std::execution: Inclusive ScanDecember 2, 2024 - 10:30 am
Inclusive scan solves problems related to range queries, such as calculating the sum of a range of elements in an array. It is also used in range minimum queries and various other algorithms. Before I present the asynchronous inclusive scan, I introduce the inclusive scan, aka prefix sum. Prefix Sum In computer science, the prefix […]
std::execution: Asynchronous AlgorithmsNovember 25, 2024 - 9:06 am
std::execution supports many asynchronous algorithms for various workflows. Presenting proposal P2300R10 is not easy. First, it is very powerful, and second, it is very long. Therefore, I concentrate on specific aspects of the proposal. What are the priorities of this proposal? Priorities The terms execution resource, execution agent, and scheduler are essential for the understanding […]
std::executionNovember 18, 2024 - 9:03 am
std::execution, previously known as executors or Senders/Receivers, provides “a Standard C++ framework for managing asynchronous execution on generic execution resources“. (P2300R10) Side Note Change of plans. My original plan was to present the C++26 library after the core language. However, the implementation status of the library is not good enough. Therefore, I decided to continue […]
C++26 Core Language: Small ImprovementsNovember 4, 2024 - 8:34 am
There are more small improvements in the C++26 language, which you should know. static_assert extension First, here’s the syntax of static_assert in C++11: static_assert(compile time predicate, unevaluated string) With C++26, the string can be a user-defined type having the following properties: static_assert can now be used with a format string. Here’s a nice example from […]
Placeholders and Extended Character SetOctober 28, 2024 - 10:19 am
Placeholders are a nice way to highlight variables that are no longer needed. Additionally, the character set of C++26 will be extended. Placeholders Structured bindings are a C++17 feature that allows you to bind multiple variables to the elements of a structured object. The following program demonstrates using tuples and structured bindings to return and […]
Contracts in C++26October 21, 2024 - 9:54 am
Contracts allow you to specify preconditions, postconditions, and invariants for functions. Contracts should already be part of C++20 but were removed in the standard meeting in Cologne. Here is what Herb Sutter said about contracts on Sutter’s Mill: “contracts is the most impactful feature of C++20 so far, and arguably the most impactful feature we […]
