"<<endl; } example(int n) { i=n; cout<<"Constructing: "<<i<<endl; } ~example() { cout <<"Destructing: "<<i<<endl; } int get_i() { return i; } private: int i; }; int sqr_it(example o) { return o.get_i()* o.get_i(); } int main() { example x(10); cout<<x.get_i()<<endl; cout<<sqr_it(x)<<endl; return 0; }
