cours itself is free
@@altynaymuratkyzy5432 where?

Technically more like 25h. An hour every day and you should be finished with it in about a month or so.
I watch it at 1.25x speed and I think the guy talks fast enough. Any faster and it would be uncomfortable.
The tuition is tax free revenue, loads of it from gov loans, Harvard also has a 34 billion dollar Tax free trust fund. You paid for this course already.
This is for my homies who had to pay to go to Harvard.
What is?
It’s actually free
@@hohi5870 obviously. But why is it for the people that already went there?

Public school education is free K through 12th grade. Many states offer close to free scholarships for simply having a GPA above 3.0. For example, I’m from Florida and was given a “Bright Futures” scholarship for any in-state university. I went to FSU. Wasn’t smart enough for UF. In my opinion, there’s not enough mentors for the majority of students lives and they remain oblivious to these perks.

i love the energy with which Mr malan is teaching. he definitely is loving teaching in this class.
This professor is a beast, so on point. Truly inspiring
It's 24 hours, but if we take Mr Malan's energy into account, it's much more than that. These lessons are packed. Thank you.
fr, this is a full body workout lol
@@hezowrld😂good one dude
Currently in university in England and a few years in now; I have never seen a lecture at this quality and nor have I ever seen a lecturer so enthusiastic, who loves his job more, loves to share knowledge more but most importantly I’ve never seen a lecturer who explains concepts in a way that is easy for people who have never seen the content in their life. Usually, 98% of lecturers talk as if you already have your masters. His methods of teaching and showing in person analogies is outstanding. The fact this is free is unbelievable. Excellent job, Sir.
Lol English people n Quora go nuts on insulting American professors.
God , in that case I feel sorry for students in England.
I'm not saying that this lecture is bad, it obviously is good, bit think that should be norm specially at uni.
Would have thought British lectures would have been better than us lectures
Well unless OP attended OxBridge, Harvard is a better university than wherever they went, not really surprising that the lecturer is so good given how expensive Harvard is
Perhaps Ivy leagues have more of this kind of lecturers as they are at the top~ which usually means they are passionate and good at what they do. But I hope there would be other lecturers out there like him who makes learning easier and more fun for the student
I love the entry song before every class. It puts me in the mood that something incredible is to come (and it does).
Prof Malan was probably the most charismatic professor I had during my masters at Harvard in '15. I'd also recommend his other course, CS50x - Mobile Development.
CS50 also has Game Dev, Web Dev, and ML/AI courses. They also did a few dozen "Twitch Streams" about a multitude of subjects ranging from Git, CSS, Python, Lua, to ML, and more. All available on YT.
How rich you are to study in Harvard ,!!. I can only dream of studying in Harvard 😖😖😖
@@slimshady6242 you literally just got a course for free
@@Pyae718 but there's a difference between real and virtual
@@slimshady6242 Why would you assume he's rich? Perhaps he's on scholarship or is massively in debt due to student loans. Don't pretend you know someone's life situation based on a single sentence. In any case, even if he is rich, that's got nothing to do with you and he likely worked his butt off to make it into Harvard. There's a lot of rich people in our world and most aren't able to get themselves or their kids into Harvard. Focusing on others is not a road that leads to success.
Holy smokes! So grateful for this generous sharing of knowledge and that I stumbled across it at the beginning of my programming journey. Thank you for posting this for the world potential to grow a little bit regardless of economic status!
Dang, first 15 minutes and I'm being humbled at just how clever this professor is at breaking concepts down.

@@Viresh___pg if you like programming in c than go for c++ else java
I really do not understand what this course has to do with computer science. It is misleading...
I really do not know any of my graduated university colleagues who are actually coding something.
Also, at university, I only had one programming course in the first semester. The rest was pure math and logic.
Every electrical engineer and machine builder has more coding experience after studying than a German computer scientist.
In Germany, it is also not called "Computer Wissenschaftler" (which is German for computer scientist). In Germany, it is called "Informatik," which is an acronym for "Informations Automatisierung," which means "information automation." So the German view of an "Informatiker" is of a person who develops mathematical descriptions for automatic information processing, such as AI, communication protocols, traffic flow on streets, search engines, and much more. It usually has nothing to do with actually coding.
So if you concentrate on coding, you are more like an engineer than a computer scientist. And it's not coding that makes the graduated computer scientist so wealthy; it's their mathematical talent
I have been programming professionally for 8 years - there is a TON in this lecture that I didn't know. Thanks for the video
Video Summary:
This video is a full computer science course taught by Dr. David Malan from Harvard University, covering topics such as algorithmic thinking and problem-solving. It is considered one of the best computer science courses in the world and is highly recommended for those interested in programming. The video provides lectures and additional resources for learning.
- 00:00 Dr. David Malan introduces CS50, Harvard University's introduction to computer science and programming, emphasizing problem-solving and the joy of creating something with programming.
- 02:49:55 The instructor demonstrates how to create a calculator program in VS Code.
- 05:39:46 Inside a computer, there are only 0s and 1s, and it's necessary to include header files for prototypes.
- 08:29:40 The video explains how to sort the left and right halves of an array using merge sort algorithm.
- 11:19:31 The code segment demonstrates how to free memory and copy values from one list to another.
- 14:09:24 The code is treating the inputs as strings instead of numbers, causing concatenation instead of addition.

