Thanks for one more video, this remember me good all times when I was learning C more than 25 years ago.
saldina thank you so much for this video, your videos are the best
good work
Hope you are doing okay!! Haven't seen you around for a while... Your videos are top notch!! Take care!
So Code Beauty, after explaining the disadvantages of dynamic and static arrays, under what conditions they are useful in programming?
Your way of explaining is so practical and easy to understand. I've learned a lot by watching your lessons everyday. Thank you!
I'm starting over from 0 and remembering everything I learned at the computer science university I did here in Brazil. I was away for a long time and I encouraged myself to move on, you are really amazing, you are helping me a lot.
I watched all your videos about arrays, dynamic arrays and multidimensional dynamic arrays, so I knew this one is going to be great as well. Thanks Saldina
I'm happy that my videos helped you 😊💜
Your C++ videos have been a lifesaver. Thanks for making it easy to learn. Any plans to do a video on runtime analysis/optimization?
I was waiting for this video, love it!
very helpful, i finaly understand when to use arrays (Static) and when to use vectors. thanks saldina
amazing explanation, cleared all my doubts as always
Oh.. Saldina, you have the best channel of programming in this world. The BEST, now I'm a python/JS programmer but I watch your videos just because your explaining is perfect!
Thanks for this!
I want to say thank you. I watched all the episodes, it was an amazing adventure. I started with the basics, then functions, pointers and then data structures. I think I am ready for object-oriented programming lessons. I must admit that this will be new to me, but with your help, I am sure I will be able to understand this concept.
Very new to coding, just finished your ten hour coding video on c++, found the diagrams extremely useful and the explanation, this video was useful to, thank you
Happy to hear that. Diagrams are a great way to learn programming, they help you to visualize code even when you don't understand the commands. 😊
@@CodeBeauty hi mam I have learnt programming languages by watching your videos in channel . yesterday I have given an interview almost I felt got a job but the final question was too unexpected by interviewer. she asked me return two 2d array from function without heap . I said we can create a static array and return to the main .she also asked me to implement the code but I didn't get the correct answer . later interviewer told the prototype of returning 2d array is not correctly written . pls mam I am requesting can you do a video on this topic...
love from India..
Among many other youtubers that I tried to get help in my C++ learning, you are really the best one! Thank you!
this is perfect timing i was just hoping to find a vector video by your great channel
I love this channel. I learn so much.
I applied to CS BSc studies today. Wish me luck! 🤞
Same here bro ,did ur colleges start?
Best of luck bro.
Such a lovely and smart young lady! Pure pleasure to watch your videos and learn with your help. Keep going!
thank you for this content, you made it clear to learn and giving out the pros and cons, a lot of thanks❤❤
Thank you so much Saldina for this amazing tutorial 🥰.I hope you make a video about queue vs stack and their advantages and desadvantegs and which one to use according to the situation.
your methods are so easy to understand unlike many youtube contents ! Please would you make some videos about Datastructures and some advances search algorithms using C++.I'm sure you can explain it perfectly!
*Please Make more videos from STL. And cover all the containers in STL with it's built-in functions.*
*Remaining one's are :- Deque, List in ( sequence Containers ) & Set, Mult-Set, Map, Multi-Map ( Associative Containers ) & Stack, Queue ( Container Adapters ).*
Your videos get better every time❤
hi dear saldina , i am 48 years old and I am beginner , you give me as gift more than gold and diamond, you give me "TIME" and "UNDERSTAND", your tubes reduces time of learning and save it and gains performance of understanding. please continue
Thank you so much for starting stl series ❤ 🥰
not only the appearance, your way of teaching is beautiful. Thanks a lot!
Hi CodeBeauty, Most of the time, I watch UA-cam videos on my TV and there's no way to make comments. I am a Software Engineer for quite some time/years and worked on and off with diff. prog. languages and etc. I have been watching some of yours and you explain the topics very well in a concise and clear manner along with the examples. I am in love with ❤
your videos very useful to me , thank you ,keep going
thank you! Nice work!
I'm subscribed to your UA-cam channel and i have the bell notifications turned on as well. I am very curious if you can give any hints about how soon your next UA-cam video will be out and also can you give any hints about what your next C++ topic is going to be about? You are an awesome teacher, you clearly explain C++ concepts so well i can re-watch your past videos over and over again.
Very useful, thanks!
