Introduction to Programming and Computer Science - Full Course

Absolute pleasure working on this. Thanks again for the opportunity!

This tutorial is a CAREER SAVER. Ive been doing everything all wrong and had 0 clue on what I was doing, but this tutorial is so detailed yet easy enough for a newborn to learn, it taught me everything I needed to know! Thank you so much, freeCodeCamp, Im gonna buy a mug from your store for Christmas.

I can’t thank you enough, this 2hrs video made programming very interesting. This is one of the best introduction to the subject anywhere in the internet Or in any books. It would help if you did the Python introduction

This made for a good refresher for me. One thing I would add from my first programming teacher: "Always comment your code." What he meant was to always have description comments like the pseudocode write-up method, because when you're collaborating or returning to an older project, no one wants to read pages of code, even with a descriptive nomenclature.

After many hours am finally finished the whole video, 12 pages of notes in order to internalize the knowledge but woth it !! thanks to you now i got the basic skills on programming in my road to became a Data Analyst, again THANKS for all your work on this video.

I want to take a moment and thank you guys for making this video, I am extremely grateful. This video was a foundation and I wanted that as I felt lost, thanks.

I am 15 and this is just such a huuuge knowledge treasure to find on the internet.

I just started a coding class and the teacher is assuming all of the class already has basic notions of programming. A few of us don't, including myself. This is exactly what I needed. Thank you so much.

44:17 One question; shouldn't the number in 1,1 position be Ben? I'm confused. If someone could help me understand, I would be really grateful.

Studying a Computer Science degree atm and skimmed through this video, can confirm this is really good and the fact this is free you guys are absolute legends. Good on ya

I thought I was having a stroke when the Loop explanation started… 😅 But now I get it haha great explanation!

Im in 7th grade, and just wanted to learn how to code. This video is a great introduction to coding for me. Keep up the good work

I've just turned 40 and I've come the hard realization that I chose the wrong path in life. A new career in coding could be my salvation. This video might honestly be a lifesaver for me. My goal is to find a job within the next 2 years and if it works, I owe you guys more than words can say. Great job!

I can’t describe how much I love this tutorial. As someone who one day decided to learn programming as a hobby, I was very frustrated how many so called “tutorials” expect you to already know the basics before they even begin (basics is a loose terms, frankly there’s nothing basic about it to me!) I really wanted to give up, I felt stupid every time they’d start writing out a line of code without actually explaining WHY those words were being used in that order, why they were written that way, the difference between a colon and a semicolon or a variable and a float. So to finally find one that explains things and in a way that makes sense… well all I can say is thank you for not making me feel stupid. Maybe I won’t give up after all.

I went to tech school in 2002 and went for graphic design and multimedia. My dream was to create my own video game. I never learned coding though and always wanted to learn the fundamentals. This video I've only watched about 20 minutes and I am completely hooked! I've been using my prior knowledge in my career in Adobe Photoshop and video editing programs but it hasn't helped me get closer to my dream of creating a game. This video has relit the fire I once had and gave me so much motivation to start creating my game. Thank you so much for putting so much work into these videos and sharing this incredible informative course with us. I wish I had you guys as teachers in tech school

I learn best with fun metaphors and the ones used in this video to teach the concepts are fantastic. Thank you for explaining it this way!

I guess we can all agreed that without this video we're pretty much clueless in our programming journey. Thus it makes this video very valuable for us early learners, THANK YOU VERY VERY MUUUCH for making this invaluable *FREE* content

After a week of trying, notes and countless rewinds. I have finished it and it was well worth it. This was amazingly consise (i think), but more importantly, The way these guys descirbed things was just SO good, breaking things down into their simplest elements and slowly building the way up to the bigger branches was awesome. So thank you greatly to all of those that were involved!!

Completed the whole video & what a journey it was. Currently I'm in my web development journey from freecodecamp itself and getting to understand the basics is truly a wholesome development for me in computer science. Totally, a top notch video and thanks for explaining in a such a lucid and easy way.

Really simple and explicit. This is my first time of learning programming and i am really enjoying how you are dishing out the knowledge as simple as possible. Thanks alot Sirs.

People should appreciate the effort of this channel because this channel is sharing knowledge more than we deserve for free and many people still don't know about this. What a SHAMEEE!!

A must watch for all those who are newbies or starters in programming ! Appreciate thier efforts in creating this simple easily digestible bit by bit tutorials 🥰🥰🥰 Thank you guys !

This was so helpful. I am jumping into Web Languages and Interactive Media class this semester and I am so lost. This helped me out a lot and now I know what to do next to eventually understand the class material better. Thank you so much!

Thanks guys! Great video I learned a TON of information!! I’m a 41 year old construction worker. High school dropout. Now I want to learn computer science. This video has inspired me to press on with a humble excitement. Ty guys! Again.

An excellent video, can't believe this is completely free. Really motivated to continue with my web development journey, and cleared up some initial misunderstanding that I had about coding and programming in general. Will direct my friends to watch this in the future for sure!

I'm finishing my bachelor's in CS next month and I'm watching this because you never want to forget the fundamentals, you always come back to this stuff.

