Declaring main function

Hi,
I was looking at some of my old code that runs under MS-DOS 6. I noticed that the beginning of my programs looked like this:

/* Begin hello.cpp */

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

using namespace std;

int main(int argc, char *argv[])
{

cout << "Hello World!\n";
system("PAUSE");
return 0;
}

The above code reminds me of Java's "public static void main( String args[] )"


I have some programs that use "void main()" instead of "int main(int argc, char *argv[])". I don't know where I learned to put int "argc, char *argv[]" inside the main function.

I never pass parameters to the main function. Has anybody seen something like this before? Is one method of declaring a main function better than the other? Or, when would I need to use "int main(int argc, char *argv[])" ?

Edit:</B Clarified first sentence. Thanks to everyone who replied! I gotta go now.
