  helloworld - 2 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

  The build log says you've got 2 errors in your program. In order to create a program, you MUST have 0 errors (and although not required, you should also have 0 warnings). So what are the 2 problems with your program

  #include <iostream.h> void main() { cout << "Hello world!"; }

  Where did you get this code from Was it from a book If so, it seems to be outdated. Although this used to be correct code (before 1998), it no longer is correct C++ code (since C++ became standard).

  1. It's #include <iostream>, NOT #include <iostream.h> (notice, no .h in the end).
  2. You cannot use cout until you pull in the std namespace. You either need to add using namespace std (or using std::cout), or prefix cout with std::.

  Here is a corrected version of this code:

  #include <iostream>

  int main()
  {

  using namespace std;
  cout << "Hello World";
  return 0;

  }

  I suggest you read Ayman's blog post on the topic.

  PS. If you're learning C++ from a book, I suggest you find a later edition of that book, one which was written to deal with standardised C++.

  YIkes...
  
  

  #include <iostream>
  int main()
  {
    using namespace std;
    cout << "Hello World";
    return 0;
  }

  
  that is my new code....and it still gives 1 error :F
  
  it says that cout is an unidentified identifier now I dont get what that means but at least now I only got 1 error... Im hopeless :G
  
  edit...: here is the error :
  
  ------ Build started: Project: hello world, Configuration: Debug Win32 ------
  Compiling...
  kokeilu.cpp
  c:\documents and settings\toni\my documents\visual studio 2005\projects\kokeilu\kokeilu.cpp(6) : error C2065: 'cout' : undeclared identifier

  If you wrote that cpp file from something other than Visual Studio, you'll need to use the File -> New -> New Project From Existing Code wizard. Follow the wizard. Browse to your cpp file, give your program a name, and when asked for the project type, choose a console application. Ignore the last two pages in the wizard, and press finish.

  Now you can click the green start button in the toolbar to build/debug your application

  It looks like your project consists of two files:

  1. helloworld.cpp (I know what this file is)
  2. kokeilu.cpp . What is this  What is the content of this file

  If kokeilu.cpp is not supposed to be part of your project, remove it from your project (using the Solution Explorer tab).

  here is my next problem...
  
  

  #include <iostream.h>
  
  void main()
  {
   cout << "Hello world!";
  }

  that up there is my code...now that I press the play button (debug/compile)... it gives me an error saying this :
  
  "unable to start program 'c:/documents and settings/toni/my documents/visual studio 2005/projects/debug/helloworld.exe'.
  
  the system cannot find the file specified."
  
  and before this I made a .cpp file in VS2005... saved it, then did what you said to do... after this I press the green button (as I already said...) and it says that it compiles... does all kinds of stuf... then I get that popup :( dunno really what to do
  
  ------ Build started: Project: helloworld, Configuration: Debug Win32 ------
