Summary of the basic usage of STL container vector and stl container vector According to ACM program design, we use examples to demonstrate vector usage. Methods: push_back (), insert (), erase (), clear (), size (), empty (); Algorithm: reverse (), sort (), accumulate (). 1 # include

Scattered records of STL Learning (constantly updating), and stl learning is constantly updatedI write what I use, so I don't pay too much attention to typographical layout. I will sort it out after I write too much: 1: vector 2: The iterator cannot be set for the priority queue because there is no 3: # Include String str2 (str,); // truncate the str string Array 0 ~ Element 7, which comes with the

STL container, stlArticle from http://blog.csdn.net/zhouyunxuanSeven sequence container types1. vector is a type of representation of arrays. It provides an automatic memory management function to dynamically change the length of a vector object and scale down as elements are added or deleted,It provides Random Access to elements. The time for adding and deleting elements at the end is fixed, but the complexity of inserting and deleting elements in th

rational use of custom assigns. 12th: Do not have unrealistic dependencies on the thread safety of STL containers. To an STL implementation you can only expect: It is safe to read multiple threads. Multiple threads are safe to write to different containers. You can't expect the STL library to free you from manual sy

directly. Partition algorithm, you can use List::sort instead of sort and stable_sort sorting. If you need to get a partial_sort or nth_element sort effect, you must use it indirectly. As described above, there are several ways to choose.In short, remember a word: If you want to save time, do not detours, also do not go the extra road! 4 Summary Discussion technology is like a bottomless pit, which can often be easily extended by a few other technical points. So we need to look at the problem f

1. STL STL (Standard Template Library) is an important part of the C ++ language standard. STL takes the form of template classes and template functionsProgramProvides various data structures andAlgorithmIf programmers can make full use of STLCodeSpace, execution time, and coding efficiency are greatly improved.

east"] = "first master, sunflower Collection ";...// Search ..If (namemap. Find ("Yue Bu group ")! = Namemap. End ()){...}Don't you think it's easy to use? In addition, the efficiency is very high, 1 million records, up to 20 strings. compare comparison, you can find the record you are looking for; 2 million record items, as long as 21 comparisons are used.The speed will never meet the actual needs. If there are 1 million records and I need to search frequently, 20 comparisons will also become

container (For details, refer to the article) 11 * use two methods to access the vector. 1. Vector: At () 2. Vector: operator [] OPERATOR [] is mainly used for compatibility with the C language. It can be operated like a C array. However, at () is our first choice because at () performs a boundary check. 12 compress a bloated vector, which is relatively simple. Use the assign of the vector to allocate the space for creating a new vector based on the actual size of the vector. For example: Vecto

indirect layer of traits that separates algorithms from data structures! This makes the iterator a binder so that STL can work together! 6. Therefore,Iterator_traits must be designed with a special version when the input type is Pointer pointer and pointer to const!Introduction The extract programming technology is used in STL,Brief description of extraction technology

Abstract: This article lists several basic STL map and STL set questions. By answering these questions, we explain the data structure in the STL associated container, finally, we raised the question about the built-in balanced binary tree library functions and map and set selection in Unix/Linux, and analyzed the advan

This article is only a personal learning process in conjunction with the online blog, the collation of STL, is only a brief introduction. Learn notes for individuals only. introduction of STL (excerpt from: Chenguang (morning))STL, the standard Template Library, is a highly efficient C + +

In the previous article, the story about stl_vector is just the beginning. In this article, we will analyze the details in vector. Again, I have not read any books on stl source code analysis. I emphasize that this is to prevent others from misunderstanding that I copied it from other places. The subsequent articles will detail the function implementation in vector.I try my best to make it small, and I can try my best to use my own language and my ow

STL 1. Introduction to STL STL (Standard Template Library) is a collection of software developed by the HP lab. It was developed by Alexander Stepanov, Meng Lee, and David R musser while working at the HP lab. Although it mainly appears in C ++, this technology has existed for a long time before it was introduced into

the use of CL parameters to compile, is still a side dish, will only use the simple Generation command, and will not write a perfect makefile.When I use this set of environment to try to compile STLport project, there is a situation where cl.exe exits directly. So in the end I also used the VS comes with Environment settings batch command: Vcvarsall.bat, sample in vs2012: C:\Program Files (x86) \microsoft Visual Studio 11.0\vc\ Vcvarsall.bat. You can compile the STLport-5.2.1 project by running

Introduction: This article describes the methods of exporting STL classes and classes containing STL in DLLs. Example source code DLLs cannot directly export generic templates (generalized template), so if you are exporting an STL class, the template must be instantiated (instantiated) first. In addition, if the exported STL
