This is maybe the most important lecture of the whole C course... Thanks a lot for this great explanation!

[@hetaeramancer]

no, most important is the fiorst couple of videos

[@Dalia2Lily]

NESO Academy, I can't stop loving you guys

[@motivationmastery2327]

Noone could have ever taught this as much as clear as you did!Salaam Rocky bhai!!! Love you 3000!

[@sayaknandi139]

You guys are really good teacher and i m telling from my heart u made my programming concept more clear...For your videos i do not need a private tuitor..Thanks a lot

[@axolet]

Roses are red Violets are blue Neso's the best tutor for you

[@pradhanan9413]

Doesn't rhyme but its true❤️

[@prototype18]

You guys are seriously doing a good job Thank you Neso Academy!!! Keep up the good work!!!

[@azubuikedanielezeadim4019]

Oh my God! since i have being having problem with pointers, this is the first channel that gave me a better, clear and gently explaination, not even my prof

[@SerhatAtes]

int (*p)[5] = &a; -> below printf outputs are the same because base address of first element of the array and base address of the whole array are the same; printf("%p", p); printf("%p", *p); printf("%p", a); printf("%p", &a);

[@Trading_Club007]

yes its correct whats the problem

[@yesvee7377]

Please make a course, I'll pay you to signup for it, from my heart i saying this, the example and visualization you gave for pointer to array was not even in the books, hatsoff for your wonderful wonderful work. This country needs more teachers like you guys in IITs and IIM's

how to print other elements ???

[@manthanparekh6490]

Please also explain for 2D array

[@ganeshraj541]

why we are not same ampersand in two-dimensional array? For example: in one d array: (*p)[5]=&a; but in two d (*p)[5]=a; what is the difference?

[@tayyab.sheikh]

Amazing ❤

[@mohankrishna2875]

Very nice explanation sir 🙂

[@Aabara_ka_dabara]

informative lecture....

[@prajnasuresh2876]

*p is not a pointer, it's the value to which 'p' is pointing(*p is de-referencing the value precisely) whereas p is a pointer. correct me if I am wrong?! we are usually confused reading *p as a pointer, well but it's not!!

[@compilerrun5516]

When the address of first element and the whole array is same then why do we need to put "&a" instead of "a" ?

[@anhminhnguyen4522]

Because by default "a" is the pointer to only the first element (or sub-dimensional array) of the "a" array not the whole array itself, this shall have further implications when we move on to more advanced C techniques. That's why we use "&a" instead. If you stick with his intuition regarding the operation of "*" and "&" operator you can interpret "&a" as "coming out of the first element's memory block to get the general address of the whole array"

[@user-vp2mf2pw1m]

how can we use sizeof() function to get the size of "the whole array" using this "pointer that points the whole array"? I was trying to get length of array by somehow getting the sizeof("the whole array pointer")/sizeof(array[0]) can we do so without using for loops?

[@MohamedMagdy-pt5zo]

Thx for your help

[@akshaycharjan6384]

Thank You Sir :)

[@satyamsharma5181]

Sir can u make a separate video on how to pass the entire array to any function and to return it back to main() And how to declare these type of array

[@abdullahrahad3584]

hello bro have you solve your problem?

[@crazyboy-gw7rk]

Same

[@Thetejano1987]

I understand the concept of it and how to use it but I do not understand why it is must be declared as int (*p)[5]. Can you please explain?

[@tejastej2762]

Superb

[@qandos-nour]

thank you

[@indian3451]

Plz make a video on DMA

[@animeshsrivastava5067]

int (*p)[5] = a; should be done , instead of using &a

[@adityasaxena6619]

int a[5] ={1,2,3,4,5}; int (*p)[5]= &a; int (*p)[5] =a; if we replace line 2 by line 3 still output remains same.Why so??

[@krishnachaitanyareddygujju2823]

&a : address of whole array a : address of the first element of the given 1-d array; this can also be written as &(*a) coming to your question; in this context a and &a are equal because when we store address we store the base address here base address of a and &a are same. but however ; a and &a are very different.

[@hetaeramancer]

what if i've written *p[6] or *p[4] for that matter? whereas the array has 5 elements.

[@tomaszstanislawski457]

it would not compile because `int[6]` and `int[5]` are not compatible types

[@ase6817]

why can we just leave out the & and write int*p=a instead of int*=&a or int*p=&a[0]

[@nileshpokale862]

Enemy down. All cleared.

[@adityaraje7015]

Can pointer be stored in array if yes please give me syntax

[@mca_waala]

Nice

[@EverythingTechWithMustafa]

Sir notes plzz

[@devToumeh]

thx but how to call the second value ?? withoud adding ++ i mean *p[1]

[@swapnilprantamistry]

Hi there, what will happen for these statements? int arr[5] = { 1, 2, 3, 4, 5 }; int *ptr = arr; for(int i=0; i

[@harmankaur3938]

here *ptr is pointer of first element of the array 'arr' so according to the for loop condition, ptr means the pointer (containing the address of element) will get pre incremented and post incremented, and after that the value will be contained. thankyou

[@user-vn9ld2ce1s]

Well, someone should've told us this a long time ago...

[@adolfocarrillo248]

So "a" is equal to a pointer to an integer because "*(&a)" is the same as "a" right?

[@shabeerkhan379]

Suppose the length of array contains 10 elements.is it possible to point a pointer only 5 elements in those array??

[@AjeetKumar-he9lk]

No, if you have got an 1D array of 10 elements. By putting * and &, we are transitioning dimensions (shown as boxes) and not half or full of an array. But also... Yes, if you talk about a 2D array of 10 elements (i.e. two 1D array of size 5). For that: int a[2][5]; int (*p)[2][5]=&a; // &a is for whole array So, p is pointer to whole array *p is pointer to 1st 1D array which is of 5 elements (voila, got it!)

[@behindthescene4406]

@@AjeetKumar-he9lk bro I didn't get how &a is pointed pointed by (*p)[5] ...I mean how 5 elements pointing to &a ....they must be individually pointed by array of pointers ...plz some clear tis doubt

[@syedyousufhussain2725]

what if i want to print second element of array

[@SerhatAtes]

*(*p + 1)

[@nickolaisimmons4638]

First 57 seconds better at explaining that most other videos lol

[@Hiyori___]

ok so if we do printf( "%p", p ); and printf( "%p",*p ); we get the same result as an hexadecimal value because it's an address
