structure of map, if you are interested, refer to learning STL map and STL set as the data structure basis. Let's look at the implementation of MAP:# Include Don't you think it's easy to use? In addition, the efficiency is very high, 1 million records, up to 20 strings. compare comparison, you can find the record you are looking for; 2 million record items, as long as 21 comparisons are used.The speed will

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

searches is only 1 more times, more than 1/14 of the search time. Once you understand this, you can safely put the elements inside. Finally, for both the map and set winter, they are compared to the efficiency of a C-language packaging library. In many UNIX and Linux platforms, there is a library called ISC, which provides a function similar to the following declaration:voidTree_init (void**tree);void*tree

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

this inheritance relationship, you can use a Forward iterator as an output or input iterator. Similarly, if an algorithm requires a bidireal Al iterator, you can only use this type and random access iterator.Pointer iterator As shown in the following applet, a pointer is also an iterator. This program also shows a major feature of STL-it can be used not only for its own class type, but also for any C or C ++ type. Listing 1, iterdemo. cpp, shows how

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.

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

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.

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 thre

STL Introduction (Standard Template Library) basic components of STL: Containers (Container), iterators (iterator), function objects (functions object) algorithm (algorithms) Iterators is a bridge between the algorithm and the container that uses iterators as parameters to access the container rather than the container directly as the parameter of the algorithm,

Finally, I found the complete Chinese version of objective STL and gave it to everyone.The author explains how to combine STL components to maximize the benefits of library design. This information allows you to develop simple and direct solutions for simple and direct problems, and helps you design elegant methods for more complex problems. I described common

No secret before source code. -- Hou Jie For a classic book, you can get it again every time you read it: Chapter 1: STL Introduction STL design thinking: the coupling of objects is extremely low, the reusability is extremely high, and the library conforms to the Development closed principle. STL value: 1. It brings u

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,
