When using a std::list The list in the STL is a two-way linked list, which can be inserted efficiently to delete elements. The list does not support random access. So there is no at (POS) and operator[]. The list object List1, List2 has element List1 (1,2,3), List2 (4,5,6) respectively. list Construction, deconstruction List ### Other ### C.size ()///Returns the number of elements in the container c.swap (C2)///convert C2 an

List is implemented by bidirectional linked list, the following mainly introduces some operation of STL list. Description: For examples and function declarations not given, see http://www.cplusplus.com/reference/ Implementation: Bits/stl_list.h, BITS_STL/LIST.TCC (libstdc++ or include/c++) 1. Constructor, assign (), size (), max_size (), resize () 1. Constructor function Explicit list (const allocator_type alloc = Allocator_type ()); Explicit list

If we implement a linked list by ourselves, we will write a lot of code, including the implementation of creation, deletion, insert, and so on. But if we use STL, then the template Library provides us with a two-way list of linked lists, so that we can easily implement the linked list operation. To use list, first introduce the header file #include (1) Create List ListThere are several ways to create a list. (2) push_back (), tail insertion

In the data structure there is also a very common queue called the two-terminal queue, we in the last blog, "C + + STL learning--queue" in the queue is the most standard queue, only at the end of the insertion of data, the head to delete data. And today we talked about the deque can be inserted at both ends of the insertion and deletion, can be said to use more flexible. Sample code uploaded to Https://github.com/chenyufeng1991/STL_deque.

");// (SUBSTR): Fetch substring substr String stringsubstr = "Chenyufeng"; 3 characters starting with index 4 cout Find: Finding a character Find string stringfind = "Chenyufeng"; Stringfind.find (' n '); cout The default find function is the subscript index that returns the first occurrence of a character. Find_first_of and find_last_of are respectively the first and last occurrences of a character's index. The string processing functions in these 15 C +

Currently, vectors and maps are the most commonly used two containers in the STL, and when using vectors or maps, they are found in the container as needed and then removed, summarizing the correct results in the actual test. Find: Map Lookup uses the Find function. map iter = Mapintstring.find (1); if (iter! = Mapintstring.end ()) { Todo: } There is no find function in the vector and can only be searched by traversal. Vector for (UINT i

Review the "STL Source Analysis", first of several simple algorithms to achieve their own. Parameter does not use an iterator and uses an integer array directly.#include

value_type* data () noexcept;const value_type* data () const noexcept;returns a pointer to the location of the vector element stored directly in memory. Because the elements inside the vector are stored sequentially, the pointer can access all the elements in the array by an offset.ParametersNoneReturn ValueReturns a pointer to the memory where the first element of the array resides.——————————————————————————————————————————————————————————————————Summary of the bad place please a lot of

Sequencing is always the most commonly used algorithm in data structure, and the algorithm of STL is very rich, and how to use it effectively is worth discussing. I did not find the translation of clause 31 on the Internet, so I translated it myself. --Winter How do I sort? Let me count there are several ways. Once the programmer needs to sort the container elements, the sort algorithm will immediately appear in his mind (some programmers may think

See an article on your Web site: "Insert different types of objects in an STL list (Lists)." I feel that the answer has not pointed out the nature of the problem, so I put forward my point of view, I beg to correct. I think that the cause of the error is the pointer transformation process, the program did not point out the original prototype of the pointer, or, because did not find the correct subclass function address to invoke the error, my original

ZC: Here in the video there is a debugging tips, vs08/vs2010 start, the console program will automatically exit (unlike VC6), then you can set a breakpoint on the last sentence of the function exit, and then view the information printed by the console.ZC: This tells me that the good thing about using string is that the index is out of bounds when the string is manipulated (such as copy/delete operations)"01:05", the main points of this lecture are as follows:One, what things

Previously did not pay attention to the sorting algorithm, because there are very few application scenarios, the recent interview process found that the sorting algorithm is often asked, sometimes in some written or interview topics need to use the sorting algorithm to solve the problem, if each of their own handwritten sort, then it is quite time-consuming, And I don't necessarily write out the wrong sort algorithm in a short time, this time STL prov

However, for the person who writes the template, this method is not flexible, especially when the template parameter is a pointer, if you want to instantiate a parameter different from the type, it becomes impossible! Sometimes, it is impossible to disable the same instantiation! So it appears, partial specialization! At the same time, when using the void * pointer, you ca

Note: memory management is always the red-light area of the C/C ++ program. There are two focuses on memory management. One is the correct use of memory. For example, new and delete in C ++ should appear in pairs and use raiI to manage memory resources, auto_ptr and other aspects, many C/C ++ books use the introduction of skills. The other is the implementation of memory management, such as the slab distributor of the Linux kernel, Allocator implementation in
