有如下程序: #include <iostream> using namespace std class Obj { static int i public: Obj( ){i++} ~Obj(){i--} static int getVal( ){ return i} } int Obj::i=0 void f() {Obj ob2 cout<<ob2.getVal( ) } int main( ){ Obj ob1 f() Obj *ob3=ew Obj cout<<ob3->getVal( ) delete ob3 cout<<Obj::getVal( ) return 0 } 程序的输出结果是
