operator!=

Tests if the set or multiset object on the left side of the operator is not equal to the set or multiset object on the right side.

operator<

Tests if the set or multiset object on the left side of the operator is less than the set or multiset object on the right side.

operator<=

Tests if the set or multiset object on the left side of the operator is less than or equal to the set or multiset object on the right side.

operator==

Tests if the set or multiset object on the left side of the operator is equal to the set or multiset object on the right side.

operator>

Tests if the set or multiset object on the left side of the operator is greater than the set or multiset object on the right side.

operator>=

Tests if the set or multiset object on the left side of the operator is greater than or equal to the set or multiset object on the right side.

swap

Exchanges the elements of two sets or multisets.

set Class

Used for the storage and retrieval of data from a collection in which the values of the elements contained are unique and serve as the key values according to which the data is automatically ordered.

multiset Class

Used for the storage and retrieval of data from a collection in which the values of the elements contained need not be unique and in which they serve as the key values according to which the data is automatically ordered.

allocator_type

A type that represents the allocator class for the set object.

const_iterator

A type that provides a bidirectional iterator that can read a const element in the set.

const_pointer

A type that provides a pointer to a const element in a set.

const_reference

A type that provides a reference to a const element stored in a set for reading and performing const operations.

const_reverse_iterator

A type that provides a bidirectional iterator that can read any const element in the set.

difference_type

A signed integer type that can be used to represent the number of elements of a set in a range between elements pointed to by iterators.

iterator

A type that provides a bidirectional iterator that can read or modify any element in a set.

key_compare

A type that provides a function object that can compare two sort keys to determine the relative order of two elements in the set.

key_type

The type describes an object stored as an element of a set in its capacity as sort key.

pointer

A type that provides a pointer to an element in a set.

reference

A type that provides a reference to an element stored in a set.

reverse_iterator

A type that provides a bidirectional iterator that can read or modify an element in a reversed set.

size_type

An unsigned integer type that can represent the number of elements in a set.

value_compare

The type that provides a function object that can compare two elements to determine their relative order in the set.

value_type

The type describes an object stored as an element of a set in its capacity as a value.

begin

Returns an iterator that addresses the first element in the set.

clear

Erases all the elements of a set.

count

Returns the number of elements in a set whose key matches a parameter-specified key.

empty

Tests if a set is empty.

end

Returns an iterator that addresses the location succeeding the last element in a set.

equal_range

Returns a pair of iterators respectively to the first element in a set with a key that is greater than a specified key and to the first element in the set with a key that is equal to or greater than the key.

erase

Removes an element or a range of elements in a set from specified positions or removes elements that match a specified key.
