C++ List (Real examples, Sorting a list, When (not) to use List, Detailed explanation, Step-by-Step)

In this video, we are learning what are STL containers. I will teach you how to use lists in C++ with practical example. We will start with the basics of C++ lists and we will gradually move to more complex practical examples. You will learn how to create a matchmaking system that is used in many popular video games like PUBG, Warzone, Fortnite, and for that, we will use STL lists and iterators. I will also teach you the difference between lists and arrays (vectors). As part of this comparison, we will go through the main pros and cons of lists and vectors.
This video will help you understand the purpose of lists in C++, and in upcoming videos, we will cover the rest of the STL containers.

honestly, this channel is so good that it sums up all the lectures from university in around 30 mins, even more understandable than dry lessons from uni. Thank you

[NYARNAV]

You really helped me a lot, im a self taught because im still at high school.

I already learned pointers, oop, and some basic programming fundamentals from you, when will you make a tutorial for C++ sqlite?

Im not a native English speaker and i really love how you teached, you talk slow but very detailed... Plsss make a sqlite tutorial🙏

[ilyaskhan-jzbq]

Hey Saldina! Your videos have been a game-changer for me in learning programming. Can't wait to see what you have in store for us in your upcoming video!

[kamertonaudiophileplayer]

It sounds as an amazingly good guide in fundamental data structures and a list is a king of them.

[hilgicamala]

i was looking for this literally 2 days ago, i need it for my exams..you are master of the timing Saldina <3

[lulu_barcelonalulu_barcelona]

i thought yout channel is the best thing ever but your course is even better..im finishing my first year at university, you helped me alot <3

[poojaraman]

Really excellent and helpful video😃
I can't understand y is this so underrated😢

[swbqrkc]

this is great, i'm so glad that i found your channel and your practical programming course, greetings from Iceland

[Daniel_florezzz]

Perfect timing I’m legit learning this in my computer science class

[milkamilkica]

i watched your other video about lists and now i don't know which one is better, thank you Saldina :)

[neepunpatil]

From a beginner in C++ to solving 400+ DSA problems on leetcode yes that's all possible because of you 👍🏻👍🏻👍🏻, it wouldn't happen if I haven't learnt C++ from you 😅😅

[christopherrice]

Oh boy😊! Waking up to another C++ coding video! Saldina keeps us on the edge of our seats and she never fails to amaze us✌️🤗!!

[MohammadKarimi-qlnt]

it's good that we have u in programming.
tnx(heart)

[codeoasis]

great video Saldina, i want to praise your Practical Course, i'm learning a lot and i'm very eager to find out what have you prepared for us next

[Hello_world]

thank you sooo much for that wonderful content

[hazarder-njlw]

hey there..i really like your videos, so much that i enrolled your course immediately when you published it and it is great, i would highly encourage everyone to do the same

[melvinsmile]

Perfectly explained. Thank you very much for that 🙂

[robirobi]

great content saldina, i'm enrolled in your course too and im preparing for my finals, wish me luck :D

8:30 I was wondering is there any reason you didn't show the way to iterate over objects in the list with std::for_each or as:
for(auto item : list)
{
}

Syntax?

I feel it would be helpful to try and teach, but I know it can also be difficult as it may introduce a new paradigm in programming, and requires knowledge that these require modern C++ features to be enabled like C++11 and the algorithm header.