Watching this while being as a CS student, really tells me why Harvard has such a high reputation in the way they teach things in comparison with other Universities. Thanks for sharing this!
Amazing content, well taught and gives a detailed explanation of the lower levels of computer operation and programming. 11 hours in and I will be finishing it all.
Really thankful to this instructor. I have completed my studies in computer science and then worked in IT industry for 10 yrs still no body explained the concepts like this. Its so simple and direct with great explanation. Learned new things and also recommended his videos to my 12 year old and he too is enjoying his videos.
I graduated over a year ago from university with a stats degree. Going to lectures was boring and not engaging at all, I feel like I learned nothing despite sitting through 100s of hours of lectures. Now, I'm sitting here on my own time choosing to watch this. It feels like I can watch through this entire thing over the course of a few months. Really shows how important it is to have good lecturers for learning
technically a day :> college student here :c
@@infinnite4938 😂
Same here. I feel stats is one of those subjects where teachers are often really terrible at conveying sometimes complex questions and solutions. Our lecturers were so fast paced we were going through 70 slides in just under 2 hours per lecture. Impossible to learn that way. The way I actually learned was through UA-cam. The other problem is that stats can be extremely boring and unintuitive at the best of times. It boggles the mind why more stats programmes aren't making use of all the wonderful visualisation/interactive software available to make it more understandable. Instead we get dusty books and endless texts/formulas/distributions etc. Brown university have a great interactive website for stats called "visualising Theory" that I'd highly recommend
@@northernswedenstories1028 you are exactly right. I got MIS degree and when I had my required stats class I had a fresh professor and we just wen't through material very fast. I barely passed and only because most of the class didn't do well on the test and they lowered the plank for everybody. This experience just turned me away from anything to do with statistics. I didn't learn anything and don't want to learn anything related to that. UA-cam might be the way to reinforce formal education with actual knowledge, projects, and experience.
The fact that you have your degree even with boring lectures proves you otherwise. Not boring lectures are just fluff, in the end, no amount of just listening will get you your grades, you will learn the most when you yourself interact with the matter.
Hands down the best teaching skills I’ve seen in years…

how's going?
I see what you did there 😅
is it and useful? or is it just basics? like is it worth the time>
@@that_one_dude... it depends on you, I'm not the one to judge what is worth your time, watch and you'll see.
No part of me has a fascination with "Computer Science" but I am telling you, THIS GUY knows how to teach, because I was sucked in the entire time, and actually retained most of what I've learned! Absolutely love! The excitement he brings is incredible! Sometimes, that is all we need to get through a more difficult subject, or course.
You have no fascination with computer science but just watched 24 hours of the course?
Beacuase he teaches so well
@@ironbolt7431 I watched because I was exploring Free Courses through the Harvard site! I take courses that are in high demand to make my resume more versatile! I have certificates in subjects I don’t necessarily enjoy but has certainly added value to my resume, & career goals!
In retrospect, Yes! I watched this lecture hall, and enjoyed every second lol!
@@ironbolt7431lmao
1 day worth of Computer Science Lesson, Mad Respect for this Dude.
Haven't made it too far into the course but it definitely makes sense with binary meaning 2 digits consisting of nothing but 0s and 1s. And also getting a good understanding of how other digits are formed such as 3 through 9. It's late and I've got to get some sleep but it seems pretty straight forward to me so far. Thanks so much for this course, it's an honor.😎
From what I've watched so far, this is top-notch content. There's an updated version of the video published in 2023 but this older one actually seems better. (I might change my mind about that later as I progress further into the course. We'll see.)
I discovered this course recently and I am thankful that Harvard gave us free courses like this, for self learners like me. Huge respect and this is great. 🙂
Man this is so good... Wish I started this when people recommended it to me but I was stuck in a different course and didn't want to cut half way through to start a new one. Seriously if you're looking into learning compute science and you're reading this comment, go through this first, hes very good at explaining it to your every day human who has never dabbled in programming.

