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

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

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

Thanks to the curiosity of vectors in the STL for the "=" (Assignment operator) support for custom data types, a simple test code was tested.It turns out that vectors support good for assignment budgeting, but for vector arrays of dynamically allocated classes,Bloggers think it's important to override the destructor with the copy constructor and the operator overload "=" operator (this is a software rule, s

In the past, I have read many articles about the top ten essential tools for developing common professional software such as. NET and. Net programmers. Today, I don't want to introduce these professional software. I want to introduce some auxiliary software that is often used during development to help us complete better development. I recommend commonly used a

SGI-- Silicon Graphics [Computer System] Inc. Silicon graph [Computer System] Company. STL-- Standard Template Library: Standard Template Library. Container Concept The STL container is to implement the most commonly used data structures. A container is a collection of specific types of objects. According to the characteristics of data arrangement in containers, containers can be divided into two types: s

In the C ++ language, there are some elements such as arrays, strings, streams, and bitsets that are not part of the standard STL, but are related to STL to some extent. The following is a brief introduction. Array as STL container We know that "dumb" pointers can be good as iterators because they support the required operators. This is not a trivial matter.

STL Source code Analysis-iterator and traits programming methodThe central idea of STL is to separate the algorithms from the containers, design them independently, and finally glue them together, and the generics of the algorithms and containers are not very difficult, C + + class templates and function templates can achieve the goal, but sticking together is the thing of the iterator.So the iterator is to

I have read the source code of the STL space configurator and summarized it as follows:1. STL space configurator: It mainly consists of three file implementations. stl_construct.h defines the global functions construct () and destroy (), which are responsible for Object Construction and Analysis. The stl_alloc.h file defines level 1 and level 2 provisors. The provisioner name is alloc. stl_uninitialized.h d

STL Practice Guide Practical Guide to STLAuthor: Jeff boganTranslation: Zhou Xiang (Part 2) Cursor (iterator) I have said that a cursor is a pointer, but not just a pointer. A cursor is similar to a pointer, and its function is similar to a pointer. However, a cursor returns a value from the center of the container by reloading the "*" and "->" of a dollar. It is not a good idea to store these values in the container, because these values will become

To learn STL, it is necessary to use the adapter and some common algorithms. They are all important components of the STL.Adapter In the STL, adapters can be fitted with some containers. For example, the stack and queue are deque by a double-ended queue. In fact, the adapter is also a design pattern , which is to convert the interface of a class into another interface that the user wants. Simply put:

0 Why do I need hash_mapDid you use map? Map provides a very common feature, which is to provide key-value storage and lookup capabilities. 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

Introduction People often say, do not rebuild from the wheel, to stand on the shoulders of giants. In the face of these STL components that play the role of the wheel, is it necessary to delve into the design principles or implementation details? The answer varies from person to person. From an application perspective, you do not need to explore the implementation details (however, to a considerable extent, understand the underlying implementation of
