6.1 分析以下程序的执行结果
#includeiostream.h
class base
{
public:
base(){cout"constrUCting base class"endl;}
~base(){cout"destructing base class"endl; }

public:
subs(){cout"constructing sub class"endl;}
~subs(){cout"destructing sub class"endl;}
};
void main()
{
subs s;

所以输出为：
constructing base class
constructing sub class
destructing su...[ 查看全文 ]
