Part 1th Vector IntroductionVectors are vector queues, which are classes added by the JDK1.0 version. Inherits from Abstractlist, implements the list, randomaccess, cloneable these interfaces.Vector inherits the Abstractlist and realizes the list;
vector Container
Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to
When using STL containers (such as map, list, vector, etc.), whether to put an object or an object pointer, that is, vector or vector, where the vector can be replaced by other containers, int can be replaced with other basic types, or a custom data
this time we go on to look at the Java data structure vectors (vector) & Stack (stack). The first is the vector, vectors (vector) classes are very similar to the traditional array, but the size of the vector can be changed dynamically according to
Summary of several situations of vector vectors in c ++ (vector pointer and pointer vector)
1. Standard Library vector type
Vector is a set of objects of the same type. Each object has a corresponding integer index value. The standard library will
Standard Library Vector type
Use the required header file:
# Include
Vector: Vector is a class template. It is not a data type. Vector is a data type.
I. Definition and initialization
Vector v1; // The default constructor v1 is empty.
Vector
Document directory
Basic Requirements
Create a vector instance
Preset vector Length
Create a vector with dynamically Adjustable Length
Add a value to a vector object
Use Vector Programming
OneArray)It is like a container that organizes a set
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.
1, briefly describe the basic operation of Vector, its size,capacity (), Clear,reverse,reserve,
Push_back, etc...
2, say, is the vector storage characteristics, whether sequential storage or as a list, if it is sequential storage, then how to
