I thought of an analogy for when you would use pointers: Say you ask a friend to do something regarding an essay you have on an online cloud (calling a function), but to do so, you would need to send them the essay (the arguments). You can either: 1. Send them a copy of the essay via email/message. This would give them the essay as it was when you sent it, and any changes will not transfer between versions. This means that you and your friend would only be able to see each other's essays if you were to directly communicate with each other. 2. Send them a link to the spot in the cloud where the essay is in the cloud. The link itself wouldn't be the essay, but they would be able to find the essay by following the link and any changes made by either you or your friend will be visible to anyone that looks at the essay. Option 1 would be like directly inputting the variable, while option 2 would be like using a pointer. Is this right?
Good, good, good. The book I was learning from told about assigning and dereferencing with * but never said anything about using *x , for example, by just referring to x. Now I know. Also, this video made me feel mad clever, like one of those beautiful mind guys writing nifty equations on a chalk-board that nobody else can understand.
Nice video man. One thing I had a question about but didn't hear you mention, is the pointer an int because it's a memory address or because it's pointing to an int? In other words, if your original variable was something other than an int would the pointer change or would it still be an int? I was a bit confused on that aspect. Cheers.
This guy just explained pointers the best I've ever heard it explained........... and I'm still confused. lol Whoever was the architect of doing it this way in the beginning needs to be tarred and feathered.
There are no uses for Pointers in programming. Simply use references when passing to void functions instead. Also if you do not free or delete your pointers their address is locked in the memory free space preventing other programs access to that memory space. So if your machine stores many pointers or repeated pointers that use a different address of these locked addresses they will build up and it will crash and this is exactly why Chrome crashes. They can run you out of memory.
int* x seems more readable to me than int *x - it makes it more clear that it's an "int-pointer" ie. its own type, distinct from int. I know there all kinds of arguments about this but I don't care because I'm always right.
You should seriously be a professor or something. You literally made this so much easier for me to understand and you're the only TH-camr I can find that teaches before coding which is why I only watch your videos lol
I don't want to say other lessons bad, it's the best of 5 which I saw about pointers in recommends, and... really understand what it is and how to use it after watching. But, why is here low number of likes, not even 500. Everyone, put likes, this lesson deserves it!
Caleb, you figure out what might be difficult to understand and you explain it very clearly. You are a great teacher, keep up the good work! Thank you very much :)
awesome! in my class they are teaching us about pointers and new, delete, null, which seems like the old and harder way of doing things, but thanks for mentioning it in your video! most ppl skip it because its not used frequently but when we have to follow a curriculum from univ is hard to avoid and find info about those. thank u!
I like that you use a white board, I've had difficulties following other coding teachers on youtube who only use the IDE while talking about these topics. I find the whiteboard much easier to follow possibly because I'm a visual learner. You also do an amazing job dumbing down concepts that makes them easier to understand.
My professor constantly reminds us that he has a doctorate masters wizard of oz Jedi degree in computer science and yet Caleb here, explains pointers way better than his bald a$$. Thank you, Caleb.
You just made pointers click. it's a type of it's own, just like an 'int' or a 'string'. Rather than putting 'int' the pointer variable is * with a prefix of what variable it is your pointing to... The you give it a name and assign it to the variable you're pointing too.
"Only use pointers when you have to!" My professors giving me starter code for an assignment: I'm gonna pretend I didn't see that Me, who hasn't touched C++ all summer: tf does this asterisk do again?
8:27 was the point of no return where i crossed into learning about pointers all thanks to you Caleb! I love your explanation videos! Thank you for making teaching and explaining these concepts!
At the end of the video you started firing them little neurons I got, then said “but let’s not get into the weeds we’ll just stop here” 😭 good video though, I wanna move from Java to c++ and this was one of the first videos I watched, so thanks.
I hope you are making millions off these videos because you are helping millions. If you started a goFundMe and asked all your viewers to donate a dollar we would all do it and you would be rich
I learnt more about pointers after learning C from the K&R textbook and Michael Daconta's C++ Pointers and Dynamic Memory Managements. Kernighan and Ritchie explain pointers very well and Daconta's book is highly recommended for furthering your knowledge.
I was really confused about the meaning of the asterik when using pointers, and how it can be used in a couple different ways. This video really helped clear that up. Thanks!
I heard someone say you needed points to program a game, I had him explain to me what pointers are but I didn’t understand it or why I would need it, thanks for the great video
Oh my god! I luv your explanation of pointers! My professor at school is so confusing so I had to go to youtube to find a better explanation. Your video at explaining pointers is very clear!
Pointers are great for "hacking" other software, if it does not have an api. You can find out the memory addresses and read the data of other stuff and use it in your own software. Pretty sure it is violating some policys in a way, but sometimes it is an unfortunate necessarity. It is basicly the same as using cheat engine. Said differently, you can use a tool like cheat engine to find out memory locations and use this in your programs for whatever you need it.

