The vector class implements a dynamic array. and ArrayList and similar, but the two are different:
The vector is accessed synchronously.
Vectors contain a number of traditional methods that do not belong to the set framework.
Vectors are primarily used in cases where the size of an array is not known beforehand, or if only an array of size can be changed.The

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

Like arrays, the vector class also represents the position of the element with a subscript starting from 0, but the array is different when the vector object
The Vector class provides the ability to implement a growing array, and as more elements are added to it, the array becomes larger. After you delete some elements, the array becomes smaller.

1. What is raster data and what is vector data?In GIS, for the classification of data format, we usually divide it into two types: raster data and vector data. Raster data is a cell that considers space as discrete and is expressed by a two-dimensional array or other data organization. Vector data, on the contrary, regards space as continuous, with features (poin

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

A vector is a class in the Java.util package that implements a function similar to a dynamic array.Vectors and arrays are similar and can hold a set of data (data lists). But the size of the array is fixed, and once specified, it cannot be changed, while the vector provides a function similar to "dynamic array", one of the important differences between vectors and arrays is that the capacity of vectors is v
After learning ArrayList and LinkedList, we went on to study vector. Learning the same way as before, the vector has a general understanding, and then learn its source, and finally through the example to learn to use it.

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
The C + + built-in array supports the container's mechanism, but it does not support the semantics of container abstraction. To solve this problem we implement this class ourselves. in standard C + +, it is implemented with container vectors (vector). A container vector is also a class template.The standard library vector type uses the required header file: #incl
