Please, use "an" instead of "a" before words that begin with a vowel: an operation

[@morfisiuslizerro6400]

beautiful Saldina, sorry!

[@sayaleeambulkar8863]

Everything seems easy when taught by you😌

Finally, I have found the best teacher in the world!

[@licinio3]

I saw several videos in this channel and I think it is a great course/s to learn, to remember several essential concepts of programming. Great! Many thanks :)

[@optane3336]

you're soo underrated you deserve a lot more subs than you have right now

[@sofiavaleriatorochambi4234]

This just blew my mind, I'm learning c++ for a project, the reference code I found is so confusing so I was just watching some youtube videos to understood, and yours is really well explained, thank you! It was an absolute mind-blowing to me 🤯❤

[@muhammadumernadeem725]

Beautifully explained + You said Derefrenciate 5 times.

[@CodeBeauty]

Hahaha, I filmed a couple of videos that day and edited only this one so far. I hope that there will be no "derefrenciate"-s in the other ones. 🤭

[@muhammadumernadeem725]

@@CodeBeauty These minor mistakes doesn't matter in front of all the efforts you are putting in these videos.

[@patrickgemayel4326]

Thanks!

[@making.fronds]

I'm starting my final year papers at uni, my algorithms and data structures paper uses c++ and the way they explain things is soooo much more confusing than you do!! I felt like you explained linked lists SO well that I'm going to watch this whole pointers series, even tho I've already learnt them, I don't fully get it. I hope you have content for all the other topics we learn!! Thank you!!

[@CodeBeauty]

I'm sure that you'll learn si much from this course, and that all the pieces will come together and complete your knowledge of pointers ☺️☺️

[@AKhan-3]

One solution for the last part is to use: sizeof(luckyNumbers) or luckyNumbers.size() in the for loop condition. So we can avoid accessing memory location not belonging to us.

[@k2305Pawan]

It will cout 20 instead of 5, try int getArrayLength = sizeof(myNumbers) / sizeof(myNumbers[0]); cout

[@painsme2]

I know you mention it's tough recording video's while trying to break the language barrier. I have no issue understanding anything you say nor do I even notice the little thing's that you mention in these pop ups about some mispronounced word. I never even notice and I'm grateful that you took the time to do it in such a manner. I would have missed out had this been in any other language as I'm unable to speak any other myself. Cheers!

[@bbains963]

For the first time in 4 months, I'm finally able to understand pointers thanks to you.

[@danwatgu]

Thank you very much!!!! The best classes I've received.

[@MohamadrezaVafaieekia]

One of the best course's I have ever find! tnx a lot from Iran❤️

[@CodeBeauty]

I'm happy to hear that. Many greetings for you! 🥰🥰

[@eyuelsolomon2625]

Thanks a lot Now I finally understand them I Feel I'm ready for tomorrow's final exam

[@Gary-vo9rm]

I haven't used c++ or computers in 15yrs. Kinda interesting to refresh -- especially from such a babe!

[@ruachmajiokkhor6103]

thank you so much,your voice is so nice even it leads me to understand easily

[@GitMike]

Thank you for the help, explained it very well.

[@leoespejo7437]

Such an amazing explanation. I was checking on a very well know online course, specifically for how to combine Pointers and Arrays and they include Stack and Heap in the explanation trying to clarify but that was really confusing then I found this video and this is very concise, straight to the point and very well explained, I loved it. Now I am ready to continue with me C++ project 😊

[@paulhendrix8599]

Thanks for the great video! Minor nitpick/addition (from my understanding, please correct me if I'm wrong!) regarding the array overshoot at 10:07: The data accessed there is "not ours" in the sense that it doesn't belong to the array, but it's not really "someone else's" in the sense that it belongs to another program - the memory belongs to the program being run. If you try to access memory outside of that allocated for your program you'll get a segmentation fault - you can try this out by overshooting the array by a larger number (2000).

[@IrisFlorentinaA]

did as you said!! got this " Exception thrown at 0x009A6010 in Pointers and arrays.exe: 0xC0000005: Access violation reading location 0x00F61000. " thanks!!!

[@danhhohuu8766]

these course are very clear and the language is clear to for french guy

[@foodtips8515]

Best coding lesson ever

[@culu37]

I wish I found this channel sooner lol

[@BrothonAlone]

Excuse me teacher system(pause>0) What's it means? please kindly explain thanks.

[@Tony770jr]

Very thorough videos... Thanks!

[@maxim25o2]

curly brackets are shortened for pointers, the long usage is *(luckyNumbers + 2) and short representation for this same is luckyNumbers[2] . Functionality of that two is exactly this same, but second one a lot of times is misunderstanding by new peoples who start learning C++ and C. Peoples teaching arrays forget to mention that this is dereferencing pointer style, that so important stuff causing peoples who try to learn it are doing mistakes in programming and have hard time to fixt that. Especially when function come in to play. Passing array of pointers using that quotation luckyNumbers[2] cause problems, when is time to deference it.

[@Dannnneh]

5:18 what hotkeys do you use to comment out the highlighted text?

[@CodeBeauty]

Hold Ctrl and pres K and C 😊

[@kultureislame]

5:18 what do you press for commenting the lines Saldina?

[@agreensh]

Just to note, your last example (going past the end of the array) may cause a crash, and not do the cout (depends on the memory layout eg the pointer could go into reserved memory).

[@CodeBeauty]

Good point! In higher-level languages this is handled, in C++ you have to take care of it yourself and must not go out of the index range of the array. 🙌

[@onurolce]

@@CodeBeauty That's Operation System's main job, put borders between applications :)

[@dasoft]

Ca you explain more clearly why we should be careful with memory allocation?

[@lexico9191]

Do you by chance have a video covering sorting and searching values through an array?

Whoaa this sure will do a great job tomorrow in my exam lol. Awesome explanation!

[@utpalkumar100]

Great Video! I just have one confusion about the usage of the "system("pause>0");" at the end of the main function. Why is it being used as this is not a GUI application where the pause is important?

[@DobbynciCode]

Dang. That one's a good explanation for pointers and references. One question, lists doesn't have element invocation using square brackets. Can we use *(array+integer) to traverse on it?

[@nines7588]

what an explanation mam! ❤️

how do you make the terminal pop up with visual studio code when you run the program?

@codebeauty 0:52 how do you put space between characters like that? whats the keyboard combination please?

[@luzten]

its the IDE doing it, you should avoid those type of practices, in fact, it's recommended to learn to code on a text editor such as Vim, mcedit etc when you are learning so you can learn the good habits from the start.

[@kultureislame]

@@luzten programmers are lazy bro yk

[@joborfrederick4312]

Saldina please how do you make the program read the first index of an array as one? That’s if you are writing a program for inserting a value at a specified position in an array and you don’t want the output to be strange to the user.

[@107vijayanand4]

a nice video tutorial again, thanks :) But please keep going to make videos about pointers more such as how to pass it to function as a parameter, how to create char pointers.

@@CodeBeauty very cool, so we are going to watch them soon :) I don't know how much effort do you spend for edit videos but you look expert to teach us these topics :)

[@parttimedude5440]

[@Programming_Buddy1]

Love your videos! I actually understand what is going on! lol

[@PunkUntilThe3nd]

Just out of curiosity: Is there any reason to use those clumsy, uneasy and non-canonical C-Arrays over std::array and std::vector? Most of the discussed problems in size-assertions, usage in range-based-loops and most importantly conversion from T[ ] to T* in return statements are solved for about a decade. In all other regards a very good video, just append the reference to std::array in a prominent place if possible.

[@joborfrederick4312]

Please what IDE were you using here?
