stl library

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, whi

STL is a subset of the latest C ++ standard function library, which occupies about 80% of the entire library. The template that plays a key role in the implementation of STL is filled with almost the entire c ++ standard function library. Here, we need to take a look at what

The standard Template Library, a set of template classes and functions, provides the programmer with an algorithm for storing information in a container that accesses the contents of an iterator that stores information. In simple terms, it is divided into three parts, algorithms, iterators, containers, where the iterator is the bridge between the algorithm and the container, allowing programmers to operate the container through the algorithm, and thes

Algorithms that use the C + + standard library include header files The STL algorithm is used to process one or more iterator intervals, and the first interval is usually expressed as a starting point and an end point, while the other intervals simply provide a starting point, and the end point can be deduced based on the number of elements in the first interval. The caller is required to guarantee the vali

A doubly linked list is a common data structure. It's not complicated, and it's not too difficult if we're going to make it ourselves. But since the STL has provided us with one, it may be used directly. To do so, not only saves time and effort, but also the reusability of code. Header files and template classes To use a doubly linked list provided by STL, you need to include a header file #include This a

There are a lot of STL libraries available for Android, but the Gnustl feature is undoubtedly the most comprehensive. Baidu, found a lot of people on the NDK using STL Library is not comprehensive, often gunstl static over-inking, therefore, I am here to tell the use of Share library.

Using the STL library sort function to sort vectors, the contents of a vector are pointers to objects, not objects.The code is as follows1#include 2#include 3#include 4 5 using namespacestd;6 7 classELM8 {9 Public:Ten intM_isortproof; One A Private: - int__m_ivalue; - Static int__m_icnt; the - Public: - Elm (); - intGetValue (intIX); + voidPrintelm ();

Perhaps you have used C + + as the main programming language to solve TopCoder problems. This means that you have simply used the STL because both the array and the string are passed as STL objects to the function. You may have noticed that many programmers write code much faster and more succinctly than you. Maybe you're not yet. But want to be a C + + program APE, because this programming language is powe

definition is complete, insert the data into the arrayV.resize (3); v[0] = 1;v[1] = 4;v[2] = 3;Allocate three storage spaces, and then assign them to a value. The above embodies the characteristics of an array, but it does not yet reflect the dynamic array. The following describes the dynamic expansion of arrays.V.push_back (2);The meaning of this sentence is to insert 2 of this data into the end of the array. The length of the array is 3, and when the length is insufficient, the vector expands

1.

A significant change in C ++ 11 is that some functions in the boost Library have been formally standardized and integrated into STL. This article will briefly introduce them.Reference Wrapper) When the template function parameter is of the generic type, you cannot export whether to pass the value or to reference it. By default, the value transmission method is used. You can use std: ref to explicitly specif
