Don't know if you are trolling or for real.. Universities exist to guarantee a certain quality standard, if you have a degree there is a guarantee that you meet those standards and know specific things.. There is no standard for people who learn online, they might be geniuses, but could also be "garbage" programmers.. ;)

Very informative! Really liked your drawing of the 'heap' and the 'stack'. Made it much easier to understand what is going on.

I've been reading Dr. Bjarne Stroustrup's book on Programming and referring to your videos often. I must say that I wouldn't probably be able to go through that complex book if it weren't for your clear, really lucid explanation of concepts. Thank you so much!

Super clean and easy explanation. Absolute masterpiece if anyone wants to understand pointers, dynamic memory allocation, stack and heap.

i ‘ve watched many best tutorials but this one made my way clear that i won’t ever forget how stuffs are allocated in the memory. Thanks sir

Just started programming and c++, memory was the first topic that I would first struggle to understand and get my head around and this video really helped :) thank you so much

This video is 7 years old and it is the best explanation I've yet encountered on this topic. Thanks.

This was the best educational video of explaining pointer and dynamic memory. Everything about pointer and dynamic memory is so much clearer now. Cheers !

Your efforts are paying off for more than 10 years. This video helped me a lot. Thanks !

I have never seen anyone explain this more clearly in my life. You are amazing!

DUDE I literally got a 100 on my exam because it was based off of memory diagram questions. Thank you!

Since C++11 You should not set a pointer to NULL, but rather to "nullptr".

Zoran Jovanov Not really. It was replaced for a reason. Imagine having two functions, void Func(string* aStr) and an overloaded version called void Func(int aNum). If I call Func(0) or Func(NULL), Func(int aNum) will be called. But if we call Func(nullptr), then Func(string* aStr) will be called, which we want as we're dealing with pointers.

NULL is just constant of 0 difference is NULL is defined with #define and nullptr is a const variable it was replace just to tell you that you are assigning it to pointer and to avoid some memory leaks :)

Scias yes but i ment only when u delete pointer so it wont be dangling =0 is just fine.

finally understood the concept...this video helped me a lot...

This helps me to understand the operations of 'new' and 'delete' . Thanks.

I was debating dropping my major until i found your videos, thanks for the help/motivation!

i got the clear idea of what is heap and how to handle new/delete operators and that too dangling pointers and garbage collection. Thanks for this lecture.

He is so simple in explaining complex concepts. thank you

Taking reference from your videos and C++ Primer both, best learning combo ever!

I love the drawings! You helped me understand what a stack frame is! Thanks!

This is a great video, the drawings really help to make the concepts and idea take concrete form for a begginer

Excellent video. You really capture the big ideas well.

Excellent explanation with the graphics. Please make more videos. Thank you

One of the best explained topic I ever seen

Woww😲 had been struggling with this topic for months.. well explained..Tysm.. you're awesom!!!

Such an amazing amazing amazing amazing amazing amazing tutorial...hats off

Thank you so much bro! Your drawing and interpretation of heap & stack made me understand the whole thing :D

Very informative video! Thank you so much!

Thank you so much for the tutorial. Dynamic Memory Allocation has been kind of a plateau in my C++ learning, and you explained it very concisely. Very well done.

Thanks for the video! It's a lot easier to program codes in c++ using memory allocation with your explanation visuals in mind! Thanks a lot! :D

best pointer explanation ever :D

very precise and informative!!~ thank you so much!!

Wow. explained in such simple terms. Thank you so much.

This was crystal clear .Thanks

very clear clarification. Thanks man

I loved your explanation. Thank you!

Short and informative, thank you!

This was a great explanation. Thank you!

The best video I've ever watched about pointers

Thank you very much. You really helped me. May God guide you and increase your knowledge .

Thank you so much. I watched a few of your videos today, and I found them very helpful. Clear and concise, really impressive!

a legendary explanation. thank you sir.

the best 13 minutes of my life

I love your tutorials. You explain thing soooooooooooo clear. Thank you soooooooooooooooooooooooo much.

Very informative video! Keep it up.

thank you so much I never get to understand pointer as I did this time, thank you again

You are incredible! Great presentation! Keep it up!

