以下程序的输出是
class Base { public: Base(int j): i(j) {} virtual~Base() {} void func1() { i *= 10; func2(); } int getValue() { return i; } protected: virtual void func2() { i++; } protected: int i; }; class Child: public Base { public: Child(int j): Base(j) {} void func1() { i *= 100; func2(); } protected: void func2() { i += 2; } }; int main() { Base * pb = new Child(1); pb->func1(); cout << pb->getValue() << endl; delete pb; }
