What is Queue in C++ data structures and algorithm?

Queue in C++ Data Structures     

Definition: " The item that is inserted at first in the Queue is retrieved at the first from the QueueQueue works on the Principle of FIFO."

Description

In this pdf/post of Operations On Queue in C++ Data structures and algorithm you will learn about how to Push and retrieve the data from Queue etc.

Note: You will learn about Push function, Pop function, Deque and many more, so keep connection with us for latest articles and posts.

Data Structures

Data structures are used to store and organize information. A data structure is a conceptual organization of data in a computer so that it can be used efficiently. Data structures provide a way to manage large amounts of data effectively.

The six major types of data structures are:

  1. lists
  2. stacks
  3. queues
  4. trees
  5. heaps
  6. graphs

Why Data Structures?

Main memory stores data more quickly than disks or other storage media, because it can be accessed more quickly than disks. It's vital to understand how the operating system retrieves data from memory without using the hard disk. A Data Structure is usually used to organize your data.

Types Of Data Structures

All data structures are divided into two categories:
  • Linear: Linear data structures store information in sequential order. A linked list is an example of a nonlinear data structure. Linked lists are better for insertion and deletion.
  • Nonlinear: nonlinear data structures do not. While an array is an example of a linear one. Arrays are faster for random access. 

The efficiency of data access and update operations are central to the performance of many applications. For example, if an application needs to read or modify only one specific element of a large collection, then accessing that element directly would be more efficient than reading or modifying all elements sequentially. 

There are two types of structure:

  • Collection Structure
  • Linked Structure
Data structures include the fundamental components of the digital world: bits, bytes, numbers, characters, strings, records, files, and objects.