Thank you! You really explained it well and it helps me a lot in studying :)

Thanks for such an easy explanation

very great explaination. thank you

Thanks man, really good explanation!

great job! thanks so much for making this video :) helped me with my homework

Thanks for the video its NUTS & BOLTS :). I am trying to learn how to make a program and everyone says C++ is powerful because of memory management, but now that I am learning it they keep getting away from the nuts and bolts and pretty soon everyone is talking about packaging everything into things already programmed in other things... boxes within boxes and which box to use... Before too long I don't even know what nuts and bolts are actually in the boxes or anything from anything. So thanks

Awesome explanation

Thank you so much for offering high quality tutorials!

excellent explanation!

Agree, finally understood the concept

Thank you for explaining it so well!!!

outstanding sir.

Thank you. I understood everything you said.

The stack memory is managed by the program/compiler Dangling pointer = pointer that points to something that no longer exists. you can assign a dangling pointer the value NULL or 0 When a function exits its memory on the stack is deleted.

Very Useful. Thankyou

Wow great video! I completely get it now :) Doing a quick review, haven't touched this material in a while haha

Thank you so much for your effort man! your doing such a great job... I have only one question, is there any way to get your notes for the videos you ?

You are just awesome! thank you so much!

Thank you so much! I finally understand why pointers are useful! I have been facepalming over them ever since I first read about them.

Thanks, this was a really good explenation.

Greate explanation.

really nice article about memory

Yea nullptr uses in C++ from the book. Very good video very clear. Better than the book.

This is great man thanks a lot

really really really helpful! thank you!

Very very good. Thanks

thanks friend greetings from Colombia :-)

Very good, i like it much !

Holly shit you explaint it like no other, literally 15 min and I understand it all now! Thank you!! :D

OOOOHHH MYYY GAAAADD! Pointer's too simple now that I learned it from u

I finally understand this concept

Great video

Thanks now it all makes sense.

I understand it now, thanks for the video

Thank you THANK you THANK YOU!!!

really informative !! thanks !

I'm actually kinda scared to start practicing on pointers... I don't really understand them to well...much reading up on to do. But the last example you did with the function sparked a question. If you close the program, then what happens to the garbage? Does it get deleted? Cleared?

When you start your program - OS allocates some memory for it, then your application messes with memory that it is given(storing everything it needs - text, globals, heap, and stack). After it terminates, OS is responsible for cleaning up the mess, so memory will be freed

1. Theoretically - yes, practically - not really. The address that contains garbage is still occupied, so nothing will be written there by the program or OS automatically unless you use a delete operator to tell that the memory address is now available for use (it doesn't really mean that the value is deleted, it might still be there it just marks the address as available and might or might not be used again). The only way to replace the value guaranteed is to get the address, and to do so you have to manually increment memory addresses and check whats in there, but another problem rises - how would you know what is a garbage value? For example 53453453453 can mean garbage or actual value, it can be an integer that fits entirely in a single memory address or can only be a portion of a large object that continues in the next address. That leads to your next question 2. This one is even more complicated, since it depends on implementation of memory management in OS, in general heap is not guaranteed to be contiguous, however more than often you will see the opposite if you write a program to demonstrate it (the program is tiny and will terminate quick so the whole heap will be within certain range). Also all(?) modern OS use virtual memory technique, meaning that the memory used by a process is different from actual physical addresses where stuff is stored, and on top of all that paging and swapping are used to move memory around. Hope that helps a little bit, also note that I am not a C++ guru and might be wrong on something. Please read more about terms I used in my answer to get a better undestanding

You dont have to start with pointers, they are not needed at all until well into mid-tier knowledge. When you need to move beyond the memory limit of a stack you will know 100% enough.

thank you ! you are my teacher !!!

The "garbage", i guess is called "memory leak". Good video!

Great explanation. Is it possible to find size of the reserved memory for a specific variable in heap? For stack, it is sizeof() but what would be the case for heap????

amazing video!!

It was Amazing!! Thanx a lot :)

Thanks for the info:-)!!!

liked and subscribed thank you.

very useful video....carry on

you are awesome sir

this video explains alot. however, as a beginning, I still have a few questions.1. Variables stored in the stack DO have variable names and variables stored in the heap DO NOT have variable names, correct?2. What is the advantage/disadvantage of storing variables in the stack vs. in the heap?3. This is probably a stupid question, but why is it necessary to have a stack and a heap? Why can they not be considered one and the same? Then pointers would not be necessary?

Hi :) thank you for such a wonderful lesson. Just a quick question: is there a to get *p to point back to memory address 500? Like say for instance we point to 500 (after we allocated space at address 500) and then we point to 700 ((after we allocated space at address 700). Can pointer p point back to 500?
