A brief introduction to 1.vector Vector, as one of the standard containers provided by STL, is often used and has a very important position, and it is also easy to use. Vector, also known as vectors, can be depicted as an array of lengths that can be dynamically altered, with similar functions and arrays. In fact, the more professional description is that

STLYesC ++Class Library.STLThe containers in are queue containers and associated containers, container adapter congtainer adapters: stack, queue, priority queue), bit_set, and string_package. In the series, I will introduce the list, vector, deque and other queue containers, and association containers such as set, multisets, map, and multimaps. There are a total of seven basic container classes. Queue container ordered container): the queue container

1.Differences between points and Vectors A point is an absolute coordinate in a three-dimensional space. Its value is based on the origin, and a vector is used to indicate the amount of force and speed with direction and size, it is usually represented by a line segment with length and direction. Although they all have three components, if a vector is placed in any position in the coordinate system (transla

Support Vector machine is a class two classification model, but it can also be extended to multi-class classification. Based on the characteristics of space maximization and kernel technique, it can flexibly deal with linear or nonlinear classification problems.The support vector machine is a convex two-time programming problem, and the learning algorithm is the optimization algorithm based on convex two-ti

C ++ getting started -- vector of the standard template library Vector is a very useful container in C ++. Vector is considered a container because it can store various types of objects like a container. Simply put, vector can be of any type (int, double, string, can also be a dynamic array of classes), can add and com

When we write data, we often want the data not to be stored at a single point. such as DB1,DB2 can provide write service at the same time, and all have the full amount of data. The client does not have to worry about data-scrambling, regardless of which DB is written. But in real-world scenario

The vector represents an array container that can change size. Just like an array, the vectors of its elements use contiguous storage locations, which means that you can also access pointers on their elements using offsets that often point to elements, and as efficiently as in arrays. But unlike arrays, their size can be dynamically changed, and their storage containers are automatically processed. Inside the vect
