vector scam

In the writing of C + + program will find that STL is a good thing, reduce the amount of code, so that the code reuse rate greatly improved, reduce the burden of the program ape. There is a container, you will find that if you write a list, queue, or an array, you have to take the time to worry about how to maintain, the inside of the pointer Ah, memory enough to use Ah, length problems, there is no possibility of overflow ah and so on a series of problems waiting for us to solve, or more headac

A detailed description of vector usage in C + +Vector: A data structure in C + +, exactly a class. It is equivalent to a dynamic array, and when the programmer is unable to know the size of the array that he needs, it can be used to solve the problem to achieve the maximum space savings.Usage:1. The file contains:First, add #includeAlso must be added using namespace std;2. Variable declaration:2.1 Example:

1. Vector spaces and sub-spaces: Contains all n-dimensional column vectors (the reason for using R: The elements of a column vector are real numbers)Operations that are supported within all vector spaces:Real vector space:8 Rules:The use of more or the definition of vector s

[C ++ Note] 7 Library vector Type, libraryvector List Initializer or Element Count? In a few cases, what initialization means depends upon whether we use curly braces or parentheses to pass the initializer (s ). for example, when we initialize a vector vector When we use parentheses, we are saying that the values we supply are to be used to construct the object.

Introduction: Vector is considered a container because it can store various types of objects like a container. Simply put, vector is a dynamic array that can store any type, data can be added and compressed. To use vector, you must include the following code in your header file: # Include Note: The header file does not contain ". H"

Vector IntroductionVector is the most common container in the STL, which is a sequential container that supports random access. Vector is a continuous allocation of memory, from the point of view of data arrangement, and arrays are very similar, different place is: the array is static allocation space, once the size of the space allocated, it can not be changed, and vec
