Efficient Use of STLis only a choice of the problem, are STL, may be written out of the efficiency of several times;Familiar with the following terms, efficient use of STL;When the object is large, create a container of pointers instead of objects1) STL works on a copy-based approach, and any elements that need to be placed in the

STL is an important part of the C ++ standard library. It is not only a reusable component library, but also a software framework that contains algorithms and data structures, it is also a good example of C ++ generic programming. Many advanced C ++ technologies are used in STL. This topic describes overload functions. Mainly refer to "C ++ Primer" and "STL sourc

Process-oriented, object-oriented, and generic programming (GP) should be three reusable programming methods. In traditional C ++ languages, generic programming is only embodied in simple template technology. The standard template library (STL) introduced later is the actual embodiment and concrete implementation of generic programming ideas. 1. Problem Introduction A process-oriented method can encapsulate common code segments in a function and reuse

From http://www.vckbase.com/ Author: yy2better Introduction: This article describes how to export STL classes and methods that contain STL classes in DLL. Example source code DLL cannot directly export the generic template (generalized template). Therefore, if you want to export the STL class, the template must be instantiated first (instantiated ). In addition,

The STL container class stores and Manages objects. Although there are no clear restrictions on the inclusion of pointers in STL container classes, STL does not care whether you store objects in containers or pointers. However, considering the original intention of STL, it is obviously out of date to use pointers in th

SOURCE http://blog.csdn.net/huangyimin/article/details/6133650The STL includes containers, iterators, and algorithms:Containers are used to manage some related data types. Each container has its advantages and disadvantages, and different containers reflect the different needs of the program design. The container itself may be implemented by an array or linked list, or each element in the container has a special key value.Iterators are used to travers

Item18 avoid using vector As an STL container, vector In addition, there are not many things related to this topic) One thing cannot be an STL container, because someone will say it is a (, :(). To become an STL container, one thing must satisfy allContainer requirements listed in section 23.1 of the C ++ standard. Among these requirements, there is one: if C is

Each element contains a sort key and a value ). Any element in the sequen

stl 中迭代器可以理解为面向对象版本的广义指针，提供了对容器中的对象的访问方法，可以遍历容器所有元素，也可以访问任意元素。stl 迭代器有以下五种： Input iterators 只读，输入迭代器，支持如：istream Output iterators 只写，输出迭代器，支持如：ostream、inserter Forward iterators 读写，前向迭代器，只能前向移动 Bidirectional iterators 读写，双向迭代器，能够双向移动，支持如: list、set、map Random access iterators 读写，随机迭代器，可以随机访问，支持如：vector、deque、string 从功能上看，输入和输出迭代器并列，然后前向迭代器、双向迭代器和随机迭代器之间的关系就类似于类的继承关系。比如，可以将随机访问迭代器作为双向迭代器或前向迭代器来使用。 举例

STL is easy to understand. However, if you want to know more about the implementation of STL source code, you can design your own template class in the future.First, you should understand and master the design method of the template class, and then recommend the C ++ template metaprogramming and STL source code analysis, which are profound and profound

http://blog.csdn.net/sunshinewave/article/details/80683261. About SetC + + STL has been widely praised, also used by many people, not only to provide such as vector, String, list and other convenient containers, more importantly, STL encapsulates a lot of complex data structure algorithms and a large number of commonly used data structure operations. Vector package Array, list encapsulates the linked list,

iteratorsFor STL data structures and algorithms, you can use five types of iterators. The following is a brief description of these five types:Input Iterators provides read-only access to the data.Output Iterators provides write-only access to data.The Forward iterators provides read and write operations and can forward iterators.The bidirectional iterators provides read and write operations and can be operated forward and backward.The random access

Original: http://cissco.iteye.com/blog/379093To help us understand the principles of allocator.Allocator is one of the most mysterious parts of the C + + language standard library. They are rarely used explicitly, and the standard does not specify when they should be used. Today's allocator is very different from the original STL advice, and there are two other designs in the process-both of which depend on some of the language's features, and are onl

Introduction C ++ STL can be divided into standard containers,AlgorithmAnd function objects, iterators and distributors, using the C ++ StandardProgramLibrary, which can greatly reduce ourCodeTo improve code stability and robustness. Standard container C ++ standard containers are divided into sequence containers and associated containers. For sequence containers, C ++ provides the following basic sequences: Vector supports random access and i

0. Content for personal study notes, for reference only, if there are errors and omissions, please correct me!1. All components in the STL are made up of templates, so their elements can be of any type. The components are:-Container: Manages a collection of objects of a class. Different containers have their own pros and cons.-iterators: Used to traverse on an element of an object cluster (Collection of Objects). This cob can be part of a container/co

For the following code: 　　 my_container.erase(iter); My_container is a container of STL, and ITER is an iterator pointing to an element in the container. If it is not in the for, while loop, There is no problem in deleting elements in this way. If you are performing m_container iteration in for and while, deleting all elements that meet the conditions may cause problems. If m_iner iner is iterated in for and while, deleting all eleme

Written in front of the words: in the Internet to find a lot of do not find the right STL data, helpless can only see English, but the English level is really too rubbing, translation down oneself feel embarrassed, so hang up let everybody correct, hope many criticisms!Introduction to the Standard Template Library (STL)　　The standard Template Library, or STL, is

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 C ++. STLCodeIn a broad sense, there are three types: algorithm (Algorithm), Container (co

For example, I want to record a person name and the corresponding storage, and add at any time, to quickly find and modify:Yeu Bu-The head of Huashan faction, called the Gentleman Sword Zhang Sanfeng-Wudang head, Taijiquan founder Oriental undefeated-first master, sunflower treasure ...This information is not complicated if it is saved, but it is more troubl
