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 the above program, we create a set with name s values {3, 5, 2, 1}. Syntax. The set container is defined as std::set class template inside <set> header file.. set <T, comp> s;. where, T: Data type of elements in the set. s: Name assigned to the set. comp: It is a binary predicate function that tells set how to compare two elements.It is used to sort set in custom order.

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).

C++ Standard Library Set - Online Tutorials Library

Returns the number of elements with matching value in the set container. 2: set::find. Searches the set container for value and returns an iterator to it if found, else returns an iterator to set::end. 3: set::lower_bound. Returns an iterator pointing to the first element in the set container which is not considered to go before value. 4: set ...

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

A set either does or doesn't contain an instance of each possible key value. For example, a set of integers might contain the values {0, 1, 5}. A value (e.g. 5) can't be contained more than once in the set (if you call the set's insert method more than once for a given key value, the set will still contain only one instance of that key value).

Exceptions. Calls to Allocator::allocate may throw. [] NoteAfter container move construction (overload ()), references, pointers, and iterators (other than the end iterator) to other remain valid, but refer to elements that are now in * this.The current standard makes this guarantee via the blanket statement in [container.reqmts]/67, and a more direct guarantee is under consideration via LWG ...

Understanding and Using std::set in C++ - Machinet

The std::set is a part of the C++ Standard Library and is defined in the <set> header. It is an associative container that contains a sorted set of unique objects. The primary characteristics of std::set are: Elements are stored in a sorted order. Each element is unique; duplicate elements are not allowed.
