If yes then exchange the data. Similarly, we perform this checking for all the nodes. Now we can easily modify linked list according to our program requirement and try to use it for some real tasks.
There are a number of things that could be improved, and I hope you find this list of suggestions useful. Don't abuse using namespace std Putting using namespace std at the top of every program is a bad habit that you'd do well to avoid. Don't use system "pause" There are two reasons not to use system "cls" or system "pause".
The first is that it is not portable to other operating systems which you may or may not care about now.
The second is that it's a security hole, which you absolutely must care about. Specifically, if some program is defined and named PAUSE or pause, your program will execute that program instead of what you intend, and that other program could be anything. First, isolate these into a seperate functions pause and then modify your code to call those functions instead of system.
Name things consistently We have node and then List, with an uppercase initial letter. It's usually better to name things consistently so that readers of the code including you! See this answer for why and how it's useful. It's best to only use std:: Avoiding the habit of using std:: The code for this should be refactored.
Understand pointers In several cases the code does something like this: What's probably actually needed in most cases is just a pointer. In general, whenever you are writing a variable or function prototype look for places you can use const.
Prefer modern initializers for constructors The code currently has this constructor: Better would be to input a string and then use std:: Keep private data private Outside the List, there is no need to have a node, so I would recommend that the node definition should be a private definition within List.
Simplify deletion of nodes Here's an alternative method for deleting a node that doesn't leak memory and incorporates the previous suggestion./* Write C++ program to implement the double ended queue ADT using a doubly linked list */ 2 Responses to “C++ program to implement the double ended queue using a double linked list” C++ program to implement stack using Linked List.
In this tutorial we have covered inserting a node at the start / beginning of a linked list and inserting a node at the end of a linked list. We will also write a program in C++ to implement inser Views: K. Table of Content.

In computer science, a linked list is a linear collection of data elements, whose order is not given by their physical placement in memory. Instead, each element points to the next.
It is a data structure consisting of a collection of nodes which together represent a ph-vs.com its most basic form, each node contains: data, and a reference (in other words, a link) to the next node in the. Thats more C rather than C++. You should encapsulate the linked list inside a class.
And the pointer Node *head should be a private member variable inside the class pointing directly on the first Node (The actual way you have to allocate memory for one dummy node pointing on the next element. So you waste memory and the logic is more .
Write a C, C++ code to implement binary search program using recursion. What is Binary Search? Binary Search algorithm is used to search an element in a sorted array.