Keep up dude 👏👏
COME BACK MATE, KEEP THE WORK!!
come back dude
Thank you!
I had a hard time with college, but this helped. I'll be able to code better now. it slowed down my own course for me to actually understand how to program and not just code without purpose.
i recently graduated with my bs in cs and im using this to review for interviews, perfect pacing and explanations!
I'm confused. Is this really the full computer science program??? How is this free? It's not everything you will learn correct?
@@clashofqueen93 its a really good intro, but yeah you can learn everything u need to know on yt
This is how enthusiastic a teacher should be! Thanks for providing so much value for free.

Amazing insight. Thanks for this great learning opportunity
I love how enthusiastic and interactive he is!
Thank you very much for combining it into a single lecture. It reduces a lot of hassle.
I appreciate this man. His ability to convey these difficult and hard to understand topics is nothing short of incredible. What a great teacher.
@@dumplingsuwu6691definitely ❤️
5:03:03 is where the actual part on arrays begins. Or for that matter, where people who did any programming in middle school would typically like to get into this course.
My professor surprised us by having an interview style final exam for C. I solved every question and got out early thanks to CS50! What a class!
my man, harvard's cs50 is the best course available online for free, which will definitely build the basic structure into your programming world! cheers for making this into a single video!!!!!
Great teachers! Thanks for the mind blowing lessons ❤
Very grateful for this course! Helped me a lot in my journey to learn development.
This is a truly priceless video and I can't express my gratitude enough for making this available to the general public!
I completed a version of this a couple of years ago. Awesome course. I'd never programmed before in my life and then started working through the algorithms and data structures in c book! This is where my obsession started!
This guy teaches with so much passion! Even though I know most of the concepts from coding in Python, I just can't stop listening to him
thank u for this
I'm in 12th grade, and for a long time, I wanted to go to CS, but now, that it's getting closer, I'm hesitant. This guy makes me fall in love with CS every time I continue watching this video. Thank you.
10 thousand dollar computer science course is now free..
Salute to free code camp 💯💐
Is it really 'worth' that though
CS50 has always been free lmao.. all they did was compile it into one video. Great work anyway.
@@illegalsmirf It surely is.
Free code camp is doing great yeah but this course was already free before they put it on their channel
CS50 was always free bruv
title drew me in saw the whole 1st lecture gonna watch one a day, Dr is seriously a GOAT
It is a new era of endless possibilities for technology and engineering and everyone who wants to know about these important areas of human knowledge.
Im sure there are people like me who were motivated to take the course, but kept it on the side for a while. This professor is SO engaging! These are the type of people that help you learn and grow.
He's not my cup of tea. His course sounds like a Ted Talk.
Thank you, FreeCodeCamp, for not only providing this courses accessible for everyone, but also for combining it in very good structure. Also big appreciation for Harvard CS50 for allowing rest of us chance to access these kind of resources.
A huge respect for you sir🙏🙏
thats crazy, such an amazing proffesor, this is harvard for you.
This is a great course and I am very thankful for all the people who put an effort on this course.
free code camp you guys have put together some of the top names in the computer industry in all fields and brought it to us free of charge you guys are amazing to say the least your my #1 place to go to learn computer "stuff" no matter the subject, a huge thank you.
Professor Malan is so captivating it took me three hours to notice that the front few rows are puppets. Great content, amazing presentation.
Thank you for the video :) will definitely check out more on your channel
I have been a professional programmer for over 11 years now and have worked in a bunch of programming languages, including Python, but I love these lectures, you will always find something new and interesting.
3:30:46 Diferencia entre While loop y For loop 3:51:20 Do while loop 4:36:00 Preprocessing, Compiling, assembling and linking.
This course was great. It fill in missing parts I've needed to find to understand programing Thank you Rob153
I love when the lecturers show passion and excitement for what they teach makes me wish high school teachers showed this type of enthusiasm all my teachers were so boring give or take a few 😂😂
This is priceless! Great appreciation to Harvard University for publishing this course. Dr. Malan is absolutely amazing, his teaching techniques are outstanding.
Oh My Goodness!! This is fabulous! It is so clear. I have never gotten such a succinct and enlightening lecture on binary and general concepts in computer science before this was revealed to me. This is quality content, thank you so much for sharing this!
Really shows how important it is to have good subtitles for learning. Whoever made the lecturers deserves love and support.
"Whoever made the subtitles deserves love and support. Really shows how important it is to have good lecturers for learning." these two phrases are repeated in this comments ection.. why?? it interests me more than the actual 24 hour harvard lecture which is insane...
@@bron2452 because putting subtitles in a video over 24 hours long would take weeks to do. also since people who are watching this most likely ARENT in harvard, they appreciate and can see how much more advanced and better the lectururururues are
24 hours of solid knowledge. This guy is extremely passionate about. we should all pay him $100 instead of paying useless university for four years.
I was confused about where I should start this course and how. Now i have a whole course combined in a video. great efforts freeCodeCamp and thanks to Harvard for providing this precious course for free.
