Many thanks from Russia.
is it just me or is C looks like the linux terminal in kali?
42:24 on what?
University kids learning coding scratch!? Man you are so lucky in 2024!?
세계 최고 교수중 한명,
i should have watched this before code in c.
why create a library that abstracts away actual c code? what's the point in even teaching c like that? Makes this whole lecture pointless imo
I'm not even born yet, and I'm already learning CS50. See you guys in Lecture 2. 💀
Bro anyone told me on which timestamp he download compilar for C language pls tell mee
53:08
28:40 ngl i did that mistake LOL
2:11:49
Thank you sir. Superb lecture.
CS50 has changed my life in 2020, I took this course and introduction to AI, then I went to do my master's. Today I'm a regional lead for data & AI. Big thanks to this course, couldn't have done it without it.
i am not ashamed to say that i was one of the non-zero number of students that put "<studio.h>" and could not figure out why their code wasn't working.
I am learning it at age 17 and I very appreciate this is for making it free I can say this is best of best
can anyone tell me if i should make notes ?

Man, Charlie Sheen got real smart

The Boeing was recording every hundreth of a second. Putting this out there in the hopes that no one else spends half an hour wondering why their code gave 2485 instead of 248.5 🙂
☕☕☕🗿🕑🤟
I've watched old CS50 and was enrolled at the age of 16 because I was a competitive programmer, now I am here again with David and he is really a good teacher IMO, his communication skills are impressive.
wow!
42:46
Day 2 He’s right most of this stuff is going over my head. I’ll just push through learn what I can and watch it again later
I'm learning this at 1000011

Nobody cares what age you start at, boomers.
22 yo MtF here. Trying to learn an actual skill and do something with my life. Never did much programming when I was a kid but Mr Teacher Man explains everything so well even a dumbass like me can understand. Thank you.
2026 first step in coding
David, you need a good diet and stop eating bullshit;
Thank you for the excellent lecture <3
Is C++ gonna be the same as C?

You are very nice. You have left all teachers behind with your engaging way of teaching.

i didnt think i'd ever be capable of doing anything like this, i have no experience with computers outside of being passionate for video games and knowing my way around navigating them…..
today after a day of work i made a very small text adventure game. its made with a few choices, lots of print text and it asks and stores multiple different questions like age, name…etc. I'm doing my absolute best to be humble and realize i still know nothing and continue my journey, i feel very ignorant but doing my best to tell myself i can do this, and doing my best to celebrate the small wins. thanks david.
