Notes If the iterator type (InputIt / ForwardIt) is mutable, f may modify the elements in the target range. For overload (1), f can be a stateful invocable object. The return value can be considered as the final …

This is a list of reserved keywords in C++. Since they are used by the language, these keywords are not available for re-definition or overloading. As an exception, they are not considered reserved in …

When determining whether an expression is a constant expression, copy elision is assumed not to be performed. The C++98 definition of constant expressions is entirely within the collpase box. The …

If an iterator falls into one of these categories and also satisfies the requirements of LegacyOutputIterator, then it is called a mutable iterator and supports both input and output. Non …

Parallel algorithms (since C++17) A parallel algorithm is a function template in the algorithms library with a template parameter named ExecutionPolicy or constrained by execution-policy (since C++26). …

It is of a class type with a constexpr destructor or (possibly multi-dimensional) array thereof, and for a hypothetical expression e whose only effect is to destroy the object, e would be a core constant …
