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
This article on the introduction of STL vector usage is very detailed, please see below

The purpose of this article is to introduce std::vector, how to properly use their member functions, and so on. The use of conditional functions and
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
Reproduced in: http://blog.csdn.net/longshengguoji/article/details/8507394The vector class, known as the vectors class, implements a dynamic array, an array of objects used to change the number of elements. Like arrays, the vector class also
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
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;
