How to Create a Doubly Linked List C++ ( Part 1 )

This is part one of two. In this tutorial, I demonstrate how to code a doubly linked list.

You succesfully taught me more in 8 minutes than my professor did in a one and half hour lecture

[mohdadyg]

Hi sir,
You don't talk, you don't show BUT you really explain, you really teach!

[ShirtOffLJay]

you saved my life. would have easily failed without this. thanks

[jemmytech]

Oh great. I've been looking for this kinda lecture since last week.

Thank you sir!

[abugslife]

This makes understanding so much easier!!! Thank you so much for doing god's work!!

[armdayeveryday]

Thanks a lot man! My professor put 3 hours into explaining this and no one understood a damn thing.

[artimiss]

you're a life saver, thanks so much!

[marcosaenz]

Its great how you explain everything as you go. 

[plague]

you are an amazing human thank you sir.

[adeelmuzaffar]

Thank you Sir,

you made me learn doubly, very easily.

thank you so much your videos so helpful, I'm so glad to found this channel. I can understand what you explain about, so simple and interesting :) Paul Programming

Your videos are very helpful! Thank you! I'm new to programming and I am learning C++. I have been told that C++ is becoming obsolete with the rising of new languages such as Python. Do you think that's true?

[drusha]

structure must be outside the main function. in your tutorial it looks like you have it in the main and before the main which makes for two sets of identical struct's. this causes all kinds of collisions and compiler errors

Thank you paul for such detail and nice explanation. I am just wondering to the last node where you assign tail->next = NULL, above this line you coded two lines, which i think is not necessary for the last node. i.e. tail->next = n; tail = n;.. since its a last node so that is enough to code only tail->next = NULL. I would be grateful for anyone who help me to clear my confusion. Thank you.

[catalinaboteanu]

what happens if you have more nodes because i imagine we cant copy and paste until infinity:)))) awesome video tho!!

[stricker]

How many nodes does a doubly linked list have to have? Can it be just tail and head? Help please

[flanwithaq]

On line 34 on your code, n->prev = tail, I'm confused upon how that logically works to connects both nodes. Since we're configuring n's prev pointer, shouldn't it be pointing to the head of the list?

[hasanq]

i wish you posted a git hub link or something to source code, nice vid tho. thanks

Can you put more data in the structure than just an int, in case of a linked list, structure holds all kind of data, but all examples I have seen so far illustrate only an int?

[musicalspace]

Can you store string instead of integer?
