much more complex relative to the vector's contiguous space, with the benefit of configuring or releasing an element space each time an element is inserted or deleted. Therefore, the list of the use of space is absolutely accurate, not a waste. Also, for element insertion or element removal at any location, the list is always constant time. The list in the STL is a doubly linked list, and it is a circular doubly linked list.3. Deque ContainerDeque is

Effective STL Chinese version (Daquan)WinterIn the case of STL, programmers have three realms, starting with STL, then understanding STL, and finally supplementing STL. Effective STL is a very good book to help you better understa

Hou Jie said: Tracking first-class programs, absorbing nutrients from them, and imitating the programs he wrote are much more valuable than the third-stream programs that he thinks he is trying to write, at least I think so-99.999% of the world's programs are at the bottom of the three streams in front of STL! Mr Hou Jie's comment on STL is too high. He used to be familiar with

Simplified STL (Chinese) Author: winter He said that for STL, programmers have three realms: using STL, understanding STL, and adding STL. Negative STL is a very good book that helps you better understand

STL Learning 1: Theoretical Basis of the standard template library, STL (Standard Template Library) is a collection of software developed by the HP lab. This technology has been around for a long time before it was introduced into C ++. In a broad sense, STL is divided into three types: algorithm (algorithm), container (container), and iterator (iterator). contai

0 Why hash_map Have you used map? Map provides a very common function, that is, the key-value storage and search function. For example, if I want to record a person's name and the corresponding storage, and add it at any time, I need to quickly search for and modify it: Yue Bu Qun-the manager of Huashan school, known as Zhang Sanfeng, the manager of Wudang school, the founder of Taijiquan undefeated the East-the first master, Kwai Hua baodian...It is not complicated to save the information, but

Many Algorithm functions (including algorithm) in STL must provide a parameter called a function object. Why is such a parameter required? First, these algorithms usually perform some operation on many elements in a container (that is, objects that store a bunch of similar elements, such as list and vector, for example, sort sorts the elements in the container, find_if finds the elements that meet certain conditions in the container, and count_if calc

Author: winter IntroductionThis article discusses how to use the standard template library (STL), Class templates, function templates, and other programming techniques to solve practical problems. This article involves STL collections and vectors, function templates, class templates, constant checks, error handling, and STL file I/O. To read this article, you mus

Article 36: Understand the correct implementation of copy_if STL has many interesting aspects, one of which is an algorithm with 11 names including "copy: Copy Copy_backward Replace_copy Reverse_copy Replace_copy_if Unique_copy Remove_copy Rotate_copy Remove_copy_if Partial_sort_copy Unintialized_copy But none of them are copy_if. This means you can replace_copy_if, You Can

The feature of set is that all elements are automatically sorted according to the key value, the set element does not have the real value (value) and the key value (key) as well as the map, the key value of the set is the real value, and the real value is the key value. Set does not allow two elements to have the same key value. The value of a set element cannot be modified by an iterator.The only difference between multiset and set is that Multiset allows key values to be duplicated.We use the

the use of STL map and set is not complicated, but there are some difficult to understand, such as: # Why is the efficiency of the insertion and deletion of map and set higher than the other sequence container? # Why did the previously saved iterator not expire after each insert? # Why don't map and set have a reserve function like a vector to pre-allocate data? # When data elements increase (10000 to 20,000 comparisons), how does the insertion and se
