i like this teacher's passion. helps learning.

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.

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!

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

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.

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

I wish my professor was this enthusiastic!

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

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

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

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

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

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

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

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

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

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..

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!

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

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!

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.

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.

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

this guy is a top class lecturer!

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.

"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!

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!

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!!

Amazing lecturer, some people are born to be teachers

this teacher is a gifted one.

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!

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!

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

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

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

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

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!

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.

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.

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.

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!

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

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...

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

Now those are the kind of teachers we need!

Richard is the BEST TEACHER EVAR!

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

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

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.

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

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

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

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

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

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

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

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

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

wish i had a teacher like him

Awesome.. The best teacher in world

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 :)))

guys... sshhh shhhhh :)

the statement printf("%d",*7); near 10:00 won't work...because it is referring to value of 7. It should be an address. To make the things easy just modify your jargon for pointers a little bit. 1. call the * operator value of operator 2. call the & operator address of operator. for example: int a =10; printf("%d",*(&a)); now solve it with new jargon. Read it loud "content of address of a".

This guy reminds me of Walter White

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

this guy is so talented in teaching!

hands down the best video on pointers. amazing lecture

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.

i love professor voice and his teaching style.

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

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

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

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

One of the best guides, subscribed to this channel!

introduction to the concept of pointers. Cool video.

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

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

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.

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

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

Great explanation of pointers :)

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

@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.

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

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

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.

Title is a misnomer. Should be 'Basics on Pointers'. Did not cover protecting array constants with 'const', pointers to multi-dimensional arrays, pointer addition (which he states), pointer compatibility, and was weak on declaring and assignment of pointers. On the plus side, he was not boring, and did cover the basics with good visualization.

This is how they really teach!!!? Wow! It's so much fun.

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?

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.

This dude is absolutely brilliant!!! Wonderful explanation!

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?

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

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! :))

EXCELLENT lecture!!!

I´m coming from germany, and my english isn´t that good, but to be honest i understand everything ! Really nice Teacher !!!

I ACTUALLY LOVE THIS MAN.

great personality.. Richard sir you are awesum

Lol, this man can teach!

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