Compile help?VC++

[|2eM!x]

okay, im just starting c++(today), can you explain to me how to compile/what im doing wrong here?

#include <iostream.h>

int main()
{
   cout << "Hello World!\n";
        return 0;
}

and it compiled without errors(i pressed the f7 button) and i found a exe file named cpp1.exe,

when i run it, it looks like a bat file, then closes..without saying anything..

what am i doing wrong? am i even in the right forum?

#include <iostream> //<iostream.h> is deprecated

int main()
{
     cout << "Hello World!\n";
     system( "pause" );
     return 0;
}

Try this.

#include <iostream> //<iostream.h> is deprecated

using namespace std;

int main()
{
     cout << "Hello World!\n";
     system( "pause" );
     return 0;
}

Sorry this should work.

cool, can you please explain the code, or could someone?

#include <iostream> //a header file that's part of the C(++) standard, containing declarations for various functions/types etc. you're gonna use (cout etc.)

using namespace std; //The namespace under which you're working, included here because all declarations in the standard headers are in this namespace

int main() //The program starts at this function, the function returns an int type
{
     cout << "Hello World!\n"; //Sends the string "hello world!" with a newline char on the end (making a new line) to the console output stream
     system( "pause" ); //Runs the system command pause (causing the press any key to continue text)
     return 0; //returns a 0, indicating the successfull termination of this program
}

Use Firefox or Opera to go here for a very long and thorough breakdown of the Hello application.

And get rid of the system("pause"). Either invoke the application by pressing Ctrl+F5 in the IDE, or use a console (Run->"cmd") to navigate to the output directory and call the application on the console. In both cases, the console will stay open and you see the output, without adding a non-portable and nonsensical piece of code.
