You are a man that made 17 minutes feel like 3 and enlightened me every step of the way. I not only salute you, but respect your work immensely. Well done. Subscription more than deserved.

*My takeaways:* 1. Stack 2:12, stackoverflow 5:45 2. Heap 7:35 3. Heap is also called dynamic memory, using the heap is referred as dynamic memory allocation 8:56 4. Heap memory has nothing to do with heap data structure, but stack memory is an implementation of stack data structure 9:17 5. Dynamic memory allocation functions/operators: C - malloc, calloc, realloc and free. C++ - new and delete 10:00

Always had to deal with stack and heap, and I was unclear of the difference. This explanation and examples were kick-ass. Loved it and it was the best delineation of the stack and heap that I have ever ran into. Thanks much!

After months of intro courses skirting around this idea like it is some big scary monster, finally someone explains it in a simple way that is just so easy to understand. Thank you!

I've never encountered an explanation of this subject that was so easy to understand as well as covering so much material. Thank you infinitely

I sat through a 2 hour lecture on this subject and this video made far more sense than my professor did. Thank you!

Very good big picture video, you spent a lot of time prepping of this via examples. Thank you for spending the time to make the forest seem clear and not get lost in the details of the trees

Thanks for providing subtitles, I know it would hurt your ego to do it, but it really does help. :)

Your explanation is excellent thank you :) finally i understand. watched so many videos about this topic and yours was the best

Fantastic video, I would recommend to anybody having trouble understanding these concepts as they build off each other very well in these videos. Great job, sir.

Sir, you are the best. I have never met a mentor like you in my life. Keep educating the world and may god bless you. Thank You.

Wow. This cleared up so much confusion I didn't even know I had! I feel far more solid in my understanding of stack/heap/memory. Thank you!!!

The size of stack is decided during compilation. So, in most cases we do not need to bother about stack-overflow unless we write an infinite or very deep recursion. If we try to use too much of memory on stack and compiler can get to know about it during compile time (like very large arrays in C), it will give you error during compile time. Its just that if compiiler can not predict run-time behaviors like in the case of recursion.

For me, such topics should be exactly explained like you have here. Through actual examples of implementation of these concept and a visual representation of what's happening behind the hood. For me a picture does indeed say more than thousand words. Thanks!

You just explained away all questions i had about the reasons to use pointers, why pass by reference is so important and stack vs heap. Thanks dude!

It depends on the language, compiler, operating system and architecture. Typically, compilers would know about your local variables and function calls, so they can fix some stack size accounting most of the things except probably things like recursion that may go on infinitely. Once again, OS may also enforce some constraints. So,all in all its a thing of compiler and your system's design.

Hi Shri, Yeah, we will create more tutorials. Its just that it will take some time. Stay tuned :)

Well done. Much more coherent than the ones I have to speak to for problems with my ISP.

For english speakers, Heap can be thought of as a pile of data. It was called heap because it piles up data building upwards. The stack builds downwards (hence stack pointer references decreasing addresses as you build onto the stack) while the heap (or pile of data) builds upwards (meaning the addresses increase as you build onto it.

The drawings make it look like the stack is building upwards, though. This doesn't seem consistent with what you said

HI Ayush, my suggestion would be to start solving questions from HackerRank and mycodeschool ( the website) first. The main thing that I liked about mycodeschool is that it has many questions relating to implementation of C std libraries, which many interviewers ask. HackerRank because most of Amazon questions are direct links to hackerrank, so if you have solved hem in past, you will be in good position. Side by side start on leetcode . Leetcode is the goto site for many questions from Google..etc. My aim was to solve atleast 5 questions daily. Keep a notebook consisting of any solved questions that Tushar does/you do, it will help you a lot during interviews as you can simply go thru the answers from your notebook in a short span of time. During my interviews, i went thru the solved submissions on HackerRank and it helped me a lot . You can leave out DP, hard level graph and tree questions for later though. But you should be able to say the tie complexities, and why a particular data structure is used in any question you do. Most of my failures in earlier interviews was because I hadnt practised programming. SO evvn though I could tell the algo immediately, on white board I would not give a correct code in 5 minutes. SO ya practice a lot. My experience is from being interviewed as a fresh grad from MS in USA. I think in India the question standard are more tough :P Lastly , before any interview,,spend some time on glassdoor for that particular company and gp over the questions that people have been asked. That helped me a lot as well. Best of luck

Hi Him, Ok ! We will try to get one video for object oriented implementation as well.

Excellent explanation. Just one suggestion that, stack always resides higher then heap. It would be better if you would have drawn stack above the heap. Also stack grown from high to low and heap grown from low to high. These directions are important, and shall be shown.
