Ciao a tutti
Ho provato a fare un semplicissimo programma in C++
Ecco il codice:
codice:
#include <iostream.h>
int main(void) {
	int num = 0;
	cout << "PROVA";
	cin >> num;
}
Ho provato a compilarlo facendo gcc prova.cpp
Ecco il risultato:
codice:
damiano@damiano:~$ gcc prova.cpp
In file included from /usr/include/c++/3.3/backward/iostream.h:31,
                 from prova.cpp:1:

Please consider usingone 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 <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated.
