You're the best teacher on youtube because most teach but still don't make it as understanding as you do

[@muneeburrehman4690]

Though I've cleared my university programming course but your videos are still helpful in revision and sometimes you teach something new too.

[@bigcode4you299]

Good dai

[@JyotiSharma-wb1vy]

Thank you so much ma'am!
You can make any topic easy to understand✌️

[@abdulrahimjalloh363]

These days our university teachers can take more than 2 days without explaining such topics clearly. Mam, you saved my university fee. 😋😋😋😋

[@rkhgaming94]

but bro i think 6-8 minutes are enough for null pointer

[@mokkaclub6432]

Thank you for actively uploading quality content to learn in this pandemic
Lots of love from south✨

[@ankammaraochintala2509]

I am eagerly waiting for you classes mam, thank you for your knowledge transfer.

[@ankitroshan3005]

Great explanation of null pointer .

[@mudassarsiddiqui4112]

Excellent explanation madam❤❤
I am learning languages and your videos are very helpful

[@itpn7821]

but mam , it works even using * operator in null pointer in my compiler. I am using turbo C++ text editor.

[@karthick3899]

Hi Mam.. Your Lecture is Very Nice...But Try to you will make php, java script, Python..and relating the web development Topics.. Please Consider Upcoming Generation...🙏

[@technology5375]

But before that just want to tell you onething that if you want to coding you have go through Jenny's lectures😂

[@arvindkumarmishra3988]

I am in 3rd year now and after I am placed I will support this channel ma'am

[@megh5013]

Thanks a lot Mam for this lecture!!!

[@chinmaykadam1582]

Mam plz cover the topic file handling and after c programming which lanuage are u going teach?

[@anacademy2123]

wonderful way of teaching

[@ankammaraochintala2509]

Thank you for teaching pointer types mam

[@AdityaSharma-ut3hn]

Superb maam thank you so much 😍👌👍👍

[@lingraj8180]

I wish app 10 saal pahle mujhe milti
When I was doing bsc mathematics (honours)....c and c++language ka tension hi nahi hotaa

[@srividyaguttula]

hi ma'am, as pointer contains the address of another variable. so, can we use %x to print values of p instead of %d??

[@hustlewithnik]

Yessss

[@hamnashahbaz372]

Is it necessary to always use null pointer with integer data type?

[@pratikkurra4754]

12:40 can a void pointer be a null pointer as well? @jenny ma'am please clarify

[@vaishnavimishra3904]

ma'am you are the best teacher thank you 🥰

[@chiradeepbhattacharya4858]

Please upload a video on null pointer , and its difference with void and uninitialized pointer jenny maam

[@zishanshams3240]

it's a amazing video for beginner

[@bigcode4you299]

You're very helpful for us dear didi

[@athiragopalakrishnan4316]

Thank you so much for making these videos for us..very useful..you are a good teacher.. Please upload remaining CSE subjects.. Its a kind request🙏

[@nawalkishoryadav1413]

Very nice teaching 😊 very much helping me 🙏🙏 thanks allot from Nepal kathmandu. You 🙏 and family are welcome to Nepal...

[@Olive.grooves]

What is the purpose of using null pointer?
if we don’t initialise a pointer and dereference ,the program will crash but same is the case with null pointer too if we dereference it program will crash then what is the benefit of initialising with null?
Plus I want to tell that I love your lectures n way of teaching ❤

[@kirankumarbarik6965]

Hi mam, can you please teach data structure using Java language..

[@rajanitdep1702]

Mam Iam from Mass , but still I watching your videos . Can I get ❤️

[@abdulrahimjalloh363]

Thanks mam, I really appreciate alot

[@sandipandas4769]

[@user-gv3sm6qc4n]

Thank you mam ❤️🙏

[@ishajain6833]

Thank you so much mam

[@kharatesuraj5952]

mam please explain generic pointer algorithm

[@BTCIV_AyushMalviya]

Thankyou Mam

[@MKO11]

so this means that anytime you have just initialized a pointer it is best to make it null

[@ajaylearningcentre8898]

Superb....mam

[@tirthtanna7771]

mam you are the best

[@leelataddi9940]

Python, java playlists cheyyandi mam plzz

[@preethikmpreethikm890]

Tq mam ❤

[@athiragopalakrishnan4316]

Ma'am please upload Formal language and automata videos

[@shindejayvantbalajirao5957]

Reference books for c, c++ where we can easily

[@baranidharan5349]

int*ptr=NULL , also gives error while printing ptr

[@bikeshjaiswal2704]

Mam plz complete pointer topic fast

[@motiwaledeepak6530]

[@sathishpothakamuri2638]

Thanq for teaching to us mam

[@vivek5807]

Thanks for teaching us mam!!

[@anujkumarrai3949]

Mam pls recurson and next prati se question on recursion pls mammmmmm

[@bitravenugopal8704]

Hlo mam
Please do python lectures
It's exam time 🙄🙄🙏🙏🙏❤️🙏🙏🙏

[@katruramyasri1803]

Mam we can access the value directly...why we use pointers for accessing the value? This pointers occupy some memory...that means we loss some memory in system during program

[@katruramyasri1803]

Yeah! It stores the address but what is the use of that? Mam

[@debojitacharjee]

*BUT IF THE POINTER CONTAINS GARBAGE THEN HOW IF STATEMENT WILL WORK?* - the NULL macro is used to initialize the pointer when we use the if statement to check for pointer == NULL. If we do it the other way like pointer != NULL then we can check the garbage pointer instead without the need to initialize. Or we can initialize inside the if statement only when it's not equal to NULL, which is a garbage variable.

[@ReviewzChronicle]

right

[@pradeeprao2473]

👍

[@sanjanapanwar3844]

❤❤

[@NooglerNafiz]

What is the difference between these two pointers

int* a;
Which syntax is correct ?

[@nagame859]

Both the syntaxes are correct sir!

[@lakshsinghania]

Both are same and u can use both
there is nothing wrong in it

[@a.t7119]
