to you guys, this should be easy, but to a newbie, this is like rocket science.


So I just brought a book today. called Teach yourself C++. It came w/ the Dev C++ compiler, which I installed. I did exactly what the book told me to do I put in the HelloWorld code, and compiled it. It ran completely fine. But when I exectuted it, I didn't get an output. All that happened was my compiler minizmized really really quick, and popped back up. no output, no nothing.

But.........for simplicity sake, I saved my projects on my desktop, so after trying to execute it, 3 or 4 new files appeared on my desktop. That's all I got........

hmm....so if I can't even run the very first program, it's kind of pointless to go on further into the book no?

help

I do not know C++ so I cannot help with actual code but I do know your desktop is a unique animal and can cause many unusual problems when is code sitting on it and being executed from it. You may try creating a folder and moving all the code into the folder then try executing it from there. You may also consider moving the folder to your Documents.
Just a thought!

hi Dave,

yea, it turns out that it didn't work. I created a folder inside my C drive called "codes" and saved my projects in there.

Again, the program compiled fine, but when it came time to actually run it, all my compiler did was minimize really really quick and maximize back on screen.

again, 6 files appeared on my codes folder

Project.dev
Project~2.exe
Project1.cpp
Project1.o
rsrc.o
Rsrc.rc

dont know........

heck, here is the code that I put.
===========================================

#include <iostream>

int main()
{
std::cout << "hi\n";
return 0;

}
=================================

Hiya

I have used Borland to learn how to compile, so this is the basics for the hello World:

You say you use this:

==============================================

#include

int main()
{
std::cout << "hi\n";
return 0;

}

==============================================

Now, is that it? What you don't have in there is a getch. For example, try this. Also, not sure if you have the standard #includes in, but I'll put a simple program in:

==============================================

#include condefs.h
#include stdio.h
#include stdlib.h
#include iostream.h
#include conio.h
#pragma hdrstop


int main(int argc, char **argv)
{
cout << "hello World!" << endl;

cout << endl << "Press any key to continue...";
getch();
return 0;
}

==============================================

*edit* Okay. The words condefs.h, stdio.h, stdlib.h, iostream.h, conio.h and hdrstop need to have the <'s and >'s surrounding them.

There are 2 spaces in front of the cout to return. In other words, as I can't get the spaces to post, just put the {'s in, and the beginning of each line in between, add 2 spaces. if you get my drift

As I say, the #includes may already be set up, but the getch produces a keystroke type of effect. Also, you don't have any endl's in there.

hmm, do you tink it's the compiler? Is there a different I should/could try?

Eddie,

I copied your code onto my compiler, and it got the same result....

[eddie5659]

Whats the complier you're using?

In the book, what does it suggest for the Hello world program? Was that all it gave, when you posted the code.


Did you put those spaces in, that I tried to mention?

eddie

[eddie5659]

Hang on, there's bits missing in mine

I'll edit it, so look back at it in a minute

Okay, all done

eddie

[semidevil]

hm........that's wierd......still the same problem. I dno't know.........I"m getting frustrated now

[DJ P@CkMaN]

what OS are you using? i have the same problem in WinXP and im not sure if this would happen in other OSes. try copying the EXE file (Project~2.exe) to C:\ and click Start>Programs>Accessories>Command prompt or MS-DOS Prompt and type

C:\Project~2.exe

and it should work fine

good luck

Eddie - is this what you're chasing?
----------
#include&nbsp;&lt;condefs.h&gt;
#include&nbsp;&lt;stdio.h&gt;
#include&nbsp;&lt;stdlib.h&gt;
#include&nbsp;&lt;iostream.h&gt;
#pragma&nbsp;hdrstop

int&nbsp;main(int&nbsp;argc,&nbsp;char&nbsp;**argv)
{
&nbsp;&nbsp;cout&nbsp;<<&nbsp;"hello&nbsp;World!"&nbsp;<<&nbsp;endl;

&nbsp;&nbsp;cout&nbsp;<<&nbsp;endl&nbsp;<<&nbsp;"Press&nbsp;any&nbsp;key&nb sp;to&nbsp;continue...";
&nbsp;&nbsp;getch();
&nbsp;&nbsp;return&nbsp;0;
}
-------------
or more simply

#include <condefs.h>
#include <stdio.h>
#include <stdlib.h>
#include <iostream.h>
#pragma hdrstop

int main(int argc, char **argv)
{
  cout << "hello World!" << endl;

  cout << endl << "Press any key to continue...";
  getch();
  return 0;
}

You can view the source on this page to see how I did it.
As a side note - those spaces shouldn't matter to the compiler at all - they are merely readability issues and unless he's using precompiled headers and you feed the hdrstop a filename - I'd leave it out.

[DJ P@CkMaN]

hmmm.. ur making a simple task WAY more complicated. as i am new to C++ as well i understand what hes going through and you guys cant be helping

[eddie5659]

Sorry, DJ P@CkMaN, just lost myself in the moment. First reply in Developement....ever

semidevil:

I have Win2000, and the code that I put worked well. Whats the company that made the compiler?

The Project1.cpp looks like its the code, or at least the name of the program that you are trying to run.

hang on, just realised I have something missing in my code. I'll edit it again, so try it once more. left out conio.

[semidevil]

hmm.......I don't know. the compiler came w/ my book, and it is called Dev C++. I think you can d/load it too.

but yea, I dont' know. I still can't get hello world. The code HAS to be right because I just copied right out of the book.

btw, when you install a compiler on your pc, is that all you need to do? aer there special settings that I need to configure before getting it to work properly?

I dont' know, could there be a problem somewhere there?

[eddie5659]

Hiya

When I installed mine from Borland, that was all I had to do.

The bit of code that you have given right at the beginning: was that all that it said in the book?

Also, were the #include's already shown in the compiler?

eddie

[semidevil]

hmmm.......yea, that code was it. just those tiny 5 or 6 lines. As of matter of fact, the stuff that YOU typed got my head spinning! haha, j/k.

as for the #include <iostream>, no, I had to type that in myself....the project started out as a blank application.

as for any configurations, the reason I asked is that in my java class, I had to configure like my path in autoexec.bat and stuff like to get it to run. So I was wondering if C had anything like that all....
