, but also involves a different knowledge point, which is the most important container and algorithm, the other components play the role of matchmaking, so that the algorithm and container can be fused better and more convenient to use. The general relationship between components such as (Pictures from the network):The interaction of the six components: container (container) through the allocator (configurator) to obtain data storage space, algorithm (algorithm) through iterator (iterator) acces

Six major STL components-Allocator (memory allocation, profound things) and six stl SGI has designed a dual-layer configurator. The first-level configurator directly uses malloc () and free (). The second-level configurator uses different policies as needed: when the configuration block exceeds bytes, the first-level provisioner is called as "large enough". When the configuration area is smaller than bytes,

Six major STL components-iterator, six major stl components Iterator:In addition to the subscript method that is common in other languages to access container elements, the C ++ language provides a completely new method-iterator (iterator) to access container elements. The iterator is similar to a reference and points to an element in the container. In another way, containers are generic data structures, wh

In the last project, I thought of using the MFC container class, so I kept the promise to come to a cobarray class. Because my project is used on the server side and has been running for many years, so it didn't take long for me to run, so I found a memory leakage problem. Shit, I almost checked my own section.CodeLater, I found that the cobarray class was used, but it was not released. It was very difficult to see msdn. It was not very good at solving problems such as memory release. So I am lo

Priority queue (forwarding) for STL containers and priority queue for stl containersPriority queue of STL containers Address: http://www.cnblogs.com/summerRQ/articles/2470130.html Priority queue, which was used in the past when I used to brush questions, now I can only remember that its keyword is priority_queue (too hurt ). This data structure is useful in some

See more details: https://zcheng.ren/2016/08/16/STLAllocater/In the implementation of STL, the Space Configurator is the most important one, because the whole STL operation object is placed in the container, how to allocate space for the container so that the container can store the data. At this time we need to configure the Alloc for processing.What does the space Configurator alloc include?The Space Conf

Which will create a temporary one.The copy. In most cases, it is more efficient to pass a constant reference directly, because it avoids the overhead of two of copies. But theRules are not adapted to all situations, su

Detailed usage of set in STL !!!!, How to use set in stl 1. About set C ++ STL has been widely praised and used by many people. It not only provides convenient containers such as vector, string, and list, more importantly, STL encapsulates many complex data structure algorithms and a large number of common data structu

Stl source code analysis: Compiler's predefined location set settings, stl source code At present, my work environment is win, and all demonstrations also use VS or cygwin as the basis. 1. Add the include object to the configuration item and add the pre-defined position set settings. The compiler will add it to the include path, for example, defining a vector (without a suffix) in a folder ), when # include

Class templatesClasses of different types of members can be created based on different parameters.Ii. class template syntax:Template Class Name{Member name;};Iii. class template instantiation1. Syntax: Class Template Name 2. features: the value of the template parameter value table is a type name. The type name can be a basic data type name, a constructed data type name,

Six major STL components-imitation function, six major stl components Functor is to make the use of a class or class template look like a function. The implementation is to overload operator () in a class or class template. This class or class template has the behavior of similar functions. The Imitation function is a smart function, just like the behavior of a smart pointer, which can be seen as a pointer.

In C ++, the STL container type is used as a function and does not use references, which leads to a decrease in program efficiency. stl containers I recently found a problem with algorithm questions: I implement an algorithm recursively, but in the TreeNode * createTree Function(Vector , Int left, int right) TreeNode * createTree (Vector , Int left, int right), The result always times out, I found some

Examples of stl containers and stl containers in c ++ 1. set (set) -- contains sorted data. The values of these data must be unique. That is to say, after the set container is input, the data will be de-duplicated and sorted.S. insert () insert an elementS. begin () s. end () returns the first and last pointers respectively.S. clear () clears the setThe iterator set 2. stringstream (container)-You can s

From the holiday to the present, I haven't touched STL source code for a long time. During the time I went home, I learned Lua. Lua had less learning materials and sent some time. About Lua'sArticleYou can only say that you have time to talk about it. If you are okay, you can play with QT. The article will be added later. I slept for a whole day yesterday and went to the network center in the evening. I sat down in the familiar environment, but

Efficient STL-iterator algorithm, STL-generator Efficient STL-iterator Algorithm Each standard STL container provides four types of iterators: iterator, const_iterator, reverse_iterator, and const_reverse_iterator. At the same time, some forms of insert and erase of the container only accept one of them. There is no

STL container details, stl container details STL containers can be divided into the following categories:I. Sequence containers, including vector, list, deque, string. 2. Associated containers: set, multiset, map, mulmap, hash_set, hash_map, hash_multiset, and hash_multimap 3. Miscellaneous: stack, queue, valarray, and bitset The container class shares some publi
