![Effective STL中文版 - [美] Scott Meyers](https://static.book345.com/covers/s/9787302126959.jpg)
书籍介绍
这不是一本教你如何使用STL的入门书，而是一本写给已经踩过坑的人的经验之书。Scott Meyers没有从容器、迭代器的基础用法讲起，而是直接切入那些真正容易出问题的地方：为什么vector默认优于list，何时又必须切换；erase-remove idiom为何是清理元素的最佳方式；容器里存指针时如何避免内存泄漏；拷贝语义背后隐藏的容量与性能陷阱。全书50个条款，每个都追问“为什么”——分析问题的来源与解决方案的优劣，而非简单给出结论。它适合有一定STL使用经验、愿意反复查阅的读者，读时需要边读边实践，否则很容易“看完就忘”。它不是工具手册，而更像一份关于“如何正确使用STL”的圣经注释，值得放在手边随时翻检。

精彩摘录
- "拷进去,拷出来。这就是STL的方式。... ,拷贝对象是STL的方式。"
- "To avoid resource leaks when you have containers of pointers that should be deleted, you must either replace the pointers with smart reference-counting pointer objects (such as Boost's shared_ptr) or you must manually delete each pointer in the container before the container is destroyed."
- "1.the erase-remove idiom is the best way to get rid of elements with a specific value when c is a vector, string, or deque."
- "2.the remove member function is the best way to get rid of elements with a specific value when c is a list."
- "*To eliminate all objects in a container that have a particular value: If the container is a vector, string, or deque, use the erase-remove idiom. If the container is a list, use list::remove. If the container is a standard associative container, use its erase member function. *To eliminate all obje"
- "The expression vector<Contestant>(contestants) creates a temporary vector that is a copy of contestants: vector's copy constructor does the work. However, vector's copy constructor allocates only as much memory as is needed for the elements being copied, so this temporary vector has no excess capaci"
- "That's why it makes sense to consider using a sorted vector instead of an associative container only when you know that your data structure is used in such a way that lookups are almost never mixed with insertions and erasures."
- "If you're updating an existing map element, operator[] is preferable, but if you're adding a new element, insert has the edge."
用户评论
心血来潮mark下老早前读过的书
scott meyers “effective三部曲”之三
教人如何正确使用stl库的经验之谈，还不错的~~
一身冷汗，我是用了多少野路子的STL用法。后面某些 functor 在 c++ 11/14/17 里已经 deprecated ，需要找本新的书看了。当然，我们线上还是老旧的 gcc
经典，STL用户必读
快速了解stl的好书。书摘后续从博客整理到豆瓣上来。
不读过这本书不能谈自己会用STL
scott的有些地方自我矛盾，比如对于最佳实践的迭代器，一会说使用const，一会说使用一般迭代器，不知道是不是翻译的问题。确实是建议直接看STL源码
c++之复杂是我生平仅见
虽然有些条目确实是没意思，但是总体，真是，爽。读的时候心里一直在叫，我勒个去，还能这样。
