#include <iostream.h>;
main(){
        cout<<"hello, good guy."<<endl;
        return 0;
}

$ g++ test.cpp

In file included from /usr/include/c++/3.2/backward/iostream.h:31,
                 from test.cpp:1:
/usr/include/c++/3.2/backward/backward_warning.h:32:2: warning: #warning This fi
le includes at least one deprecated or antiquated header. Please consider using
one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples in
clude substituting the <X>; header for the <X.h>; header for C++ includes, or <sst
ream>; instead of the deprecated header <strstream.h>;. To disable this warning u
e -Wno-deprecated.
