Default c++ compiling hello world

As you can guess i am totally new in this theme. I do not understand error message, so i am asking for your help. Why can't i compile this program:
Code:
#include <iostream.h>

int main()
{
  cout << "Hello World!\n";
  return 0;
}
Error:
Code:
%gcc n01-hello.cpp
In file included from /usr/include/c++/3.4/backward/iostream.h:31,
                 from n01-hello.cpp:1:

Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <iostream> instead of the deprecated header <iostream.h>. To disable this warning use -Wno-deprecated.
