std:: set - C++ Users

Sets are containers that store unique elements following a specific order. In a set, the value of an element also identifies it (the value is itself the key, of type T), and each value must be unique.The value of the elements in a set cannot be modified once in the container (the elements are always const), but they can be inserted or removed from the container.

std::set - cppreference.com

std::set is an associative container that contains a sorted set of unique objects of type Key.Sorting is done using the key comparison function Compare.Search, removal, and insertion operations have logarithmic complexity. Sets are usually implemented as Red–black trees.. Everywhere the standard library uses the Compare requirements, uniqueness is determined by using the equivalence relation.

Set in C++ STL - GeeksforGeeks

Explanation: In this program, we create two sets: Statement set<int> s1 creates an empty set s1.This is called default initialization.; Statement set<int> s2 = {5, 1, 3, 2} create s2 with 4 elements using initializer list.; To know more ways to initialize a set in C++, refer to the article - Different Ways to Initialize Set Basic Operations. Here are the basic operations that can be performed ...

C++ Tutorial - std::set

std::set. std::set is an associative container in C++ that stores a collection of unique elements, following a specific order. It allows fast retrieval, insertion, and deletion of elements. 1. Characteristics of std::set - Unique Elements: No duplicate values are allowed; each element in the set must be unique. - Sorted Order: Elements are stored in a specific order (usually ascending).

What is a "set" in C++? When are they useful? - Stack Overflow

Sets "in general" are a (very fundamental) concept in mathematics.. STL's set is based on the mathematical concept of a set: it's a collection of unique members, or a "Unique Associative Container" in STL terminology. The one slightly odd thing is that it sorts elements (in a mathematical set, there is no "order" to the elements). Some STL implementations also support a hash_set, which is very ...

C++ Standard Library Set - Online Tutorials Library

A set is an Associative container which contains a sorted set of unique objects of type Key. Each element may occur only once, so duplicates are not allowed. There are four kind of Associative containers: set, multiset, map and multimap. The value of the elements in a set cannot be modified once in the container, i.e., the elements are always ...

set::set - C++ Reference

Construct set. Constructs a set container object, initializing its contents depending on the constructor version used: explicit set ( const Compare& comp = Compare(), Allocator& = Allocator() ); Default constructor: constructs an empty set object, with no content and a size of zero. template <class InputIterator> set ( InputIterator first, InputIterator last, const Compare& comp= Compare ...
