STL follow-up-set/multiset container
set container principle std::set is a container in the C++ standard library that provides an ordered, non-duplicate collection of elements. The implementation of std::set is based on balanced binary search trees (red-black trees). The following are the main features and implementation principles of std::set: Ordering: The elements in std::set are stored in a specific order […]
STL–vector container (construction, traversal, insertion and deletion, capacity size, data access, dynamic expansion, etc.)
vector Foreword In the past few days, I have used STL a lot when writing code, and I have also felt the power of STL, so I reviewed the content of STL again, and summarized and extracted some basic things and important content. This is a vector article . C++’s STL provides us with many […]

C++ STL(5) set container summary Directory C++ STL(5) set container summary 1. Introduction 2. Constructor and member functions 3. Conclusion 1. Introduction std::set in C++ is a container that provides an ordered, non-repeating collection of elements. The following is some introduction to the std::set container: Ordering: The elements in std::set are sorted in ascending order. […]
C++stl_list linked list
Linked lists have been learned as early as when we were learning data structures. When I was learning data structures, I implemented them in C language just like my last vector article. The code I wrote at that time was smelly and long, and I had to satisfy a lot of requirements. interface; future/my_road – […]

(STL hash) unordered_map
1. unordered series containers In C++98, STL provides a series of associative containers with red-black tree structures at the bottom, including set, multiset, map and multimap. The time complexity of query operations for these containers is O ( log N ) O(logN)O(logN), where N is the number of elements in the container. In order to […]
C++STL(2) list container summary
C++ STL(2) list container summary Directory C++ STL(2) list container summary I. Overview 2. Detailed introduction and usage 3. Conclusion 1. Overview std::list is a doubly linked list container provided by the C++ standard library. Unlike std::vector, std::list does not store elements based on continuous memory, but links each element through pointers. This gives std::list […]
C++STL_vector sequence table
We must have come into contact with vector when we were learning data structures before. It is the sequence table in our data structure. We have implemented it using C language before. my_road: my code (gitee.com) This is the code I use to implement vector in C language; we have to write a lot of […]
