21:Everything u need 2 know about pointers -Richard Buckland

[@CASMANWHAT]

i like this teacher's passion. helps learning.

[@ladywebber1726]

i finally get pointers

[@raminmdn]

This last hour watching this video was the best hour of education I had in years ! Although I previously knew about pointers, I didn't miss a second.

[@richy2496]

This guy really knows how to teach. Out of all the videos I've watched about pointers, this one clarified the concept at a fundamental level.

[@PapaWilk]

This lecture makes me unbelievably happy. Richard's explanation of pointers is simply brilliant. He then performs some hilarious magic tricks and even rewards his students with 256 Mars bars. This is amazing!

[@Winged4Ever]

Totally gonna watch his lectures instead of ones that I can listen on my university, cause this guy's explaination skill rocks!

[@supaponhia6864]

You are the best professor in the WORLD. Thank you for sharing video on youtube.

[@aryamankarde473]

Nothing between these walls ever leaves this walls, loved your confidence sir.

[@Gelar93]

Wow this guy is genuinely interested in teaching, he was so good that I, who has a hard time focusing in a real class, sat in front of my laptop and watched it all in one setting with focus. Wish more professors were like him.

[@ChaosRevealsOrder]

WILLIAM such a good question 17:45 . I was searching for hours on internet WHY,WHY,WHY should we use pointers instead of normal variables. Mr.Richard is an amazing teacher

[@s3bbe1337]

I wish my professor was this enthusiastic!

[@3333218]

Finally understood pointers !! Best lecture ever. Truly educational.

[@paulmaxwell-walters8861]

Had the pleasure of meeting and attending lectures by Richard Buckland at UNSW. He is a legend and a brilliant, well loved lecturer. An asset to the university.

[@vitamink3]

Incredible! I spent last few days trying to understand pointers and this video explained it so beautifully. He not only explained what pointers are but also why do we need it.

[@krissapkota715]

ur awsome..non of my teachers are like u..they never teach us like this...they just gives me power point slides and say me to do everything...this is very helpful to me...thank u so much..

[@c99tutorial]

Jump to 4:18 to go right to the pointer discussion.

[@nishilshah140692]

But you'll miss out on the best part

[@bharathkumar-ji4if]

thank u

[@conradnal8934]

Fortunately I've started to read the comments while watching the video. Thx man

[@vedranart]

Oh darn, when I see proffessors like this Im sad that theres not more of them like this one, great study, fun explaining of things, and compairing things from everyday use with virtual things. That was a nice hour of great education!

[@bako3178]

Wow. I've been looking everywhere for a good pointer (pun intended) to pointers, and this by far has to be the best. Cleared up everything I was unsure of. Amazing lecturer!

[@xanderlewis]

14:53 This example is enlightening. Thinking about it will teach you a bit about how C compilers usually work. They usually have a notion of 'lvalues' (expressions that can appear on the left hand side of the assignment operator) and 'rvalues' (expressions that can't). In his example (&&&***x), we'd have to assume that x is at least an n-fold pointer (so that we can dereference it at least three times). We can then apply the reference (&) operator once to get the address of this value, but the second use of & is where it already goes wrong. At that point, we're trying to get the address of an rvalue - something that doesn't live at a memory address, but is just an expression floating around ready to be used. If you try it in C, it won't even compile. He suggests trying the other way around (***&&&x), but this has the same problem at the second use of &. One way to do something that WILL work is to try declaring x and then successively declaring pointers to x, pointers to this pointer, and so on. If you do this, you can successfully dereference the final pointer three times to get back x. TLDR: any occurrence of '&&' is going to fail.

[@AndroidOO3]

Like the fifth video I've looked up, this one has taught me everything i could want to know at this stage and more. This guy 's a great teacher!

[@mdmjwarner]

Wow, months of studying c and c++ = 0 understanding of pointers. 48 minutes of this guys lecture and I can use them with ease.

[@Bikaln]

Just loved it...understood every bit of pointers..undoubtedly the best professor ever. Please don't stop the good work and keep on uploading his lectures..we'd be really grateful to you!!

[@zerox227x]

ok i'l admit i thought i was done for in coding C. discourage and unmotivated because no one could really teach me well and i tried all sorts of tricks and tips to help me learn so i wouldn't be a burden to anyone, but after seeing this vid about 1 to 2 hr later i fully understand the subject that cause me to drop my class because it was too heavy in use. now im confident that i will ace my class up coming semester thank you his teaching style make you understand it perfectly.

[@big_lawyer]

For those here in 2023, hit the like button😅😅😅... I totally love this Professor's passion. He made Pointers absolutely look easy peasy. Thank you Professor Richard

[@justcurious1940]

why lawyers learn C🙃

[@big_lawyer]

@@justcurious1940 because lawyers have to know a bit of everything 😂😂😂

[@justcurious1940]

@@big_lawyer make sense

[@rohitmundada703]

Wow.... That's a beautiful lecture that surely removed all my doubts about pointer... And the guy makes things quite simple and easier to understand... Great job Sir...

