C++: string_view: Deep dive Jasmine Lopez Prithvi Okade 1Topics • Motivation • Performance benefits & basics • string_view: Constructors, useful functions • string vs. string_view and their interoperability interoperability • When to use string_view • Using string_view safely • Intro to span • span vs. string_view • Case study of an optimization using string_view. 2Motivation • Consider a function foo will end up calling “2”. And the code will miss the niceties of using the string API set. string_view helps in resolving this problem elegantly.Motivation 4 void foo(const std::string& str); void foo(const

Answer:

两本应该是够用了。不然就再加上一本SDK 书籍， 这样子应该是可以打个基础了。 CCA.bbs@cis.nctu.edu.tw：函数名称可以查help，重要的是C++ 的观念。另外就是要了 解MFC 里的Document/View/Frame，以及Dynamic Creation, Message mapping 等等。 深入浅出MFC 第二版对这些部份都有很深入的探讨，把MFC 里的一些机制直接trace code 加以说明。 程序设计模型（注2）息息相关之特殊性质（注3）的 实作方式。 注1：此指runtime type information、dynamic creation、persistence、document/view¡ K。 注2：此指message based、event driven 之programming model。 注3：此指message mapping、command routing ¡ K。 Document/View 支撐你的應用程式 / 419 利用 Visual C++ 工具完成 Scribble step0 / 423 骨幹程式使用哪些 MFC 類別？ / 423 Document Template 的意義 / 430 Scribble 的 Document/View 設計 / 436

This means that clients can fetch packages from, as well as upload packages nor create the packages. The packages are created by the client, and if binaries are built from sources, that compilation is also done by the client application. 3 Conan Documentation, Release 2.5.0 The the image above are: • The Conan client: this is a console/terminal command-line application, containing the heavy logic for package creation and consumption. Conan client has a local cache for package storage
