In daily development, we sometimes need to construct a Map Note: It is too difficult to implement 　　Multimap The Multimap of Guava provides a data structure that conveniently maps a key to multiple values. This allows us to easily and elegantly implement the complex data structure above, so that we can focus on implementing business logic rather than on the data structure, next, let's take a look at the

Summary: The Multimap container for the standard library is very similar to the Map association container-but MULTIMAP allows duplicate keys. This feature makes Multimap more useful than you might think. This article will discuss it. In the article "Using // 注: 伪码 multimap phonebook.insert("Harry","8225687"); // 家里

In the article "Using Note: Pseudo code Multimap Phonebook.insert ("Harry", "8225687"); Home phone Phonebook.insert ("Harry", "555123123"); Unit Telephone Phonebook.insert ("Harry", "2532532532"); Mobile phone The ability to store duplicate keys in Multimap greatly affects its interface and use. So how do you create an associative container for a non unique key?

create a map object* 3. multimap (const multisetr ); // multimap * 4. multimap (first, last );* 5. multimap (first, last, const key_compare Comp );** // Example:* Pair * Pair * Pair * Pair * Pair * Multimap *

In the Use the In this article, we discuss the map associated container in the standard library. But that is only part of the map container. The standard library also defines a multimap container, which is similar to map, except that it allows duplicate keys. This attribute makes multimap more useful than expected: for example, a person with the same phone book c

cases, the same IP address will be associated with multiple URLs. All these URLs point to the same site. In this case, you should use multimap instead of map. For example:#include #include multimap Use the insert () member function instead of the subscript operator to insert an element. Insert () has a pair type parameter. In "use DNS_dae

Detailed map, Multimap, Unordered_map, unordered_multimapI believe that a lot of students and I just contact C + + STL, is deeply attracted by it. But trying to understand each template class is not an easy task. We should be on the vector, list, stack, queue and other classes to understand, so today detailed introduction of the next few very powerful but a little less understood class map, Multimap, Unorde

The element first member variable is also called the keyword, and its type is key. The second member variable is also called a value, and the type is T. The elements in the

The project needs to adopt a one-to-many mapping relationship, the original has not used Multimap, learning a bit, feeling more easily than imagined, a small example, demonstrating the use of multimap. #include #include using namespace Std; void Test_multimap (){Construct test data for MultimapMultimapExample.insert (Make_pair ("A"), String ("11"));Example.inse

get the same value with * (RET.FISRT). The element value of the 2) set is its key value itself. The map has key and value 3) set to sort the elements sequentially. II, 1) multiset can store the same elements. 2) Insert returns an iterator. 3) Other same set Third, 1) Map storage elements are formatted key and value values. A map is a special set, all of which are pair 2) can find keywords based on key. Almost all operations against the map are based on the key. For

STL practice and analysis-multimap and multiset Introduction: In the map and set containers, a key can only correspond to one instance, while the multiset and multimap types allow a key to correspond to multiple instances. The multimap and multiset types have the same header file definition as the corresponding single-element version: map and set header files. T

function and the clear function.Traversal of elementsThe traversal of the map element accesses the element in addition to the array of key values, and can be accessed using an iterator.#include It can be seen from the results that, although it is an unordered insertion, the result of the traversal is orderly.Searching for elementsUse the find function to search for an element with a certain key value.#include Map also provides other functions, empty, size, swap, Lower_bound, Upper_bound, Equal_

Map and multimap are both self-contained find () and can be searched without generic algorithm. In fact, when both container and algorithm provide methods, we should first test the container self-belt method. Because algorithm still needs iterator to test the generic model, but the container self-belt method is tailor-made, therefore, the compaction speed is faster. There are three methods to list all values of a key in