[@medievalogic]

The quality of teaching is just insane, everything is so clear, i wish all of the colleges in India would teach this way :/

[@knownuser0815]

note to self: x is actually )( and & is actually 8

[@aya6816]

or gamma

[@steveokinevo]

More teachers like this guy needed for sure. Things get complicated when ya look at stuff like int **p1 / array of pointers / pointer to an array of x / function pointers, etc... list goes on.

[@s.d.gentry1354]

one of the best explanations I have seen about pointers to pointers (the crazy exam question example).

[@say-cred]

BEST EDUCATIONAL VIDEO I HAVE SEEN BEST LECTURER I HAVE SEEN AMAZING VIDEO AMAZING MAN 10/10 THANK YOU SO MUCH

[@MrCavitysChessCorner]

Watched the magic tricks at the end out of respect for quality lesson -- ended up learning another lesson. Thanks for making this -- it was really really helpful.

[@anttihaapala4579]

"In other languages, [scoffs] you write like this: p1 is a pointer to int, but in C we write it like this: star-p is an int." Brilliant!

[@jaken82]

I love this guy's passion and energy. I have been trying to get my head around pointers for ages and just avoided them. Now I understand!

[@VahiMangai]

Hope he hasn’t started another sars equivalent Hunh, how uh, serendipitous

[@vineethk8516]

Watching this video in quarantine

[@dolessaymore]

Joke didn’t age well

[@JeebuJacobThomas]

Excellent way of teaching... Not just pointers.. but infact anything for that matter!

[@francoc3495]

I wish I had him as a professor. This one video has helped me understand pointers than prior professors or textbooks.

[@theyugesh388]

what a lecture!!!!!!!! SO MUCH DEDICATED IN THEIR WORK HOPE U KEEP UP THE GOOD JOB:)

[@tanjagray9954]

Brilliant. Thank you so much. I've gone over the lecture material for my own uni so many times trying to grasp this. That was so clear.

[@mirlamontano6640]

I finally understood how can I use pointers, great lesson! (also, the teacher is so sweet c: doing magic tricks and bringing presents hahaha aww) thanks for uploading this!

[@msven]

Great stuff! Our class didn't go into the usefulness of it and now it makes SOO much more sense. Thanks!

[@joch3085]

This is way clearer than the lecture I had today about pointers.

[@SedaNurDoganay]

can't unsee the John Green in you :D Thank you so much for your clear expression of the pointers and thank you for your great passion!

[@FatmirSaiti]

This is the best professor I've seen so far! And I've seen a lot. I'm 35 and still studying, so go figure it :)))

[@AshwinPraveen]

I really really really enjoyed this class, He's like the liveliest teacher I've ever known!!!!

[@PrimitiveBaroque]

hands down the best video on pointers. amazing lecture

[@FrankBudino]

Amazing lecturer, some people are born to be teachers

[@Ashokgadeking]

A simple explanation of pointers. int* creates a pointer variable which can store the address of another integer. if we say int* a, a is now ready store the address of int b. To get the address of variable b, we say &b. So now we can say a = &b; . We should also remember that a also has an address and can be referred to by saying &a. *a returns the value stored at the address stored in a. That is b. Lol!

[@Ashokgadeking]

I have not touched java in a while. a should return the address and *a should give the value stored at that address if my understanding of pointers is still intact.

[@rishabhjain2404]

thanks for the explaination.. this was the only thing missing in the lecture

[@YoVille451]

That is &b *

[@TheShagans]

This was extremely helpful. Always nice to have that crazy teacher liven things up.

[@tomken5919]

Finally understand pointers now thankyou!!! Only lecture able to explain the purpose of pointers.

[@a1arjun02]

I feel exactly the same way, I studied computer science @ University of Hertfordshire. Complete SHAM, no C taught what so ever. All I learned was JAVA. Working as a Telecoms Engineer in embedded development. I find my self struggling, however this video cleared pointers up for me Thanks you Sir

[@jonathankim1999]

This guy is amazing! He makes things so easy to understand. Good refresher.

[@_slier]

actually pointers is easy.. what make its hard is,ppl always wonder why we learn it thank you richard for clearing this up basically pointers are use to overcoming scoping limitation

[@isaackay5887]

LMAO at that joke @0:58....watching this in mid-March of 2020 XD

[@justcurious1940]

Cables ?

[@CanadianMang]

Finally I understand pointers! This is a very good teacher.

[@AdvaTced]

One of the best guides, subscribed to this channel!

[@jethrobailey8358]

this guy is a top class lecturer!

[@RevolutioZ]

Wow, this guy propably made me find what im going to do after high school! Programming is so interesting!

[@harai6063]

i love professor voice and his teaching style.

[@SAURABHJAIN1989]

At 13:55 How *2 is 4? *2 should give the address of variable 2 (x) and that should be 10. As x was pointing to the value 2 at &x, 10. Isn't it?

