Data Structures: Crash Course Computer Science #14

Today we’re going to talk about on how we organize the data we use on our devices. You might remember last episode we walked through some sorting algorithms, but skipped over how the information actually got there in the first place! And it is this ability to store and access information in a structured and meaningful way that is crucial to programming. From strings, pointers, and nodes, to heaps, trees, and stacks get ready for an ARRAY of new terminology and concepts.

Just remember, if you are new, that this 10m video is a 1 semester or a few books study compressed, so take it lightly.

[reaper]

the videos always seem like a compressed version of my first two years of studying computer science. though not as thorough as the lectures back then, these videos really hold up and explain everything extremely well. great job!

Data structures was my favorite subject in my CS courses in college! It all just makes so much sense, and thinking about how each piece of data relates to all the others is like a fun puzzle.

I told my friends that I now know how to access a 5 dimension matrix. They are no longer my friends.

I'm trying to get my teacher friends to show this series to their students. I love this. All students should see this in class.

For anyone who may just be starting to learn low level languages, be careful when using "NUL" vs "NULL" because they can mean two different things. "NUL" refers to the NUL character or ASCII zero. "NULL" refers to a null pointer - a reference to a non-existent location in memory.

this is an awesome series. i was honestly expecting it to just barely skim the surface of this topic, but it's actually going in to a fair amount of detail. i love it.

I'm learning to Program now, and surprisingly understood everything. Had to stop and scroll back a few times, but that was a beautifully clear explanation of each concept!

[cholten]

Always great folks but that was pretty much an entire term's class-worth of data structures in 10 mins. It'd be fascinating to know how many people who encountered this for the first time kept up!

As a side-note it's really good how you refer everything back to memory locations. So often these days people are taught to use data structures as basic language building blocks with no idea what's going on "under the hood".

So, object orientation next week? :-)

Dear Carrie Anne and crashcourse, I hope you're seeing this.

You are all amazing. Thanks so much for making these very good quality videos and keeping them for free.

I'm considering supporting you after I'm done with binge watching the entire series. I'll definitely recommend this series to others.

I'm impressed. You're amazing.

I am LOVING THIS SERIES! LOVE YOU CARRIE ANNE AND CRASH COURSE!

[Dodgerific]

I love these videos and feel that I am actually finally understanding computers! thank you

[captainnakou]

I'm a computer engineer and I'm doing some Java stuff for like 5 years, and this video gave me the envy to go back doing some C again, like I did back at school.
And I like that.

[victorcovasan]

right now I just hope this will be a never-ending course

[AyeAyeCaptain]

i am so in love with the narrator.She is so adorable ! <3

[LexYeen]

This series is why I'm getting into arduino programming, and this video just helped me get past a hurdle I encountered on my project. Thanks! =D

[BlueGuitarMusic]

You said in the beginning you weren't gonna go into programming yet I feel like I've learned a ton about the fundamentals of code languages and where programming happens. You tricked me into learning way too much!

[BlueyMcPhluey]

this series is like my hit of crack every week that keeps me going
