Golang Tutorial #19 - Pointers & Derefrence Operator (& and *)

[@ajlee1216]

This has to be one of the best explanations on this confusing Go topic! I certainly walked away with a much fuller understanding. Thanks Tim!

[@autodidactgarage]

Seriously, I did C++ coding for years, somehow never managed to understand what pointers were or how they worked. Recently started to learn Go and this stressed me out all over. All the videos I watched were just as confusing. After watching Tim's video, it completely clicked and now makes perfect sense.

[@TheDavBag]

I'm not an English native speaker, my first language is Russian, but you dude explained this concept to me better than Russian speakers do. Thank you so much!

[@PaullUniverse]

я тоже русский и смотрю английских ютуберов которые объясняют темы в языках программирования. Как по мне, у англичан лучше получается давать объяснение таким важным и интересным темам. Я считаю, что это невероятно круто. Спасибо ТИМ!

[@Bingminglin]

best video ever explain crystal clear about & and *. Thx Tim, was struggling with these two for a while.

[@alreadydeadfunk]

When I started my journey into programming, I have come to terms with stark difference in using parameters by reference from by value itself. It was in VB. But it gave me a understanding of what a difference that simple addition of a few words in syntax makes.

[@MaximRovinsky]

Cool. As always absolutely crystal. Thank you.

[@rayensabandar8392]

best line so far, "now, I actually got the pointer of the pointer when I did this, so I said &pointer which is a pointer to a pointer now I know that seems confusing, but this is pretty much telling me where the variable pointer is storing the pointer to toChange"

[@dr99tm23]

the pointer of the pointer 😱, thank you for this clear tutorial

[@publicuser993]

i wasn't able understand when i was learning in c/c++ but you teached me now thanks tim

[@kenocontreras]

I finally understood pointers and dereference after watching this video; thank you!

[@fikoredha5557]

Dude, your explanation is stunning. Thank you so much❤

[@2cmarx]

FANTASTIC video. So clear. Great examples. Thank you

[@techcode_man]

excellent explanation. 👍 And your & was perfect too 🤣. Well done!

[@victorrodriguez7705]

amazing teacher an amazing video

[@Sergey_Latyshev]

'fmt.Println (&*&*&*&*&*&*&*pointer)' is a valid line btw.

[@mayurnagrale5798]

you are really awesome at explaining concepts

[@ma34529]

Very useful, thank you.

[@randydouglas434]

Very well explained.

[@Blue-Scorpion]

Introduction of pointers seems like a legit crash course to hacking... :)

[@gazm81]

brilliant explanation, thank you

[@_joaopaulo]

ótima explicação meu cria, tmj

[@edgarlip2]

awesome explanation !!! 10x !

[@alejandrogomez8766]

Hi Tim, I'm learning Go and I found your videos very useful for that. I'm finding the topic of concurrency some difficult , do you think you can make a video on this topic?

[@time_traveling_avocado]

Good point!

[@johnbhosale]

It's a good explanation. Thanks!

[@nadzarmuttaqin6613]

youre the best! thanks you very much

[@Anu-vp9um]

Thank You , Sooooo much , I finally understood this topic :)))

[@kevinl.9657]

2:22 Why is your vscode so slow? It's not just in this video but for other vids in the series too.

[@mikecon4097]

it's not VS code that is slow, it is because of the extensions that we have to install with go that makes it slow...since it is statically typed language, which means you have to check all the things before you compile, this job is done by the Go extensions

[@rasem3259]

Hey man i have a question, what can we do with Go, what's so special about it?

[@Pimphats]

thanks for the video

[@santiagocubillos83]

bro thanks i finally understand

[@sot_dev]

thank you!

[@khazartalibov7911]

Very good

[@kvelez]

Cool example: package main import "fmt" func main() { x := 7 y := &x fmt.Println(x, y) *y = 9 fmt.Println(x, y) toChange := "hello" changeValue(&toChange) changeValue2(toChange) } func changeValue(str *string) { *str = "changed" } func changeValue2(str string) { str = "Changed" }

18:40 Pointer inception

[@empire2742]

his teaching is like watching inception movie

[@OfficialNattyOrNot]

I look at the at the *&* as an address or pathway for the * dereference and inject a new value. Anytime I see a pointer to a type. (*string or *int) I immediately think I must give a pathway or address (&) for the pointer.

[@nikodemus7900]

loved it

[@JuanLopez-ss3mz]

Golang probably has the best mascot

[@christy]

nice but naming a string as string was a little confusing a bit because couldnt keep in mind which one is string definition and which one was variable name str vs string....

[@alwadud0196]

Awesome, thanks!

[@thatkidjyro7158]

Hi tim, Can you do a tutorial on how to plan out a program before you programmer such as making a class diagram from the project idea and spliting things up into classes and objects?

[@kimeg7294]

Will there be a video about goroutines and channels?

[@123aniruddhsiddh]

Getting back to c :)

[@piyushmahapatra5402]

Thanks! well,it is not confusing to me.I was simply scared of pointers

[@TheEducationWorldUS]

Awesome

[@jasonhoman6525]

Why not just have a function return the new value and reassign to a variable like in Java?

[@cuneytyaz9121]

when I finished this episodes I ran in the house repeating pointer pointer pointer like psyduck :)

[@RushAlvarado]

🍊 new ampersand

[@chickenmirchmasala2274]

Hello from india TIm....I heard u got the job in the microsoft How Is it going?

[@ACHTech20]

Not in comment section we are launching in reality 😂😂😂

[@holthuizenoemoet591]

in the real word, would it be better to just return the string?

[@AWriterWandering]

So basically it’s like using the “global” statement in python?

[@bigtymer4862]

Keep learning bud

[@cheenamaejafar]

changeValue2() is not even legal but thanks though, I get your point.

[@salman0ansari]

Pointer pointing to pointer pointing pointer

[@vsanwa143]

Hey Tim ! Love from India ❤ Could you please make a video on Biometric Identification using ML ? That would be really Helpful !

[@tumblrbulbasaur5698]

Let's build something with Go, Tim?

[@oxyht]

hahaha pointer, pointer, pointer :D

[@meizum1738]

Like 👍

[@GmanGavin1]

This looks like a weird way of doing global variables. I don't get the purpose.

[@zackjames2409]

👋

[@xhjb4ever]

coming from c, this was not that difficult (you even cleared some things up I didn't understand in c)

[@chickenmirchmasala2274]

hahahahahahahahahahahahahhaahahahahahaha
