在C#中,许多对象自动实现了clone函数,在C++中,要拷贝一个对象,除了自定义一个拷贝构造函数来实现对象复制外,还可以像C#中那样实现一个clone函数,这需要借助编译器实现的一个隐藏拷贝构造函数,这样的做法,更省心. #include "stdafx.h" #include <iostream> class CA { public: int value; CA* clone() const { return new CA( *this );} //仅一个构造函数 CA
Clone an undirected graph. Each node in the graph contains a label and a list of its neighbors. OJ's undirected graph serialization: Nodes are labeled uniquely. We use # as a separator for each node, and , as a separator for node label and each neigh

总所周知 php 的 clone方法 拷贝一个对象 而且还是所谓的浅拷贝 一时迷茫 今天终于整明白了 <?php class a { pulic $data; function __construct(){ $this->data = new DateTime("2014-07-05", new DateTimeZone("UTC")); } }$cls = new a();$cls->data; // 这个data的值实际上是一个引用//$s =
