The multiset in C++ is a container in the STL that stores multiple identical elements in an ordered collection, automatically sorting them based on their values. It allows for duplicate elements while maintaining their order.<\/p>\n

The usage of multiset is similar to other STL containers, and it can be used by including the header file for multiset. Here are some common uses of multiset:<\/p>\n

    \n
  1. Create a multiset object.<\/li>\n<\/ol>\n
    std::multiset<int<\/span>> mySet; \/\/ \u521b\u5efa\u4e00\u4e2a\u5b58\u50a8int\u7c7b\u578b\u7684multiset<\/span>\r\n<\/code><\/pre>\n
      \n
    1. Insert elements:<\/li>\n<\/ol>\n
      mySet.insert<\/span>(10<\/span>); \/\/ \u63d2\u5165\u5143\u7d2010<\/span>\r\nmySet.insert<\/span>(20<\/span>); \/\/ \u63d2\u5165\u5143\u7d2020<\/span>\r\nmySet.insert<\/span>(10<\/span>); \/\/ \u518d\u6b21\u63d2\u5165\u5143\u7d2010<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Traverse through the multiset.<\/li>\n<\/ol>\n
        for<\/span>(auto<\/span> it = mySet.begin<\/span>(); it != mySet.end<\/span>(); ++it) {\r\n    std::cout << *it << \" \"<\/span>;\r\n}\r\n<\/code><\/pre>\n
          \n
        1. Remove elements:<\/li>\n<\/ol>\n
          mySet.erase<\/span>(10<\/span>); \/\/ \u5220\u9664\u5143\u7d2010<\/span>\r\n<\/code><\/pre>\n
            \n
          1. Search for an element:<\/li>\n<\/ol>\n
            auto<\/span> it = mySet.find<\/span>(20<\/span>); \/\/ \u67e5\u627e\u5143\u7d2020<\/span>\r\nif<\/span>(it != mySet.end<\/span>()) {\r\n    std::cout << \"Element found: \"<\/span> << *it << std::endl;\r\n} else<\/span> {\r\n    std::cout << \"Element not found\"<\/span> << std::endl;\r\n}\r\n<\/code><\/pre>\n
            Multiset allows for operations such as inserting, deleting, and searching elements while maintaining their order. When there is a need to store multiple identical elements and maintain sorting, multiset can be considered.<\/p>\n","protected":false},"excerpt":{"rendered":"
