Each C++ expression (an operator with its operands, a literal, a variable name, etc.) is characterized by two independent properties: a type and a value category. Each expression has some non-reference type, and each expression belongs to exactly one of the three primary value categories: prvalue, xvalue, and lvalue.| en.cppreference.com
This post is part of the Future Java Releases series. In this second post in the future of Java series, we will focus on a new feature of the JVM designed to improve performance. Project Loom - Virtual Threads Project Loom aims to deliver new and improved APIs and JVM enhancements for concurrency. Concurrency has famously been a hot topic for ages, since Moore’s law started to slow down a few years ago and chip makers started creating CPUs with multiple cores.| andreabergia.com
When certain criteria are met, the creation of a class object from a source object of the same type (ignoring cv-qualification) can be omitted, even if the selected constructor and/or the destructor for the object have side effects. This elision of object creation is called copy elision .| en.cppreference.com
C++20 Coroutines There seems to be a lot of confusion around the implementation of C++20 coroutines, which I think is due to the draft technical specification for C++20 stating that coroutines are a work in progress so we can’t expect full compiler and library support at this point in time. A lot of the problems probably arise from the lack of official documentation about working with coroutines. We have been given C++ syntax support for coroutines (the co_yield and co_return) but without [...| Sticky Bits - Powered by Feabhas