[@LCaaroe]

Holy shit this is useful. I wish my teachers were as engaged in the subject as this guy is.

[@Nockoutz1]

This really helped me understanding pointers , I wish I had teachers like this guy.

[@ameegosar]

I'm confused at 29:00 if we pass the address of x and y isn't task expecting the address p1 and p2? Why do we write the argument list as value int *p1 and int *p2?

[@benjamenhartley8658]

didn't know John Green knew so much about programming. Cool guy!

[@filosofiadetalhista]

The same comparison crossed my mind! Hahaha

[@HK-sw3vi]

this teacher is a gifted one.

[@lub094]

i've watched a lot tutorials about pointers and i haven't understood them till now, THANKS !

[@MineCrafterCity]

I thought this would be difficult to understand, but you explain very well. thanks!

[@GGShinobi77]

what an enthusiastic performance! you can see he's doing it with passion and is having fun. An excellent teacher. :) And also thanks a lot! I've always felt that the use of * was inconsistent in C, thought that it was different when used in declarations compared to the rest of the program - until that great explanation! :))

[@rickyoswald]

@axelasdf The pointer is the first element of the array. You can fall off the end of the array (into other memory). I think stopping it falling off the end is a compile-time trick, but I am not 100% certain of that.

[@naruto-4990]

at 14:58 if we print &x (where x = 2 also there is a 2 in cell no 1) we get the result as 10 but if we try print &6 as seen 16:18 we cant do it?, i am so confused can somebody explain?

[@TheIndividualOne]

Amazing professor, crystal clear explanation! Kinda looks like wilson from house

[@swatisharma765]

If only we had teachers like you! Thanks a ton for this!!!

[@king38344]

Awesome style of teaching, learning made fun.... Thank you Mr.Richard :)

Awesome.. The best teacher in world

[@0ldfashi0ned]

This dude is absolutely brilliant!!! Wonderful explanation!

[@videos2laugh961]

good lecture!! like the magic :) His passion is just awesome

[@intindse]

Richard is the BEST TEACHER EVAR!

[@Vishanseru9]

Now those are the kind of teachers we need!

[@bondservant4Him]

It depends on your coding style.. Ive worked with some C programmers who would instinctively only dereference stucts with (*list).push_back() to stay consistent with dereferencing more basic pointers. It all boils down to style.

[@myonlynick]

introduction to the concept of pointers. Cool video.

[@LUX1111111111111]

this guy is so talented in teaching!

[@tressaortiz2078]

Not the professor talking about a SARS outbreak from Hong Kong 12 years before COVID. really tripped me out to hear lol

[@Ahliddin007]

Thank you very much Richard! You really know the good way of teaching!

[@shadyganem5448]

"Hopefully I didn't start a SARS equivalent " lol

[@0011usagi]

This feel inside me, you're good for me Very comprehensive course, thanks for that

[@bondservant4Him]

not if you dereference it, in fact it makes more sence to declare it int *i because you will rarely call it by i except in the beginning when you point it somewhere.

[@websailor93]

This is so good! I finally understood the basics of pointers!

[@HM-fp4mm]

Could anybody post a link to the whole playlist or tell me how to find it? I seem to look for it, but with no success so far. Thanks

[@SameerBalasubrahmanyam]

Best teacher ever! How I wish he was my mentor :(

[@b992152]

Wow, come now, this guy is fantastic! I wish I could have a king of education like they have!

[@kennethafstedt6231]

Just great, it's a pity that my teacher wasn't anything close to this.

[@kadersniper]

this is the best tutorial ever i know how pointers works now thanks Richard

[@P_S_42]

my prof just read his code out loud for 60 mins without explaining it... thank you for uploading this.

[@BritchesBumble57]

I got confused at 13:40 X = 2, that makes sense, but why does it then go on to use the value 2 as an address, and look up the value stored at address 2? this part makes no sense to me whatsoever.

[@forbidden.404]

BritchesBumble57 Because the * operator specifies the variable as a pointer. X = 2, the variable X holds the value 2 as an integer, but when one uses the * operator, one's saying that X is a pointer that points to the Address 2. 2 stopped being an integer value and now is an address in the memory.

[@Foaman]

It would be easier to understand if the chalk were better. By the time he got to x, I didn't know that x was assigned to 2 because I didn't see the flowline encircling 2 and x.

[@EngRona]

Oh my God,,amazing;thanks is a very little word ;thank you very very very very much; God bless and guide you Rana from Egypt

[@DTX_]

Hell, what a great teacher. So passionate :)

[@sepidet6970]

cant be better explained as this, thank you so much.

[@qettyz]

This was a great tutorial for pointers! Big thanks for uploading this!

[@RandomGameHall]

what happens if we point to a pointer that is not a constant and that pointer is also not pointing to a constant value?

[@ephsonguakro4583]

I love this lecture........so much!!!!! Now I don't have to read my boring pdf on pointers

[@ganstabreakincity]

After 3 years of computer science in college (We study using java not C/C++) I understood pointers XD thank you!