Nice analogy,well explained.
so... DropBox ?
That's the confusing part with reference
I love how casually this guy speaks. Almost like a friend sharing notes :)
I've been struggling with understanding pointers in my C++ course, but your explanation made so much more sense! Thank you!
Great help in understanding pointers! Thanks Caleb.
Hallelujah for this man. Fighting the good fight
Good job on explaining it. Thank you very much. Rock on!

Thanks!
Thanks for the pointers
You are great teacher!
Great stuff.
Hey Caleb, hope you're doing well my dude
I slapped it!
stunning!!
I love you Caleb!
Thanks 🫡
Good job
You da best!
Superb
So good
8:20 I was gonna do that
OMG! THANKSSS

Hi Bucky , 😂
The most confusing part of C++ along with dynamics arrays.
What's confusing? It's just people don't know how to explain what it does
*doesn’t know the word to describe digits for hexadecimal*
…then says these numbers aren’t significant. How close can you get hahah
that pun almost made me press dislike, never mind the video was amazing
lifesaver, Pearson's textbook is trash
Confusing as crap
bad explanation
disliked ur video because of ur joke!!!!!!!
Goddamn you explained this so wonderfully in 15 mins that my professors couldn't in an entire semester lol
literally very fucking true
Yes
Almost as though a lot of CS professors aren't always sure of what they are teaching....almost lol!
@@humann5682 or just dont care
@@humann5682 wow didn't know this was common until now lmao.
Finally! Big help for me right now during my class. Thanks dude.
int* x seems more readable to me than int *x - it makes it more clear that it's an "int-pointer" ie. its own type, distinct from int. I know there all kinds of arguments about this but I don't care because I'm always right.
I'm with you on this one, all the arguments are blah blah blah multiple variables blah blah.. we're just right it's that simple. :)
You should seriously be a professor or something. You literally made this so much easier for me to understand and you're the only TH-camr I can find that teaches before coding which is why I only watch your videos lol
Holy... My professor could never explain this so smoothly in half a semester. Thank you!

Caleb, you figure out what might be difficult to understand and you explain it very clearly. You are a great teacher, keep up the good work! Thank you very much :)
Agreed!
Certainly the best video on pointers, I wish more people taught concepts like this, rather than just showing a bit of code and syntax
4:09 As if Hexadecimal "numbers" makes sense lol... hex includes letters. I would just say hexadecimal characters...
Well in hex A-F would be numbers not characters. All kinds of confusing 😉
I suppose the term "numerals" is likely most appropriate for this context.
Hey Caleb, thanks for make this content available,I'm feeling less dumb now.
I dont know why, but even though C++ is harder...typing it is so much more satisfying .....atleast for me.
Thanks for the pointers LMAO
He _pointed_ us in the right direction

This guy is so funny. And very well explained a very difficult and confusing subject.
The pointer pun 👌 LOL
been trying to understand this since i was in university. you explained it more clear than my profs lol
Thanks for uploading. Pointers are terrifying for(almost) every student learning C++.
Finally, the video/topic I've been waiting for
@8:27 "c programming... disgusting..." I'll repeat that after you as many times as you want! 🙂 But seriously, I love the way you teach!
Great video, really helped me get a handle on the concept while keeping it interesting. Thanks for the help and keep doing you bro!

thank you for posting. i did not understand and my professor hardly explained it.
int x = 5
int *p = &x (adress of)
x = 5
&x = 0x5ffe94 (some adress in memory)
p = 0x5ffe94
*p = 5
i'm 22 seconds into the video and ive already clicked the like button and subscribed, only from that Pointer joke. amazing
6:02 confusing! It is * not ptr 6:07 confusing! Beginners will think you have to use the variable names X and Y
You explain things really well. Subbed!
watched like 10 videos about pointers. That's the one that made me understand how and why use pointers

9:10 then why not just write int* y = &x and then cout
Why the heck is it always the youtube videos that make sense and not the professors.

"Alright, let's learn how to use pointers!"
"Use references instead."
"Aight, cool."
Thank you!
like given just for the pun at the beginning
1 year after high school i'm finally kind of understanding
thx for helping me learning pointer please continue create more tutorial video!!
Caleb wazzzzup brothaaaaaaa!
You are smart and cute. Haha
Getting a like for the comments you did. LOL :D
Pointer in C: int *p
Pointer in C++: std::unique_ptr p

Where's the second part? Amazing video
pointer are way easier that i thought, nothing compare to recursion
I feel sorry when i didn't laugh 😂😂😂
Just try combination of & and * until it works
