I spent decades writing C/C++ code daily, and the best bit of advice anyone ever gave me stuck with me that entire time relating to pointers. Not sure if it is in this video, as I didn't watch it all ... When you are reading the declaration of a C/C++ variable, read it right to left in English and the meaning is obvious e.g. What is a variable defined as ... int * const * Backward .. it is a Pointer to a constant pointer to an integer e.g. What is a variable defined as int [] ** Backward .. it is a Pointer to a Pointer to an Array of Integers Easy :)
This is actually really useful. I finally wrapped my head around pointers and this helps solidify my learnings. Thanks Tony! I’ll remember this comment of yours when I’m a super C++ dev 😅🥲
Note about doing stuff like: int* p; It kinda make sense to put the star next to the data type... because it's an "Int pointer" named p. This is fine as long as you declare only one variable per line. Some people like to declare multiple variables at once (I don't recommend doing this but it's doable...). If you do so, only the first variable will be a pointer: int* p1, p2; p1 will be a pointer to an integer... But p2 is an integer. This is why you should put the asterisk on the variable name instead: int *p1, *p2;
I completed this course in a week and enjoyed learning it all. Harsha is the best guru of C and C++ programming and I learned a lot from him. Harsha why so OP. I know that he is no more and he died on June 15 2014 at just age 32 but I know that he made underdogs the winner finally and inspired others to make many more Brilliant Programmers from whole the world and not just INDIA.

I have been working as a software engineer in very big semiconductor company and implement functional safe programs. Still i came here to learn something more about pointers and i wasn't disappointed.
I must express the greatest possible gratitude for this course. The material is comprehensive, well-thought out and superbly structured. All of my implicit questions (i.e. "I know that I don't understand something, just not know what") are vanishing rapidly, and I haven't even finished the course yet! Thank you, thank you! To listen to this course was probably one of the best decisions I've made as a first year in university.
If you're as confused as me after checking the size of A in the sumOfElements function (around 1:15:27) and finding that it yields 8 instead of 4, note that in x64 architectures pointers are assigned 8 bytes. Since A is technically a pointer in that context and that's why you'll get 8 bytes of size
The size of other types will also change dependent on the settings of the compiler. Even comparing with the same CPU, some of these are simply choice and this is why we have the "size of A" function to check that they are acting as expected. For example a "long long int" default could be 32 or 64 or 128 bits depending on language compiler and target CPU, and you can manually change this compiler configuration. This is because you may be compiling the same source code several times for different CPUs. ie for some cases int is 16b, short is 8b, and both long and long long types are 32; for clang and gcc default for AMD64 is int=32 and long-long=128b, but you could add a compile time flag to change the int to 64b or everything to 32b. Float names are more standard so a double is 64bit everywhere I have looked. But the "long double" can often create a mistake, some interpret long-double as IEEE-754 float128, some simply ignore the long and use 64bit double; and others interpret long-double as an 80bit "extended precision" float; 80bit matches the x87 floating point hardware unit that is combined with some CPUs. And a few terrible implementations (*cough*python numpy*cough*) have been known to actually use 80bit when you use explicit "float128" or "float96" keywords in your source. These 80bit floats may actually be padded with zeros to use 12 or 16 bytes of memory (96 or 128bits) to keep the typical 4 or 8 byte alignment of memory addresses and cache lines, but the x87 math unit only uses 10 bytes.
llo, I am from Peru, I am 25 years old and I have been learning programming for several months. And I wanted to understand pointers in C++, and this is the best VIDEO explained in detail that I found, Thank you so much!!! Now I even know how memory is managed in C++. Thank you!
This guy is one of the best instructors I have heard on the web. Speaks very good English and explains things in a very logical, easy to follow manner. Superior instructor. Great job!
He was one of indias greatest coders and a genius, he was fluent in multiple languages and was the red and highest rated coder from india dude was truly a prodigy, #RIP
This was very helpful, thanks! Here are some minor corrections: - At 0:41:00 : in the discussion of pointer-to-pointer, variable r should hold the address of q (=205), not the value of q (=215). - At 1:28:00 : print(c2[1]) is only possible via printf(c2 + 1) and this outputs 'e', not 'l'.
1:53:06 is the answer 3 logic: b is pointer to array b[0] de refferencing an array returns the address of its 1st element which is 400 *(400+1), solving the bracket first e have 400+1(4) //size of integer being 4 *(404)=>3
Very clearly explained. I did C programming in 1990 as a part of my university project (I am Mechanical Engineer). I thought that everything is forgotten, but when I watched this video, everything resurfaced as if I had studied all this just yesterday.

