编译错误。在类B的构造函数中，缺少一个左括号，而在类A的定义中，构造函数和析构函数的定义不对齐。修正后的代码如下：

#include using namespace std; class A{ public: A(){ cout<<"A::A() called.\n";} virtual ~A(){ cout<<"A::~A() called.\n";} }; class B:public A{ public: B(int i){ buf=new char[i]; cout<<"B::B() called.\n";} virtual ~B(){ delete []buf; cout<<"B::~B() called.\n"; A *p=new B(15); fun(p); } private: char buf;}; void fun(Aa){ cout<<"May you succeed!"<<endl;} int main(){ A *a=new B(10); delete a; return 0; }
