The problem that i couldn't know if the mistake from the code or from the compiler?
i have been setup cygwin.........as starting to learn Linux and into it
as a start to learn c++
i want to compile a (hello world) code
==================
#include<iostream.h>
void main()
{
cout<<"helloworld";

}
===================
but when i try to compile it with g++

i received the following message :-
=+=+==+=+==+=+==+=+==+=+==+=+==+=+==+=+==+=+=
=+=+==+=+==+=+=+==+=+==+=+==+=+==+==+=+==+=+=
$ gcc hello_world.cpp

In file included from /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/backward/iostream.h:31,

from hello_world.cpp:1:

Hi TarekSliem,

the solution is contained in this part:

Just use

Code:: #include<iostream>

The headers with .h are old style and should not been used anymore.
