prog.cpp: In function ‘int main()’:
prog.cpp:13:13: error: ‘cout’ was not declared in this scope
cout<<x<<") Lunedi";

prog.cpp:13:13: note: suggested alternative:
In file included from prog.cpp:1:0:
/usr/include/c++/4.8/iostream:61:18: note: ‘std::cout’
extern ostream cout; /// Linked to standard output

Quindi hai corretto ... ?
