Hi everyone!!
I was trying to do a "Hello World" C++ program in emacs but I have a little problem:

The Hello World code is:

#include <iostream.h>
int main()
{

cout << " Hello World " << endl;
return(0);

}

and when I compile appear me alot of error and warnings but when I compile in to M$ Visual C++ works fine.

I made a calculator in emacs and works fine I don't know what I made wrong!! Thanks for Answers!!

Don't know what's not working, but this might help as an additional reference:

I think it would only give a lot of warning messages, not error messages. You should be able to compile and it should work.
These warning messages come out because you are using the old library. Try this code and should be ok.
Using the new library "iostream", without ".h".

the code is:

#include <iostream>
using namespace std;

int main()
{

cout << " Hello World " << endl;
return(0);

}

Hi moeminhtun!!

I tryed to use the new library and always give the a lot of warnings and just 1 error you have reason, but always give me troubles works with emacs, when I do whatever program always give me warnings and errors I dont know why? Thanks a Lot..