To Those who are wondering if its a good course to learn Pointers in C or C++ , Let me tell you ITS ABSOLUTELY AWESOME!!!! This is by far the most detailed and indepth explanation of pointers and how its stored inside memory. Also it deals with all the relevant functions like malloc, calloc, realloc, free , new, delete. Pretty much this is the most comprehensive and to the point Video you can find on pointers. I am pretty much at the end as of rn and I can confidently say, If you want to learn pointers either for development perspective or data structure perspective. JUST FREAKING GO FOR IT!!
The simple bubble sort loop at "Function pointers and callbacks" is slightly inefficient. I edited the loop to be a bit more efficient. Instead of ( i < n ) and ( j < n-1 ), I transformed it to ( i < n-1 ) and ( j < n-1-i ) This prevents unnecessary overchecking. Here are the resulting performance results of a practical 12-element integer array: {5,2,4,1,10,6,7,3,12,9,11,8} OUTPUT: 5 2 4 1 10 6 7 3 12 9 11 8 Checks: 66 (My code) Swaps: 19 1 2 3 4 5 6 7 8 9 10 11 12 5 2 4 1 10 6 7 3 12 9 11 8 Checks: 132 (His code) Swaps: 19 1 2 3 4 5 6 7 8 9 10 11 12 I don't know why but I always seem to nitpick on these things! Optimize, optimize, optimize...
1:32:51 In the while condition we're dereferencing c so that it can identify the null character and in the printf we're doing the same so that printf fumction can print the string .. and c++ is just moving the pointer to the next character(by default it point to the h of hello) so that loop can continue.
Thank you!!! I've been trying to wrap my head around the concept of pointers for the longest time, and this video definitely makes it stick a lot better. When I was taking my programming courses, my instructor kind of just brushed over this topic, but this requires a deeper, more in-depth approach.
I am studying computer science in school now. And we have C language in our syllabus now - definitely UA-cam has taught me way more than my school teachers. And now I am proceeding to learn the intermediate of C language by learning the concept of pointer. I have already seen the first chapter of this video and have found it quite useful. Thanks to the person who have explained every thing on that chapter in an easy way.😀
In pointer to pointer concept : Value stored in "r" is 215 which I guess should be 205 if not mistaken 🙂BTW very well explained ! Use of pen and diagrams really helps to understand things better. And course content is very well covered. Lucky to have this in my library .🙏

*Pointers were one of the topics I used to hate in school. I watched like 5 minutes of this video and I am liking the topic already. I have saved this video to my playlist and will watch this completely after my work today.*
can't forgot how my journey start with learning programming, i was try to learn the pointers in the time of traveling and i am just remember this moment and want to share it
As a python programmer the concept of pointers was the only thing which was difficult to wrap my head around. After watching only the first hour of this video I now have a much better understanding. Thanks!
One of the best if not the best courses I've seen on UA-cam, the explanations and examples are excellent. I'd recommend this course for anyone who programs, not just people who program in C/C++. You learn so much about how programs work and how to manage memory.
Great Course! I've finished it now and I can say I am more confident working with pointers than ever before. Many thanks for the work to make this explanation easy to understand. The next course for pointers in C i wanna check is titled "Pointers in C for Absolute Beginners" that was uploaded on this channel.
Pointer is a vital concept in understanding a lot of programming languages, for example, in JAVA, even though there is no "pointer" concept here, but the reference variable assigned to a new constructed instance is the interpretation of pointer in JAVA. So I think it can be kind of hard for people without C/C++ background to learn JAVA virtual machine, memory management etc.
First of all really these are greatest videos to many students, where several things were not understood, watching these videos make someone getting enlightened, i still remember I came to know about mycodeschool, and had recommended to several people but they didn't watch, but i kept watching, later I see there were no more videos, I was completely surprised what happened why this got stopped all of a sudden today only i came to know about the story. Really this is sad to know, but the work will remain as standalone masterpiece, with little time they made this impact if it had continued it would made an astonishing impact to several peoples around world. Thanks Harsha I wanted to thank several times but came to know about your story today. Thank you very much.
Thank you so much! I have completed the first hour and learned a lot! Thank you sir!!!!! God bless you all and your team for providing free content with outclass quality! Please keep up the good work. I am learning programming for a business project, and haven't found any better video lecture so far. I even tried some payed courses but this is simply on the next level. Thank you again!
Thank you so much for this great tutorial. It really helped me understand the topic. It also makes me appreciate languages like C# that have garbage collection.
I love that you have dedicated so muxh time to this. Pointers has been the point where I have dropped programming so many times. I can survive without it, but a proper walk through is great.
Thanks very much for providing this easy to understand and comprehensive account of pointers, datatypes and memory allocation. The importance of the type of a pointer has been missed in other accounts I've read. So when you increment a char pointer it increments by 1, when you increment an int pointer it increments by 4. All makes sense once you've watched this....
