In particular, a class A capable of allocating memory for an object of type T must provide the types A::pointer, A::const_pointer, A::reference, A::const_reference, and A::value_type for generically declaring objects and references (or pointers) to objects of type T.
Provides the container adapter class templates std::flat_set and std::flat_multiset. <forward_list> Added in C++11 and TR1. Provides the container class template std::forward_list, a singly linked list. <inplace_vector> Added in C++26. Provides the class std::inplace_vector, analogous to std::vector with a fixed capacity defined at compile time ...
std::variant, a tagged union container [40] std::byte, allowing char to be replaced for data types intending to model a byte of data as a byte rather than a character [41] Logical operator traits: std::conjunction, std::disjunction and std::negation [42] <memory_resource> header, for polymorphic memory resources [43]
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]
The std::array is a fixed size container that is more efficient than std::vector but safer and easier to use than a c-style array. The std::forward_list is a single linked list that provides more space efficient storage than the double linked std::list when bidirectional iteration is not needed.
One common property of all sequential containers is that the elements can be accessed sequentially. Like all other standard library components, they reside in namespace std. The following containers are defined in the current revision of the C++ standard: array, vector, list, forward_list, deque.
C++23, formally ISO/IEC 14882:2024 [1], is the current open standard for the C++ programming language that follows C++20.The final draft of this version is N4950. [2] [3]In February 2020, at the final meeting for C++20 in Prague, an overall plan for C++23 was adopted: [4] [5] planned features for C++23 were library support for coroutines, a modular standard library, executors, and networking.
In C++, associative containers are a group of class templates in the standard library of the C++ programming language that implement ordered associative arrays. [1] Being templates, they can be used to store arbitrary elements, such as integers or custom classes.
