Very Beginner Question

**[Namuan]** · 01-08-2004

Hi, I tried a tutorial and I am using Borland C++. I can't get it to run. Here is the source code :

Code:

//---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
#include <iostream.h>
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
        : TForm(Owner)
int main()
{
  cout<<"HEY, you, I'm alive!  Oh, and Hello World!";
  return 0;
}
//---------------------------------------------------------------------------

Any help would be great. Thanks

The problem is that you are trying to create a console program in a VCL app. When BCB opens up, do a "Close All", and then "New -> Console Wizard" (or "Console App" or something, depending on version). Then put your code there.

Thanks. I still can't run the program so I am obviously having some horrible errors. Is there a better place to start since the beginner tutorial isn't working? Hah..

Post your current code.

You could try the tutorials on cprogramming.com. Although they are somewhat outdated, they are still better than the ones you were reading...I don't know what that tutorial you were looking at is trying to accomplish, but it seems to have unnecessary lines of code and is also outdated. Here's a simple example program:

Code:

#include <iostream>

int main()
{
std::cout<<"Hello world!";
}

That should compile fine, assuming you have an up-to-date compiler.

If you are learning c++ from scratch, drop the book you have there and learn the fundementals first.
Here are 2 good tutorials to get you on your way.

sams c++ 21days
Swap the 21days to 21weeks for a more realisitic idea timescale.

Code:

//---------------------------------------------------------------------------

#include <iostream>

int main()
{
std::cout<<"Hello world!";
}

//---------------------------------------------------------------------------

With Borland that gives me the error, in console wizard mode, that says :
"[Linker error] Unresolved external '__InitVCL' referenced from C:\...\Lib\CP32MTI>LIB|crtlvcl
"[Linker error] Unresolved external '__ExitVCL' referenced from C:\...\Lib\CP32MTI>LIB|crtlvcl"

y? don't u try this code.

Code:

#include<iostream>
#include<conio.h>

using std::cout;
using std::endl;

int main()
{
    // display hello world message
    
    cout<< "Hello World:" <<endl;    

getch();

}

I got it to work. I had to uncheck VCL/CLX. I tried switching between the two instead of actually disabling both. It works now. Only think is that it closes before I can see it. How can I fix that?

**o0o** · 01-09-2004

The only prob u r facing at the moment is that your system doesn't pause so that u can see the output.

here try to include cstdlib in ur code.

Code:

#<iostream>
#include<cstdlib> // in older version try stdlib.h
int main()
{

code

system("PAUSE"); // pause the system to see output
return 0;

}