It happens when we point to a member of a struct. example: Color = (P-> MainColor) Pointers are very powerful, they allow you to use Functions and structs Vector also. as: Initializes "P" as function address. *P(param1,param2,etc). The explanation, although old, is helpful.
Really a genius way and made it so easy to understand the giant topic. I completed the full video without knowing who Harsha is!!! Really a great guy. RIP! more strength to the family and friends. Thanks to Animesh too :)
Nowdays: 18:23 printf("%d ", p); will not work for pointers, because %d is for signed integer. It has to be %p for pointer address. Also at 19:33 printf("size of integer is %d bytes ", sizeof(int)); %d has so be %zu or %lu, because sizeof() returns type size_t.
Thanks!. Great video to tighten memory handling. Goes right to my queue. But better yet the history behind. Gratefulness to myCodeSchool and glory for Harsha. Saludos.
I spent decades writing C/C++ code daily, and the best bit of advice anyone ever gave me stuck with me that entire time relating to pointers.
Not sure if it is in this video, as I didn't watch it all ...
When you are reading the declaration of a C/C++ variable, read it right to left in English and the meaning is obvious
e.g. What is a variable defined as ... int * const *
Backward .. it is a Pointer to a constant pointer to an integer
e.g. What is a variable defined as int [] **
Backward .. it is a Pointer to a Pointer to an Array of Integers
Easy :)
This is amazing, thank you!

the explanation of function returning pointers was the best. explaining by actually showing how the memory is allocated in stack was so good. thank you so much.....
So I have a job interview an hour later. Came here to refresh my concepts on pointers and memory management. My only regret is why didn’t I finish it earlier. Awesome content. Much love to mycodeschool.
Did you get it :D?
@@piesekleszekpiesek Thank You for following up 😄 I have completed three technical viva. Waiting for the call to final management viva. Let's see what happens. 😄🤞
@@monemahmed6830 what happened at the end :)?
If mycdschl continued their course it would be the most subscribed channel in cs courses.
this is probably the best video ever made on pointers.
*Pointers were one of the topics I used to hate in school. I watched like 5 minutes of this video and I am liking the topic already. I have saved this video to my playlist and will watch this completely after my work today.*
did you watch? do you know pointers now?
Have you learned pointers at school? We were only taught some basic concepts such as variables and cycles, and also some algorithms
@@geutk4162 Nope. I just relized I forgot to watch this video after work that day!
@@aravindkramesh haha
Well, it's never too late
I'm at 1:05:27 and I have already started fantasizing about impressing class girls lol😁😁
Thanku so much
The time I studied this in the early 2000´s, I had no rescue from youtubers. I think this is a valuable content
Studying for an exam to get into CS and this has helped me a lot. Thank you very much
good luck 👍 🍀
i did not mean this sarcastically btw lolol
@@missgirl8210 haha its all in good spirit!
can't forgot how my journey start with learning programming, i was try to learn the pointers in the time of traveling and i am just remember this moment and want to share it
As a python programmer the concept of pointers was the only thing which was difficult to wrap my head around. After watching only the first hour of this video I now have a much better understanding. Thanks!
You're welcome
It's truly astounding how easy the internet makes learning these days. Thanks for the tutorial, my guy.
RIP. The legend he was. Humblefool.
Is he dead ?
@@TheTariqibnziyad who died?
@@TT-ud5gf Harsha, the guy who was presenting the video 😢
@@TheTariqibnziyad unfortunately it's been very long now. He was one of my initial gurus.
@@ShubhamSharma-tn3wm where is his page? How did we lose him?
I have been trying to wrap my mind around pointers for a while now. This video is priceless! Thank you! Thank you!
Harsha was a legend. Started my coding from his channel.
What do you mean, was?
@@johnnycincocero He died in a car accident 😭
@@johnnycincocero Please read the story put up in description link. Its an amazing one.
@@jatinthakur4252 omg
@@jatinthakur4252 Damn. Sorry to hear that.
One of the best if not the best courses I've seen on UA-cam, the explanations and examples are excellent. I'd recommend this course for anyone who programs, not just people who program in C/C++. You learn so much about how programs work and how to manage memory.
I fell asleep watching family guy and woke up ending this now i know how to code perfectly
Great Course! I've finished it now and I can say I am more confident working with pointers than ever before. Many thanks for the work to make this explanation easy to understand.
The next course for pointers in C i wanna check is titled "Pointers in C for Absolute Beginners" that was uploaded on this channel.
you know it's gonna be a good video as soon as you hear the indian accent , god bless everyone that teaches us something important
Köszönjük!
