I love how casually this guy speaks. Almost like a friend sharing notes :)

@bluerie._.3021 3 года назад

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?

You should seriously be a professor or something. You literally made this so much easier for me to understand and you're the only RU-vidr 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!

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!

@ericvt Год назад

been trying to understand this since i was in university. you explained it more clear than my profs lol

@liminal6823 2 года назад

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.

@n00blamer Год назад

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. :)

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!

@greywolf271 2 года назад

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.

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.

@fenfire3824 3 года назад

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.

@222ableVelo 3 года назад

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.

@0x80O0oOverfl0w Год назад

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.

@radioactium Год назад

if you're initializing the variable *y and setting it to the address of x (&x), why does that same *y call the value at that address and not the address itself when you use it later in the code, since you set it to the address in the beginning? that seems inconsistent to me

@vlogtomejr.1919 3 года назад

I suppose the term "numerals" is likely most appropriate for this context.

"Alright, let's learn how to use pointers!" "Use references instead." "Aight, cool."

@nathanmiller9218 3 года назад

Is it possible or allowed to define an integer pointer as int* y = &x as opposed to int *y = &x? I know c++ ignores spaces in most situations, but does asterisk placement make a difference in that statement?

@gabrielaguilar5237 3 года назад

No, it does not make a difference. Defining a pointer as: int* y = &x; int *y = &x; or int * y = &x; are basically the same thing.

@josephzamora2676 Год назад

Int* just makes more sense

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.

@stevenhong7099 3 года назад

Does the location of * matter when declare the variable? For exmaple, int* y and int *y.

@gpetty599 3 года назад

No it doesn’t. It’s like the & in references. It doesn’t matter where you put it. It can be int * x, int* x, or int *x.

@computerprogrammer7942 3 года назад

@@gpetty599 It’s bad practice just use it normally like int* or you are gonna confuse people that come from other C like languages
