Using Pointers to Print 2D Arrays

[@imMortAlDA2]

Literally u cleared all my confusion within 4 minutes. Clear explanation 👌

[@fidalgoverde]

That's why C is the most beautiful language of all.

[@musaibmuneer1907]

I second that

[@tayyab.sheikh]

Only when you have beautiful teachers to explain you. ❤ from 🇵🇰

[@HopeNHopes]

I won't be that sure :))))

[@utkarshmalviya9458]

Happy Teacher's Day Sir, Thank you for being such a great teacher.

[@bimalmurali2781]

you are great sir!! very good explanation..

[@lokeshnegi5051]

really good voice quality

[@mostafalabib8609]

you have cleared my all confusions in just four minits, which I couldn't in 4 hours.

[@soumi6720]

I WANT TO THANK THIS CHANNEL AND TEACHERS SO MUCH ESPECIALLY YOU SIR!

[@prathaptalari3583]

Superb explanation sir❤️❤️❤️❤️

[@080_cse_sanjaykarthicks4]

I love this and because of new concepts like this, I am starting to love C as same as I love Python, which is the easiest programming language.

[@tayyab.sheikh]

It's easy just because of his amazing teaching method.

[@iqdotcode706]

Wow C is really great

[@tomaszstanislawski457]

The address `&a[0][0]` points to a first element of the first row of the array. The row's type is `int[2]`. Therefore according C standard this program is undefined for anything because pointer arithmeticsis only allowed within a single array. `&a[0][0]+2` is fine for comparison while `&a[0][0]+3]` will invoke Undefined Behavior.

[@Kim-rh9gt]

thank you bro , I've learned a lot from this channel

[@qandos-nour]

Great but maybe is not useful when we want to print array in row column format it will print it in one row

[@dubstepbanane6277]

You can add a and check when to print that

[@HopeNHopes]

Love from Iran🇮🇷❤

[@mustafatarig5412]

0:33 *n rows , not n-1 rows

[@livenow1656]

Superbbb🔥🔥

[@NivaethanRudraharan]

Great and helpful

[@sudhanshukaul1350]

Respect+++ for this guy

[@skdkdmdmsjdjdj2377]

Finally we found a purpose for pointers

[@carlossantamaria1820]

so in 2d arrays when we pass the 2d array as argument to a function, we pass the base address as well right?

[@sukhbeersingh5811]

Yes

[@musicalvibes9541]

Very good explaination

[@trueresources3847]

how are 2D arrays stored in c++??? row major or column major??

[@greenxdshadow6635]

row major, he said it in the video

[@soumiksaha1595]

Thanks Sir, So much helpful!!!

[@patricioemilianomoralesdia7578]

I totally agree

[@AbhishekV-t8f]

Can someone please tell me what the time complexity is for the pointer based approach? Is it O(n) or O(n^2) Thank you

[@jeethendra374]

its o(n)

[@serendipityx737]

you saved my life

[@venkateshpolisetty5624]

Sir, you told the array name itself holds the base address of the first element of the array. Then what is the need of '&' in front of a[0][0] in the for loop?

[@krishnachaitanyareddygujju2823]

array name holds the base address, therefore we use " a " not "a[0][0]"; a[0][0] is a value not address; &a[0][0] is address in for loop you can use this, "for(p = *a ; p < *(a+row); p++)" or "for(p=&a[0][0];p

[@krishnachaitanyareddygujju2823]

@@nivasreddy yes, in this case we can do it in two ways 1)int a[2][2]; 2)int a[ ][2]; Both will do just fine

[@aProudHinduatani]

Just awesome 👌👌👌

[@pallavi_10]

Well explained sir thank you so much🤗

[@shrutikabagul2886]

Very helpful video Thank you so much

[@marbles5590]

I made some code similar to yours because the first one (merely following the code shown in the video) showed an error after compiling. So this is the modified one: #include int main() { int rows, cols; printf ("Enter row: "); scanf ("%d", &rows); printf ("Enter column: "); scanf ("%d", &cols); int arr[rows][cols]; printf ("Enter %d numbers: ", rows*cols); int i, j; for (i=0; i

[@m.anharmunir615]

thanks bro!

[@taibohere]

I have anomaly? When we have *p pointer then it's value will be printed And when we have simple p the address will be printed am I right??

[@sanctuary_of_soul]

You have pretty nice accent, thanks for that. And of course THANKS for the video: it is very useful.

[@nilanjankar4522]

In this case, we can't change the line after printing a row. Am I right?

[@georger844]

You can use an if statement i guess

[@carlossantamaria1820]

@@georger844 how?

[@MKSundaram]

Can I access the array index number instead of value using a pointer? If yes, how?

[@pranaylambat9743]

Is This playlist includes data structures or not? ...

[@albinsanthosh8697]

tahks bro

[@pranaylambat9743]

Data structures???

[@nikolaiunger6932]

best teacher ever

[@akshayrathod1591]

Sir how should i get the remaining video playlist of data structure? please tell me procedure.

[@shabeerkhan379]

Great@

[@cezzar5233]

Int p , h; P = &h; P in this case is a pointer, am i right? I mean it is not a normal variable anymore?

[@handle_gc]

p is int variable P is not defined If you wanna declare P as pointer use * while declaring int *P=&h; or int *P; P=&h;

[@jagdeepsingh-tv4ty]

anyone please ! int *ptr; for(ptr=&a[0][0][0] ; ptr

[@goumuk]

You can understand this using one dimensional array itself. if array length is 5 for example, you will write for loop condition as for(ptr=&arr[0]; ptr

[@nj10018]

Answer= **(*(a+1)+1)

[@bytecodeskool]

Sir please upload more and more videos and please complete the playlist I have exam please sir

[@Yuvapriya-zx1jg]

Sir it doesn't print all values 1,2,3,4 it prints only 3 and 4

[@lateefwani2676]

Sir if i join neso academy... Can I get videos other than uploaded by you...?????????????

[@sumitgothankar6021]

c++ tutorials please

[@esbatu13]

That can't run on c++ why ?

[@esbatu13]

#include using namespace std; int main() { int A [3][3]; cout *i ; } for (int a = 0; a

[@abhiavinash5164]

I'm getting error while I.m initilizing p=a in for loop instead of p=&a[0][0]... sir u said, arr name can be use as pointer and it points to 1st elements, then y its not working for 2D

[@ritikshrivastava9442]

Same doubt brother

[@iamgroot20]

Can someone write program for it

1,2,1,3,2,5,3,7, this series is a mixture of two series all the the odd terms in this series form a fibonacci series and all the the even erms form the prime numbers in ascending order.write a program o find nth term in the series. I want easy explanation n coding of this question sir

[@1012ube]

did you just say even prime numbers?
