## The Main Points of C++ Misha ## Point Point, as in: ### 4.2 1. Just one point (dot) ## 3 -4 ### 1. Just one point (dot) • In floating-point literals 4.2 followed by suffix or exponent (e or p) informally to represent hierarchy.” 2. Two points -> colon ## 10 -12 ### 2. Two points -> colon • Class inheritance struct S : BaseClass { } ; ### 2. Two points -> colon • Class inheritance • Member 2. Two points -> colon • Class inheritance • Member access specifiers • Member initializer list struct S : BaseClass { S(int xx) : x(xx) {} private: int x; }; ### 2. Two points -> colon

## Customization Methods: Connecting User And Library Code Inbal Levi ## Who Am I? • A C++ Developer at Millennium. • Active member of ISO C++ work group (WG21): • Library Evolution Work Group Chair presents my views and opinions only. ## Outline Part 0: What is a Library Part I: What are Customization Points (+ Some History...) Part II: An overview of CPs methods (+ Some History...) Part III: Comparing library and users’ code. • Customization points are the answer! ## Part I: What Are Customization Points ## Part I: What Are Customization Points • “Customization Points” mentioned by Eric Niebler, in

"okay" now! ## What else is required for proxy iterators to work? ## Customization Point Objects ## This has always been an awkward pattern: 1 template 2 void Al std::swap; swap(t1, t2); // More algorithm ## Pre-C++20 • swap, begin, and end are “customization points”. • Special behavior for user types. • Used Argument-Dependent Lookup (ADL) to find user std::ranges::iter_swap • Improvement upon std::iter_swap from C++98. - Intentionally designed customization point for proxy iterators. • Used by all std::ranges algorithms that swap stuff. std::ranges::iter_swap

handle Keywords: co_return, co_await, co_yield(not covered here) • awaitables, awaiters • Customization point and how functions are compiled Before we dive into the system, I want to take 10 mins to Promise Object. It’s a user defined type. It is part of the coroutine frame. This is the major customization point for user to store persistent coroutine related data. Then we have coroutine handle. And retrieve both awaiter and awaitable according to certain rules. Then await on the awaiter. ## Customization point - How a compiler may work template struct task; task sum(int a, int

organized in a hierarchical directory structure of bases and overlays. A base is a directory with a customization.yaml file containing a set of resources and associated customizations. A base has no knowledge knowledge of an overlay and can be used in multiple overlays. An overlay is a directory with a customization .yaml file that refers to other Customize directories as its bases. An overlay can draw from multiple composes all resources from bases and can also add customizations on top of them. You can also write customization .yaml files that build on one another (for example, a base can refer to another base). Figure
