Vector Common Methods
assign () assigning values to elements in vectors
void assign (Input_iterator start, Input_iterator end); //void assign (Size_type num, const type VAL);
Reserve () sets the vector smallest element to hold the quantity function to reserve a space for at least a size element for the current vector. (The actual space may be greater than size)

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
I. Definition and initializationVector Vector
Use of vector in C ++
Vector is the most common container in STL. It is an ordered container that supports random access. Simply put, vector is a dynamic array that can store any type of data, but the array is a static allocation space. Once the space is allocated, the size cannot be changed, but the vector is dynamica
Use of Vector
The underlying Array Structure of the vector class, which contains components that can be accessed using integer indexes. However, the vector size can be increased or reduced as needed to meet the needs of adding or removing items after the vector is created. Therefore, you do not need to consider whether
1) Quantity: Also called scalar, pure quantity, only the size has no direction, can use a numerical value to determine;2) Vector: Also known as vector, describing this kind of quantity not only needs the size, but also needs to express its direction;3) directed segment: a segment with a certain length and a definite direction;4) geometric vector: short
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 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.

A vector class is called a Vector class. It implements a dynamic array and is used as an array of objects with variable element quantity. Like an array, the vector class uses subscript

Vector usage in JAVAJava. util. Vector provides a Vector class to implement functions similar to dynamic arrays. There is no pointer concept in the Java language, but correct and flexible use of pointers can indeed greatly improve the quality of the program, for example, the so-called "dynamic array" in C and C ++ is generally implemented by pointers.
