Vector is considered to be a container because it can store various types of objects like a container, in short, a vector is a dynamic array that can hold any type and can add and compress data.

The built-in arrays in C ++ support the container mechanism, but they do not support the abstract semantics of containers. To solve this problem, we need to implement such a class. In standard C ++, container vector is used. The container vector is also a class template.Use the header file # include

Vector is a very useful container in C + +, and here is a detailed description of vector container usage in C + +, as described below
1. Detailed instructions in C + +
Vector is part of the C + + Standard Template Library, a versatile template class and function library that can manipulate a variety of data structures and algorithms.
The arrays in C + + are very pits, are there any data types like the list in Python? It's like vector!. A vector is a collection of objects of the same type, each of which has a corresponding integer index value. As with a string object, the standard library is responsible for managing the memory associated with the storage element. We refer to the vector as a co
, there are some ways to package arraylist,linkedlist, so that they can also be synchronized, but the efficiency may be reduced.Ii. Data growthFrom the internal implementation mechanism, ArrayList and vectors are stored using the array form of OBJEC. When you add elements to both types, if the number of elements exceeds the current length of the inner array, they all need to extend the length of the internal array, vector by default automatically incr
Starting with 5.0 (API level 21), Android is starting to support vector graphics. What is the vector map and the vector map has any advantages and disadvantages is not covered in this article, the specific reference vector map encyclopedia. But here's the advantage:

[1. mathematical significance of features] First we examine a linear change, such as X, the Elliptic Equation in the Y coordinate system can be written as x ^ 2/A ^ 2 + y ^ 2/B ^ 2 = 1. After the coordinate system is rotated about the origin, the elliptic
Vector Vector :Vectors are similar to dynamic arrays, vector and arrays, but once the array capacity is determined to be immutable, the capacity of the vectors is variable. Vectors can only hold any type of object and the capacity is unlimited, the array has no restrictions on the element type but has limited capacity.Application: The

from this beginning I will start to try to translate the Alexey Nefedov "support Vector machines:a simple Tutorial" This textbook, this is our tutor highly recommended SVM textbook, has been feeling a face for a long time , simply open the pit translation, also when it is to deepen understanding, after all, I am also smattering, if the translation of the wrong place also hope that the big boys treatise, welcome suggestions, Welcome to discuss. Well, t
Java.util.vector provides vector classes (vectors) to implement functions similar to dynamic arrays. There is no concept of pointers in the Java language, but if you use pointers correctly and flexibly, you can actually improve the quality of your programs. For example, in c,c++, the so-called "dynamic array" is generally implemented by pointers. To remedy this shortcoming, Java provides a rich library of classes for programmers to use, one of which i

STL container Class C ++ STL embodies the idea of generic programming. It is broadly divided into container, iterator, and algorithm ). A container class can contain a group of objects of the same type or different types. An object of the same type is called a similar container class. An object of different types is called a heterogeneous container class. The container class library contains 10 types of containers, which are classified into three types:
Ordered containers:
2.5 Comparison of vector and raster data structuresEarly in the development of computer-aided cartography and GIS, vector processing technology was originally quoted, and raster data processing began in the middle of the 70 's. A few years ago, these two data structures were hard to be compatible, so they caused a lot of inconvenience to the use of data. In recent years, it has become more and more clear th

The main purpose of the blog is to make notes for themselves to remind.All right, it's officially started.Vector, Chinese is the "vector", how difficult to understand the name, vectors is clearly the concept of geometry, okay? Before the vector or foggy, listen to the students bragging about using vectors to do the storage, really worship a, in fact, this thing is an array of pl
