Insert implementation in Vector Preface The project team should implement an algorithm library that involves the implementation of one-dimensional arrays similar to vector. Here, we will learn and understand vector in STL. If you have any questions, please let me know. Thank you.1. How to implement vector If you have an interview question, how can we use the dat

Houtie teacher in the "STL Source Analysis" said: Understand traits programming technology, just like to get "sesame open" mantra, from this to a glimpse of the mysteries of STL source. The importance of such a word is self-evident.The iterator has been introduced before, knowing that different data structures have their own specific iterators, different iterators also have different characteristics, becaus

STL decomposition is based on loess, the local weighted regression scatter smoothing method, which was 1990 by the University of Michigan's R. B. Professor Cleveland and W of Att Bell Laboratory. S. Cleveland a method of decomposing time series. The STL decomposition breaks down the time series into seasonal items, trend items and residues. In order to study this method, I spent a day poring over this paper

STL contains methods used to iterate elements in containers-iteration methods, including for_each, transform, copy, find, remove 1. Usage: // Template function, print element 2. Details How to Implement for_each? Below is the source code of STL (excluding some diagnostic code) // Template function for_each We can see that every element in the iteration container is used as a parameter to call the third p

Template is a good thing. Classic STL. powerful boost. Dynamic Link is also a good thing. It is called DLL in windows and so (Share Object) in Unix. It can save a lot of trouble for software re-release. However, when a template encounters a dynamic link, it is often a nightmare.Now let's talk about some of the problems I have encountered. The problems are mainly focused on memory allocation.1>For STL, it is

Anti-DDoS program module indirectly transmits STL instance objects through struct We often pass parameters to functions through struct. In principle, the struct should not contain non-pod members. [Reference]========================================================== ==========================================Pod, short for plain old data, a common old data structure (POD) is a data structure. It is used only as the field value of passive favorites, and

STL provides many generic containers, such as vector, list, and map. When using these containers, programmers only need to worry about when to plug objects into the container, instead of how to manage the memory and how much memory is needed. These STL containers greatly facilitate the compilation of C ++ programs. For example, you can use the following statement to create a vector, which is actually an on-

Clause 38: design the imitation function class for value transfer Neither C ++ nor C ++ allows you to pass functions as parameters to other functions. Instead, you must passPointerTo the function. For example, here is a declaration of the standard library function qsort: void qsort(void *base, size_t nmemb, size_t size, int (*cmpfcn)(const void*, const void*)); Cla46 explains why the sort algorithm is generally a better choice than the qsort function, but it is not a problem here. The problem

Finally, I have the opportunity to have the motivation to view jjhou's STL source code parsing. It is expected that the entire book will be read in the fast-reading mode. The underlying mechanisms of map and set are RB-Tree (red-black Tree), and insertion and search are O (lgN) complexity. Map and set have been heard before, but they are never used, because they do not know what is behind them. I read this book to learn about it. Finally, I have the

The examples are rich and

STL, Standard Template Library, is the implementation of C + + for generic programming ideas, which was first developed by HP Labs. This technology has existed for a long time before being introduced to C + +. Later STL became part of the Ansi/iso C + + standard. Each C + + vendor also has its own template library, which may be highly efficient, but portability is not necessarily good.In the C + + standard,

Description: I think to read the source code of allocator part of STL, and draw its thought, at least the following knowledge you want to understand: operator new and operator delete, handler function and a bit of template knowledge. Otherwise, you may not be able to see the following, add some knowledge to learn STL source is better.The following is a combination of the key source code Analysis C++

0 Preface: STL, why do you have to master For programmers, data structures are a compulsory subject. From the search to the sort, from the list to the two fork tree, almost all algorithms and principles need to understand, can not understand also to memorize. Fortunately, these theories have been more mature, the algorithm is also basically fixed, do not need to spend your mind to consider the principle of its algorithm, and no longer to verify its a

I 've been so busy recently, but I still want to write something of my own. I don't know what to write. Finally, I decided to try to implement several collections commonly used in STL by myself, to deepen my understanding of STL, and to see if I have the ability to implement it. The implementation goal is: 1 to be compatible with STL; 2 to maximize the implementa