Nicely explained! ❤️❤️
It'll be better if explain 2D vector as well in this video.
Your video is really helpful for me. Hope you release more videos about STL vector🥰
I am a specialist at Codeforces yet I like to study about STL vector a lot (especially this one).
How to focus on learning to code when there is a beautiful teacher like this🧐
Odlični videi , počeo sam da učim C ++ pre mesec dana pa nisam skroz savladao pointere nadam se da to nije problem i da ću vrememom naučiti . Veliki pozdrav ❤️
Super, javi kako ide 😀
Thank you very much for your beautiful videos. I wish you made a video about graph data structures.
I wish u were into Java too, I love the way u explain concepts into simple and understanding way. Thanks for the videos though, learnt new stuffs😁.
dear, precise and very clear explanation, easy to understand. the way you explaining etc are excellent, the name codebeauty, is like beautiful like you, and its very rare that both your talent of teaching skills and yourself very lovely and beatiful. Please keep posted.
Hey Saldina, I coming from freecodeCamp. Ur OOP course was great and ur explanation was beautiful like u.
welcome and thanks 🥰🥰
Saldina, ur tutorials are bloody amazing; thanks a lot.
However, I really would appreciate it if u dedicate some videos to embedded systems (using Eclipse IDE, STM32 IDE, TI...; if recommended).
Introductory projects; nothing more.
Thanks again for all ur efforts.
very nice! im interested in the usage of c++ 20 modules. would be nice if we see that soon
Hi I'm new to this channel I recently started watching your 10+ C++ Course and I love it so much!! The way your explain everything is perfect for me and it helps me understand a lot. I was wondering what is your accent? It's so pretty but I can't figure it out lol. :)
Hi Saldina. Am glad to let you know that you saved my life through easy to comprehend lectures. Thanks so much Madam. Truly, I tell you that your tutorials can make Ben Carson abandon Medicine and be a Software Engineer. Lol. Anyway, just wanted to know,,,, is it in your will to do tutorials on other languages like Javascript or even some web dev frameworks?? If so, am patiently waiting for the publishing of the first video. You amazingly awesome with how you teach us. Thanks so much. 🙏
Will you please plan for adding sessions about design pattern concepts? Thanks a lot for your effort and time.
Hi, hope u r fine. I was wondering if there is any way that you can transfer the content of a struct vector into a struct through STL algorithm in C++?
Love you much!
I have changed to Dart language. But still watching your videos sometimes.
Thank you. 😉
Thank you very much
so beauty and smart.... what I need... Thanks excellent video
Hello. Wanted to ask, how do you put semicolon at the end of the line automatically? Formatter doesn't do it
Excellent.
thank you 🥰
Thank you 👍
Dear lord! C++ was my favorite programming language in college and now I see that exists an auto data type! I need to learn some new things!
Welcome to my channel, hope you'll enjoy the C++ content :D
@@CodeBeauty Oh! I love your content. I'm Venezuelan and thanks to you I am learning English too 😄
Thank you as always!!!!
You're welcome 🤗🥰
Hi saldina nurak Madam.. can you make videos on DBMS ( database management system)
you are a amazing girl ... each video gives us more knowledge and tips
Thank you. Very helpful. I am also watching all your c++ related, I wanted to share one concern as the viewer, Could you please include interview questions on the topics at the end of each session? It would be much more helpful for someone like me who preparing for an interview. Just a request concern :-)
Thank you
Thanks
Coming from freecodecamp oops lecture your videos are awesome 🙌+ you are looking cute in that outfit ❤
How come you don't have to do std::vector::size_type and then assign that to a variable to get the size of the vector ?
Thanks a lot for good information related to vectors. I have a problem to solve in c++: (Input: 1+ 5 + 3 + 4, Output: 1 + 3 + 4 + 5). The question is : can we solve that with vectors and how? Thanks in advance!
Is it better to use Visual Studio or VScode?
Thanks Saldinah
thanks for all videos i am waiting for you to make an video for consts and especially consts in functions!!!!!!!!!!!!!!!
it is hard to understand i think
Thank you .
Can you teach us about algorithms please. I hope it will be superb for your content and it will help us too.