Are there any particular songs that help get your creative juices flowing when writing code?

This was a fantastic idea. Well done and thank you all. I've been a novice to experienced user of different systems for years but only recently have I decided to, in honor of all my family and friends who've spent 33 years telling me to do so, "get into computers". While a lot of this video is a refresher for me, the simplified explanations and detailed examples make it unique and very easy to comprehend. Thank you. I could give a big, long, and emotional reason as to why I've decided to make this change in my life but I'll simply say that I'm probably not the only one to has a slightly deep connection to the focus of this video. Thank you guys or gals. Sincerely, Sheddy

I'm 13, and in my country there are no "coding classes" you can take, even in schools. Me and my friends want to be game developers, and this sure is helping us out. Right now I'm searching for an IDE to start(I've tried Visual Studio, too complicated, didn't like it). From a programmer family friend, I've been suggested to learn python first, even though I want to be a web developer in my 16 and 17s ( I think javascript and HTML are best for that), but there's plenty of time to learn. You guys did a splendid and useful video, that's still being watched to this day! Thank you!

you guys did a fantastic job. Im an hr in and im getting more curious as it goes on, its the way you describe the definitions using real life everyday things that make it are clear and logical to me. thank you for your time and effort, I have no idea what exactly what im getting into but I don't mind the time spent im going to the library to get more books !

Nicely done ✅🔥🔥🔥👾👾👾

I'm a 29 year old mom who regrets my career path and need a career change, thank you for providing all this free learning content that I'm consuming like crazy, in September I'm going to do a coding bootcamp after finishing the freecodecamp curriculum and hope that I can one day have a job in software development. If anyone has any tips or bootcamp recommendations I would appreciate it. I'm thinking of doing SheCodes, I can't afford to go back to school for a Bachelors.

I truly wonder how much time it took them to create the PowerPoint and do everything else. Absolutely loved it and helped a lot 😀😀😀😀

So glad that I found this channel!! I have never recommended anything to anyone, but now I will!! Awesome commentary voices and even easier to follow script!! I am even more interested in learning the way of modern technology and computers now than I was twenty minutes ago when I first started the video!!

This is amazing to follow along with Cornell notes. Amazing analogies too, they helped me a lot.

This is great. Well structured lesson. So excited about learning👏

Outstanding video-lessons! Guys, thanks for this treasure! When you know the core ideas, you able to understand the whole process!

Im 20 minutes in and already your clear and succinct explanation is allowing me to soak up the knowledge being taught. Thank you!

Thank you for this amazing content. Many online courses and bootcamps fail to go over the foundations and this is exactly what we needed

Such a highlight for a beginner like me. This was the best place to start before enrolling into a data analytics course. I've been so enlightened. Thank you guys

This is what society needs. Great people, giving great things to help others. A very kind gesture given without pay, you are one of the heroes of modern education. May God bless.

Thanks for this. I recently was offered a c# course, but i lack the fundamentals of programming logic, so this is sure to help me out a lot without spending money. Thank you!

Absolutely brilliant effort. Really loved it.

This channel is amazing. I am very thankful your team made these courses available for everyone.

Excellent introduction before I start my programming course. Thank you immensely.

2 years later and this video is still Gold. I’m wanting to get into programming but I’m scared of failing. I rlly hope if I do get into it, I have a teacher like you. Thanks man💪🏽

I got stuck in the loops lol thank you for such a powerful and knowledgeable course. I will report back here once I become a programmer

An incredible amount of information provided so far. I suspect that each thing learned so far have a huge application.

Finally, I did it, It took me around 6-7 hours to complete it including making notes and it has been very useful and I am fully satisfied. Thanks, Steven and Shawn.

I've struck gold. Started studying a few months ago, and I needed this. Thank you so much

I can say you are one of the best tutor I have met, u take your time to explain, I also watched you tutorial on OOP, it was 🤯. Well done 👍.

Brilliant!! Could have done with this video 20 years ago when I had a go at C++, keep up the good work!!!!!!!

Absolute pleasure working on this . Thanks again for the opportunity!

I just have to say this is such a complex topic made so clear, this is a really excellent work made free, thank you so much!

30:19 When you multiply a string by an integer, . This new string is the original string, repeated X number of times (where X is the value of the integer). So in a way, a string can be both multiplied and added.

You do a very good job explaining brother. One of the best tuts I've came across on yt. Keep up your work. People who don't know how software works can really get done on this.

Absolute pleasure working on this. Thanks again for the opportunity!

I know this has been mentioned a few times, but at 44:15, covering 2D arrays, I believe that position 1,1 would be Ben, not Chris. This is overall a great vid though and sometimes it is very helpful to refer back to the fundamentals in order to clear out any bad-habit/incorrect thought processes in your programming.

Thank you so much for this. I'm about to start my programming journey and our professor wants us to start with C as our general purpose language.

Thanks for this amazing course and your efforts :)

Thanks for trying to teach an old dog new tricks! I started on computers and used punch card, back in 1974, and have always wanted to go back and learn how to understand and write code. (I was an Operating Room Scrub RN for the last twenty one years, worked in the ER, Recovery Room and Hospice prior to that, and never needed my programming/computer skill but I’m retired now and I’m eager to learn)

Amazing material and well explained. Thank you very much. I'm also doing your courses on the website.

