The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
sort is a generic function in the C++ Standard Library for doing comparison sorting.The function originated in the Standard Template Library (STL).. The specific sorting algorithm is not mandated by the language standard and may vary across implementations, but the worst-case asymptotic complexity of the function is specified: a call to sort must perform no more than O(N log N) comparisons ...
Flexible array members were officially standardized in C99. [4] In practice, compilers (e.g., GCC , [ 5 ] MSVC [ 6 ] ) provided them well before C99 was standardized. Flexible array members are not officially part of C++ , but language extensions [ 7 ] are widely available.
an associative array; allows mapping from one data item (a key) to another (a value). Type of key must implement comparison operator < or custom comparator function must be specified; such comparison operator or comparator function must guarantee strict weak ordering, otherwise behavior is undefined. Typically implemented using a self-balancing ...
array implements a compile-time non-resizable array. vector implements an array with fast random access and an ability to automatically resize when appending elements. deque implements a double-ended queue with comparatively fast random access. list implements a doubly linked list. forward_list implements a singly linked list.
C++ (/ ˈ s iː p l ʌ s p l ʌ s /, pronounced "C plus plus" and sometimes abbreviated as CPP) is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup.
This allows also for array members in class-type NTTP. Floating-point types, [133] pointers and references and unions and union-like classes (class types containing anonymous unions) are now allowed as NTTP. Function identity now also includes trailing requires-clauses (P1971) Constrained non-template functions have been removed
Folds can be regarded as consistently replacing the structural components of a data structure with functions and values. Lists, for example, are built up in many functional languages from two primitives: any list is either an empty list, commonly called nil ([]), or is constructed by prefixing an element in front of another list, creating what is called a cons node ( Cons(X1,Cons(X2,Cons ...
