Effective C++
内容简介
“c++程序员可以分成两类，读过effective c++的和没读过的。”世界顶级c++大师scott meyers这部成名之作，与这句话一道在全球无数读者间广为传颂。几乎所有c++书籍推荐名单上﹐《effective c++:改善程序与设计的55个具体做法:第3版》都会位列三甲。作者高超的技术把握力、独特的视角﹑诙谐轻松的写作风格﹑独具匠心的内容组织﹐都受到极大的推崇和仿效。
对于国外技术图书，选择翻译版还是影印版，常让人陷入两难。本评注版力邀国内资深专家执笔，在英文原著基础上增加中文点评与注释，旨在融合二者之长，既保留经典的原创文字与味道，又以先行者的学研心得与实践感悟，对读者阅读与学习加以点拨、指明捷径。
经过评注的版本，更值得反复阅读与体会。希望这《effective c++:改善程序与设计的55个具体做法:第3版》能够帮助您跨越c++的重重险阻，领略高处才有的壮美风光，做一个成功而快乐的c++程序员。

读书文摘
Class的设计就是type的设计 。重载函数和操作符、控制内存的分配和归还、定义对象的初始化和总结。。。
1. “促进正确使用”的方法包括接口的一致性，以及与内置类型的行为兼容。 2. “阻止误用”的方法包括建立新类型、限制类型上的操作，束缚对象值，以及消除客户的资源管理责任。 3. 使用shared_ptr支持定制型删除器；也可以用来自动解除互斥锁。
