts each exercise.

I learned all I know of C++ from Preacher/Traction's source code and the OpenGL API from http://nehe.gamedev.net/, though GLSL I learned from the Orange Book.
