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.

How to check that an element is in a std::set? - Stack Overflow

The single element version return a pair, with its member pair::first set to an iterator pointing to either the newly inserted element or to the equivalent element already in the set. The pair::second element in the pair is set to true if a new element was inserted or false if an equivalent element already existed.

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 ...

8) If nh is an empty node handle, does nothing and returns the end iterator.Otherwise, inserts the element owned by nh into the container, if the container doesn't already contain an element with a key equivalent to nh. key (), and returns the iterator pointing to the element with key equivalent to nh. key (regardless of whether the insert succeeded or failed).

Return value. A pair consisting of an iterator to the inserted element (or to the element that prevented the insertion) and a bool value set to true if and only if the insertion took place. [] ExceptionIf an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).[] ComplexitLogarithmic in the size of the container.