Pointer is a vital concept in understanding a lot of programming languages, for example, in JAVA, even though there is no "pointer" concept here, but the reference variable assigned to a new constructed instance is the interpretation of pointer in JAVA. So I think it can be kind of hard for people without C/C++ background to learn JAVA virtual machine, memory management etc.
First of all really these are greatest videos to many students, where several things were not understood, watching these videos make someone getting enlightened, i still remember I came to know about mycodeschool, and had recommended to several people but they didn't watch, but i kept watching, later I see there were no more videos, I was completely surprised what happened why this got stopped all of a sudden today only i came to know about the story. Really this is sad to know, but the work will remain as standalone masterpiece, with little time they made this impact if it had continued it would made an astonishing impact to several peoples around world. Thanks Harsha I wanted to thank several times but came to know about your story today. Thank you very much.
best video ever. Keep doing this kind of videos, where you get inside of difficult topics and make it easier to us. Thanks FreeCode.
This teacher is one of the best coding teacher I have ever seen... Unfortunately he is no more.. Rip legend
Animesh and Harsha, you both are all time great for me ❤️
i've been struggling finding the best explanation for pointers but this video really is the best. props to Harsha
Thank you so much! I have completed the first hour and learned a lot! Thank you sir!!!!! God bless you all and your team for providing free content with outclass quality! Please keep up the good work. I am learning programming for a business project, and haven't found any better video lecture so far. I even tried some payed courses but this is simply on the next level. Thank you again!
Woke up from my sleep with this on, I can now fluently code in c++
I woke up here
Me too 💀
This is the best teaching I have ever seen, and it really "free" a lot of problems in my brain.
very informative , detailed explanations which are very useful to understanding this difficult concepts
I presented my final project and this video was fundamental for me to code it.
Thanks a lot
What a gifted teacher!
I know this stuff, but it was nevertheless a pleasure watching the entire video.
this is a Holly Grille valuable info about pointer. Well explained and well illustrated with examples. Thank you a lot
If anybody is confused at 38:38, the value of r should be 205 and not 215
That's what I was thinking. Thank you! :)
Really Really the Best video Video on Pointers !!
All Doubts on Pointers are Cleared !!
Thank You!!
So much!!!
I really needed to learn more about pointers, thanks free code camp❤️
Thank you so much for this great tutorial. It really helped me understand the topic. It also makes me appreciate languages like C# that have garbage collection.
I love that you have dedicated so muxh time to this. Pointers has been the point where I have dropped programming so many times.
I can survive without it, but a proper walk through is great.
This is brilliant! All case scenarios, in depth explanation... Brilliant! Thank you
Thanks very much for providing this easy to understand and comprehensive account of pointers, datatypes and memory allocation. The importance of the type of a pointer has been missed in other accounts I've read. So when you increment a char pointer it increments by 1, when you increment an int pointer it increments by 4. All makes sense once you've watched this....
Thanks Quincy for this course. I know you're behind this great idea of bringing their videos together to make this all-at-one-place video.
who is Quincy? btw this gold video is 8 years old made by animesh sir
@@sra9an938 Quincy Larson is the founder of FreeCodeCamp
@@gamoholic7653 oh yes thanks, I got to know that little late
It happens when we point to a member of a struct. example: Color = (P-> MainColor)
Pointers are very powerful, they allow you to use Functions and structs Vector also. as: Initializes "P" as function address.
*P(param1,param2,etc).
The explanation, although old, is helpful.
finally finished lecture ...My college takes atleast $50 for this course and only taught starting 30min of this lecture
The pace could not be done any better. This is simply the best video on the subject
Their course was the first course i did 5 years ago for pointers and data structures. It was really great course.
Really a genius way and made it so easy to understand the giant topic. I completed the full video without knowing who Harsha is!!! Really a great guy. RIP! more strength to the family and friends. Thanks to Animesh too :)
well done! your usage of a tablet/pen helps a lot to visualize concepts like stack, and heap.
Best pointer tutorial I have seen thus far.
love the fact that i can go fullscreen on my ultrawide with this video
Nowdays:
18:23 printf("%d
", p); will not work for pointers, because %d is for signed integer. It has to be %p for pointer address.
Also at 19:33 printf("size of integer is %d bytes
", sizeof(int)); %d has so be %zu or %lu, because sizeof() returns type size_t.
Thanks!. Great video to tighten memory handling. Goes right to my queue. But better yet the history behind. Gratefulness to myCodeSchool and glory for Harsha. Saludos.
So clear saved my from desperation i love you so much please dont stop posting these valuable tutorials.
This was very helpful. It helps fill out some gaps while learning structures, and other concepts. Thank you very much to the team who made this. 👍💪😎🔭📡
