More Effective C++ #@author: gr #@date: 2015-05-11 #@email: forgerui@gmail.com 一.仔细区别pointers和references 1.1. 初始化 指针可以不初始化,引用必须初始化为. 引用没有null reference,指针可以设为NULL. //指针初始化为0,NULL,nullptr char *str = 0; int a = 1; //引用必须初始化,int &b;是错误的 int &b = a;…
这是篇读书笔记,只记录自己的理解和总结,一般情况不对其举例子具体说明,因为那正是书本身做的事情,我的笔记作为梳理和复习之用,划重点.我推荐学C++的人都好好读一遍Effective C++ 系列,真是好书啊,对于学完C++ 基础知识的人,这是本高阶秘籍.值得注意的是 More Effective C++ 是以1997年的C++标准写的,那时候标准还不完善,20多年过去了,很多语言的漏洞和技术可能被新特性取代了,应该注意最终向新标准看齐. 笔记 条款1:仔细区别pointers 和 referen…

Pointers are like jumps, leading wildly from one part of the data structure to another. Their introduction into high-level languages has been a step backwards from which we may never recover. — Anthony Hoare 对指针可能有最让人误解和惧怕的数据类型,因此很多程序员喜欢躲避他们. 但是指针很重要…