Hi Saldina, I enjoyed your video on STL Vector. However this is the simple version of Vector values. What about a sorting Vector containing Class pointers or structs. This will need a custom sort function to sort on members of the objects. This may be a idea for an extension of this video, or maybe an 'advanced STL Vector' tutorial? I hope you can do something with this idea. Love your videos. Bye, Ron
Hey saldina i am free code camp. U r amazing 😚
If the size of an array is unknown or changes during program execution, vector may be more appropriate. Vector is easier to use because it provides automatic memory management, and its methods allow for easy addition and removal of elements.
In addition, vector provides many useful functions, such as sorting and searching elements, which greatly facilitate programming in C++.
In summary, the decision of whether to use a dynamic array or a vector depends on the specific case and program requirements.
Hongera wewe ni mwamba👏❤
could you make a video on how to make an API rest with c ++? I am looking for an alternative to Spring
can you do a video on the complete STL course on all topics briefly??
Hello Ma'am You make videos on cpp which are great actually ... PLEASE CAN YOU MAKE A VIDEO ON HOW TO CREATE DB APPLICATION USING VISUAL STUDIO FROM A CONSOLE APPLICATION ...
I completely love your way of explaining 😍 but now i am struggling with learning git and git hub can you please make tutorial for how to use git and git hub please
github
you dropped 👑
❤️
Sista pls can u complete full course of DSA. 🙏Plss huge request from 🇮🇳India.
Ur way of teaching is of another level. 🔥❤❤❤❤🥰
vectors of course are better, emplace_back is one of its power, to avoid calling a constructor to create a temporary object and then move it.
I realize that emplace_back can be implemented in dynamic arrays easily, but productivity is very important.
as well I see no performance improvements in using dynamic arrays over vectors, as compilers already inline all vectors class member functions.
as well vectors are nothing more than a wrap-around a dynamic array and obtaining a raw pointer of any element is possible.
they are contiguous data in memory, which means math operators are applicable to the returned pointer.
you have demonstrated all of that in the video.
I also prefer using std::array over the old style of [ ], it also has no performance overhead, because it is POD struct, with only the same size of the total elements in the array.
what microphone do you use?
I love studying!!!!!!
Maybe you could share a few tips regarding this, beacuse many people study only because they have to 😄😄
Thanks for the useful subject. I wonder why we can't use it(the iterator) by itself for gaining the address of an element of the vector if it is a pointer.
And also why it wasn't defined as a pointer, like: int *it instead of being auto without asterisk.
I appreciate if someone gives their comment on it. thanks.
omg i love vectors
You are beautiful. That doesn’t matter. You are great at what you do. I searched for lessons like this. You were the best. Forget your beauty. It will fade.
Hello codeBeauty, how line space will be taken automatically, it's amezing but how?
Can you please arrange your videos one by one with right order in an playlist
mam plz make video on functions and how call stack works..
it's an i interesting suggestion, thanks 😊
@@CodeBeautyMam Thank you so much😍 for providing great knowledge .You are very kind and humble.
What kind of performance gains do you get by using a dynamic array instead of a vector? Why does everybody seem to think de-allocating your memory is such a big deal and prone to bugs? Remembering to put a 'delete' statement after you're done with your array doesn't seem that hard.
Wow
The value of the fifth element in the vector!
Ma'am please make a video on Python.
Love from India.
Hi ma'am please make a video on "KEYBOARD AUTOMATION" using C++ . Through which i should give an input to another application using C++ program .
Treat Gits!
I bet you have Taddy Dits.
YOU ARE SO PREETY AND BEAUTIFUL AND URS STYLE OF TEACHING IS GORGEOUS
Saldina tysm !👍
17:06 iterator position 1? 🤔
Do a full length, serious video on coding interfaces (such as IDEs). What programming “shells” are out there? Advantages and •••. I say shells in quotes because that is the language we used in 1981. Not too sure what the correct words are today. Maybe look at stone age things like VI. That may give you a sense of where things started.
I’m sure there are more old guys watching that can recommend things from the pre-fortran world. Fortran and Pascal led to C. Maybe BSD is a better starting point - no offense to the Pre-Fortran guys.
In all seriousness, you could do a few minutes on “shells” and teach your generation where they come from.
I want to ask you a question, please tell me sir. Write a program to create a text file called " Student.dat " which includes student's rollno , name and mark entered from the user.
Get lost, troll. She's a woman.
Thanks for good tutorial.By the way,you are beatiful
u also make video on python
😍😉😉 from 'INDIA'
please upload dsa of C
Actually your content is the best butI hope so you make a real system to pratice rather than a seprate examples
