Standard Template Library (STL)

1. Standard Template Library (STL): is to provide a common template, this part of the code is high-quality code, improve the programmer's development efficiency

2.vector vectors: Essentially, the encapsulation of an array, characterized by the completion of reading in constant time, more complex inserts, and traversal through iterators

Several ways to initialize vector vectors:

• Vector<t> V1:vector Save the object of type T. Default Construction V1 is empty
• Vector<t> v2 (v1): V2 is a copy of V1
• Vector<t> v3 (n,i): contains an element with n values of I
• Vector<t> v4 (N): V4 contains n replicas with value initialization elements

Several ways to rub vector vectors:

• Push_back (): End insert
• Pop_back (): End Delete
• at (int i): Take the value on position I
• Begin ()
• End ()
• Front (): The value of the header
• Back (): The value to take the tail

3.list Linked list: The feature is that the insertion is relatively simple;

4.map mapping: Stored entries are key-value pairs, and values are found by key
