Vector is a many C ++ STL class. We haven't systematically seen how to use vector before, which makes it difficult to use it. Vector is used to replace directly defined arrays. It can perform subscript out-of-bounds checks and dynamically increase the size. We always recommend that you use vector instead of Type array

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
1. BackgroundIn the field of GIS, pyramid technology has always been a fundamental technology, and the WMTS specification specifically developed a format for slicing requests. With this technique, the front end can quickly display a map or image at a specified level.However, since transduction itself is a picture, the elements of the image that appear to be points of interest simply cannot be interacted with at the front end. Therefore, for the display of ve
C + + linear sequence container The vector is a variable-length array, which is used without the need to declare the upper bound, and as the element increases, the length of the vector increases automatically; the vector class provides an extra way to add and remove elements, which is more efficient than array operations.Header files: #include Namespaces: Using N
Vectors (vector) is a sequential container (Sequence container) that encapsulates a dynamic array of sizes. As with any other type of container, it can hold various types of objects. It is simple to assume that a vector is a dynamic array that can hold any type.
The vector class provides an alternative representation of a built-in array, as in the string class t

I. Overview
Vector is part of the C ++ standard template library. It is a versatile template class and function library that can operate on multiple data structures and algorithms. Vector is a container that can store various types of objects. Simply put, vector is a dynamic array that can store any type and dynamically change the size.
For example:

When using vector, the header file must be included.

Use of the vector of the STL
Getting started with the first part
Vectors can be used instead of arrays in C, or CArray in MFC, from many explanatory documents or online comments, and generally agree that vectors should be used more efficiently and with exceptional security. And vectors are the default containers recommended by STL, unless you know you have special needs, using vectors that do not meet your needs, such as requiring containers to be eff
, 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