I finished this video for 3 days. It was exhausting for sure but totally worth it. Took my notes and I'm ready to jump in the world of Programming. Thank you very much for this!

exactly what i was looking for omg. i'm a 16 yo art student that just wanted to learn how to code as a hobby, so this course was a great introduction before diving into js since i'm done with html/css. thanks so much for creating this invaluable free content!

Thank FCC for sharing the knowledge...more than greatly appreciated for your contributions to the community.

Excelente curso introductorio. Muchísimas gracias. Excellent introductory course. Thank you very much. 👏👏👏

I wish I had this resource 15 years ago when I was struggling through my 1st semester of Computer Science learning Java. I was so lost I totally lost interest in attempting coding, but this makes me want to give learning programming another go.

great video, took about 6 hours with note taking and replaying certain sections, but it finally clicked and i understood it. Thanks for taking your time to make these videos.

Looking into getting a Data Science Degree or something similar. I already have Bachelor's in Neuroscience, but I work with Data for an oncology company and want to learn more about it. This video helps clear up a lot of the basics for me! Thank you

New to the whole thing! Gonna be foing to college for this soon and thank you for the time and knowledge you guys are happy to share. I subscribed and will let me friends know of your channel who are doing the same major as well.

I've been wanting to learn programming for awhile, but had absolutely no idea of what it all entails. This video really helped to give me that, thanks so much! I'm so excited to start my journey into computer software.

Very good, thank you. As a product designer, I should've watched this video years ago. Thank you :)🙏

This is a really good video. I’m in my third year majoring in computer science and this is pretty solid. I wish I watched this before starting college.

As someone interested in learning how to code and getting into tech, I've read that the main differences between coding bootcamp grads and CS grads is the foundation taught in a 4 year curriculum. What are some of the skills that bootcamp grads might miss not going the traditional route? Is it easy to learn those skills afterward when in the job field and to then apply them?

3:15 binary 8:57 certain functions

Thank you very much for breaking it down. Very easy to follow and Understand. EXCELLENT Video. If you want to get into coding, this is a GREAT starting point.

Thank you so much for this amazing video!! It's so easy to follow

Thank you such for creating this video. It was SUPER OVERWHELMING towards the end but extremely interesting. Practice, practice, practice is all it is called for. Thank you for the broken down explanations, much appreciated. 🙏🏾

Thanks so much, coming from a family & friend group of coders and understanding none of it, this was a fantastic introduction to the subject. Great video, thanks!

This was such a great course. Although I know most of it, it was a great refresher and also helped me see the gaps in my knowledge. Thank you for this!

Wow! Thank you very much for doing a cool and helpful video about coding! This video is an amazing guide for starters of coding and programming. I recommend that video for beginners. Have a nice day! :)

I'm speechless, if you can understand it you can make it simple. You guys just made it simple. Thank you

This was really helpful! Thank you all so much. Ngl first time commenting about how something helped me on a yt video: Y'all made me even more excited about go learning to code. Keep up the good work. 💪

19:09 mistake in the code , the correct code would be-> print("game over,",(4+4),"was your final score") Also 19:04 TypeError-> can only concatenate str (not "int") to str

watched it all as a refresher to my first semester of CS and you literally covered about a couple dozen hours of lectures/reading into this short timeframe - amazing!!!!

Wow this was soo good. After self teaching with codecademy, w3school and copying and pasting through a bunch of tutorials to eventually being able to write some of my own stuff with thought of writing clean code... there was still a lot of foundational information gaps. This video helped fill in those gaps. It also does a great job of making it seem less intimidating by calling a Computer dumb multiple times haha. Which helped me understand why the littlest of error can throw the whole thing off. The while communication thing from user to programing language to ide to compiler to binary to computer is helpful. All this time I was doing things like copying youtune tutorials without even Understanding that haha. Oh and the Recrusion part was hell, but it finally clicked.

thanks for this, im working my way through and writing down stuff, im currently at 43:32 and although i know some of the stuff (from using scratch years ago lol) there is a lot that I have learned

That was one of the best experiences I've had, Thanks for this!!!

Hey great video ! Can you please share PDf of the slides you are using, it will be great for revision. ❤️🤘

Thank you for this video, your guys are great teachers!

This video came up on its own after the software engineering video I was watching before ended. I was busy applying to full stack bootcamps when it came on and I understood everything with ease. I wish I knew about this video before my previous Java bootcamp which just went over my head. The teacher was just using jargon most of us were unfamiliar with and we were very confused and lost. By the end of the course we hadn't learnt anything we could actually do anything with.

Very useful information for beginners, thank you!

I've been doing for a while self thought and I read many books and watched many tutorials, but this video was yet the best one. Clear explanation and awesome examples for illustration. Thank you NullPointerException! 🙂

I've spent hours trying to figure out where to start. With absolutely zero experience or knowledge, I've been lost trying to watch videos on where to start. All the "starter" videos seem like they are for people with previous experience. THIS is the video I've been looking for. Thank you! You have my sub.
