Language linkage

Provides for linkage between modules written in different programming languages. extern string-literal { declaration-seq(optional) } (1) extern string-literal declaration (2) 1) Applies the language specification string-literal to all function types, function names with external linkage and variables with external linkage declared in declaration-seq 2) Applies the language specification string-literal to a single declaration or definition. string-literal - The name of the

Lambda functions

Constructs a closure: an unnamed function object capable of capturing variables in scope. Syntax [ capture-list ] ( params ) mutable(optional) exception attribute -> ret { body } (1) [ capture-list ] ( params ) -> ret { body } (2) [ capture-list ] ( params ) { body } (3) [ capture-list ] { body } (4) 1) Full declaration. 2) Declaration of a const lambda: the objects captured by copy cannot be modified. 3) Omitted trailing-return-type: the return type of the cl

Iterator library

The iterator library provides definitions for five kinds of iterators as well as iterator traits, adapters, and utility functions. Iterator categories There are five (until C++17)six (since C++17) kinds of iterators: InputIterator, OutputIterator, ForwardIterator, BidirectionalIterator, RandomAccessIterator, and ContiguousIterator (since C++17). Instead of being defined by specific types, each category of iterator is defined by the operations that can be performed on it. This definition mean

Iterator

The Iterator concept describes types that can be used to identify and traverse the elements of a container. Iterator is the base concept used by other iterator types: InputIterator, OutputIterator, ForwardIterator, BidirectionalIterator, and RandomAccessIterator. Iterators can be thought of as an abstraction of pointers. Requirements The type It satisfies Iterator if. The type It satisfies CopyConstructible, and The type It satisfies CopyAssignable, and The type It satisfies Destructibl
