Can't even get the pre-made HelloWorld to work [message #1095418]

So, first let me just say I've used Eclipse for Java for several years, but now that I'm trying to get to learn C++, it's all confusion.

I went ahead and installed all the packages I need from MinGW, and went through the Eclipse help topic about setting up, building, and running the example HelloWorld program.

There aren't any errors or anything, but when I run it, the Console goes straight to terminated, I don't see anything print.

I'm just so confused. There's a lot more stuff to do to get a simple program running than I'm used to from Java.

Dear Johnson Joe

One should normally provide the code for problems as it is now impossible to see where you could've gone wrong, lucky it is a simple task and can be accomplished like so:

//A header that includes I don't know what but it does seem to be required as it is in every newly created document Smile

#include "stdafx.h"

//Provides standard input output methods
#include <iostream>

//Allows the calling of functions within the iostream (As far as I know this is how it works)
using namespace std;

int main()
{
//Outputs Hello world! to the console. the "endl" function moves the cursor to the next line.
cout << "Hello world!" << endl;

//Prevents the console from self-terminating and presents the user with the "Press any key to continue..." scenario.
system("PAUSE");

//Returns a value of 0 which normally means the program executed successfully.
return 0;
}

Try adding the MinGW bin path to the PATH env variable, typically C:\MinGW\bin. See
