Code:

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

int main(int argc, char *argv[])
{
cout<<Hello world.<<endl;
  
  system("PAUSE");	
  return 0;
}

Sorry in advance for wasting peoples time. I want to learn.

Hi,
There is no question of wasting time as here people are gathered to help. As far as your code is concerned, when I compiled your program it showed me errors which disappered when I tried this:

Code:

#include <iostream.h>
      #include <stdlib.h>
      using namespace std;
      int main(int argc, char *argv[])
      {
      cout<<"Hello world."<<endl;
      system("PAUSE");
      return 0;
      }

However, in output it shows this:
Hello world.
sh: PAUSE: command not found

If anybody can help here

Regards

"PAUSE" didn't work on your machine because its a Windows command, and you're using UNIX it appears. As for the other you're right just add:

using namespace std;

When you have errors in your program, it's always a good idea to post the error message that you got. Aren't you supposed to using namespace std?

Ok Banny,

Thanks :)

Code:

#include <iostream>
    #include <stdlib.h>
    using namespace std;
    int main(int argc, char *argv[])
    {
    cout<<Hello world!!!<<end1;  
    system("PAUSE");	
    return 0;
    }

This code:

should be:
[code=cpp]
cout<<"Hello world!!!"<<end1 ;
[/code]

You need quotation marks on each end of your literals.

**gzeng** · Jul 24 '07, 12:21 AM

First of all, the cout statement can not be compiled. Without puting the string into double quotes " ", the compilor will translate it as a variable. Yet, it is not defined. Secondly, Visual Studio 2005 did understant system.

**sherbert** · Oct 28 '07, 05:43 PM

right..

in the first bit, how come you have all that stuff in the brackets of int main?

you only need int main() then the { } brackets
cout<<Hello world.<<endl; for that bit, you need qoutation marks on the hello world

try copying and pasting this code:-

Code:

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

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

      system("PAUSE");
      return 0;
}

note: when you past it to the compiler, remove the blue 1,2,3,4,5,6,7,8 ,9 and 10 numbers before trying to compile or it wont work..

**oler1s** · Oct 28 '07, 07:16 PM

Sherbert, you dug up an old threat. Moreover, you have a limited understanding of C and C++ and are making mistakes that reflect your limited knowledge.

The "stuff" inside the main would be arguments, and for main, the two arguments are used to contain the command line arguments passed to the program. It is acceptable to use main() without the arguments when you don't care for the command line arguments. There are only two forms of main that are acceptable: int main() and int main(int, char**). Now you know about the second form.

Furthermore, you need to buy a recent C++ book, becaus <iostream.h> and <stdlib.h> are Pre-1999 C++ standard header forms. For all standard libraries, there is no .h. C headers have a c prefixed to them.

Hence, you should have <iostream> and <cstdlib>. Furthermore, everything in the standard library is in the std namespace. So either qualify cout, endl, and system with std:: or add a using namespace std; directive.
