不使用虚析构函数的情况
源程序：
#include <iostream>
using namespace std;
class ABase{
public:
ABase(){
cout<<"ABase构造函数"<<endl;
}
~ABase(){
cout<<"ABase::析构函数"<<endl;
}
};
class Derived:public ABase{
public:
int w,h;
Derived(){
cout<<"Derived构造函数"<<endl;
w = 4;
h = 7;
}
~Derived(){
cout<<"Derived::析构函数"<<endl;
}
};
int main(){
ABase *p = new Derived();
delete p;
return 0;
}
运行结果：
