]]>C++中析构函数可以为纯虚吗?http://www.cppblog.com/cooleaf/archive/2006/05/03/6598.htmlcooelafcooelafWed, 03 May 2006 13:19:00 GMThttp://www.cppblog.com/cooleaf/archive/2006/05/03/6598.htmlhttp://www.cppblog.com/cooleaf/comments/6598.htmlhttp://www.cppblog.com/cooleaf/archive/2006/05/03/6598.html#Feedback8http://www.cppblog.com/cooleaf/comments/commentRss/6598.htmlhttp://www.cppblog.com/cooleaf/services/trackbacks/6598.htmlclass CBase
{
public:
    CBase()
    {
        printf("CBase()\n");
    }
    virtual ~CBase() = 0;
};
答案是可以，那么这样实现的目的是什么呢？当然是避免实例化。
但因为派生类不可能来实现基类的析构函数，所以基类析构函数虽然可以标为纯虚，但是仍必须实现析构函数，否则派生类无法继承，也无法编译通过。
