STL (Standard Template Library) and Basic Data Structure in C + +

STL or Standard Template Library in C + + is a ready-made toolkit in the C + + language consisting of frequently used data structures and algorithms.

By this article, it contains STL and basic data structures that in C + + of 6 types are Array, Vector, Queue, Priority Queue, Pair and Tuple.

Each type has a different significance, and is used to solve different problems.

- Array: Fixed-size data structures store the same type of data in memory. Access data very quickly through Index, but can't change size later.

- Vector: Dynamic-size automatic modifiable size array, can increase or decrease data as needed, highly flexible, and is the most popular STL.

- Queue: FIFO Data Structure (First-In, First-Out) Data that comes in first to get out first, like a real-life shopping queue.

- Priority Queue: Priority Queue The most valuable (or least as set) information is placed on the front end and is always put out to use first.

- Pair: A structure used for matching 2 data together (with both data not necessarily of the same type). It is commonly used to store $(x, y) $coordinates or key pairs with value (Key-Value).

- Tuple: A structure similar to Pair, but more powerful in that it can bind together 3 or more data (or any number of them) and different types. It allows multiple values to be returned from the function simultaneously.
