1.6 Pointers and 2-D Arrays | Two dimensional Array | Data Structures & Algorithm Tutorials

[@sarojneupane7008]

These (DSA)lecture will be remembered for upcoming 100 yr!! ....best lecture .

[@srijitanitamajumdar5904]

You are literally the Data Structure Queen of KZbin CS Tutorials!! Hands down, to this terrific explanation! Life's beautiful for me again! :D

[@bigk2367]

For anyone wondering, **p gives error because there is nothing to dereference after *p, 'p' is actually pointer to an integer so when you write *p, it returns the value of that first element. On the other hand 'a' gives you the 'pointer to a whole 1d array' and after *a it becomes pointer to an integer meaning the first element of a[0] and then **a finally returns the value at that address meaning 6. So, you can say *p = **a.

I cannot thank you enough ma'am. You just clear all my doubts in this series of data structures.. Before watching this video I thought that I had sufficient knowledge of the 2d array, but after watching it I got to know that I knew very little. Thank you so much ma'am🙏

[@yashkumardhawan6961]

That was so interactive. The concept of pointer and array is now crystal clear to me. Keep up the great work!

Explanation of pointers and 2D arrays ranks right up there with the late Lord Harsha's and Animesh's mycodeschool tutorial. Well done, Jenny. Jenny, Abdul Bari and mycodeschool are great instructors.

[@abdulrahimjalloh363]

Madam Jenny, you are the best, I learnt C from your videos, and now Data Structure. You are far better than many lecturers.

[@TheDev05]

I came here after getting some confusion in my *online* college lectures, but trust me....every and each point is crystal clear now.

If listened carefully, the explanation was complete and was depicting your knowledge about this ,which is awesome . Thank you mam.

[@freakstechnology8018]

After watching this lecture i can say that I have clarified many things in this concept of array and pointer. Thanks a lot mam ✌️

[@durgeshkumari4231]

ma'am i had so many doubts in pointer and 2D array that's why i had seen many videos but they didnt clarify my doubts. Surprisngly , i saw ur video on it and now they help me a lot in understanding the basic concepts of it 🔥🔥 .Thnks ma'am. Keep going 🤟🤟🤟

[@Harshmishra-mj7zf]

The best thing about your lecture is that u don't use compiler to teach so it actually allows me to use my imagination 🔥🔥

[@vedangkavathiya8426]

Answer of **a and *p both will be 6... Nice explanation:) If we write **p then it is error...

[@ravindrakumarkushwaha1564]

yes if we write **p then error if we write **a then 1

[@er.waseem8695]

@@ravindrakumarkushwaha1564 in case of **a its going to print 6

[@gokulraj9566]

bro can explain **p why is error

[@dhruvvashishth3122]

@@gokulraj9566 because p stores the address of a[0][0] which is 100 .*p is value at address 100 which is 6 and then **p is value stored at address 6 ,which is not an address, hence error.

The output of both expressions :- **a and **p will be 6. and thankyou for this complete explanation. :)

p is not a double pointer and therefore it gives an error.

Mam you are very beautiful.....and you are a great teacher......great respect.......mam you are doing great job......I paid lot of money in my college ....but I don't get this type of quality education there....because teachers are unenthusiastic and they don't value there job...thank you mam....you are doing great help to India's student

At first I thought you concepts would not be very very sharp but after seeing this pointer in 2d explanation which maximum number of good teachers fail to explain properly you explained very correct and very nicely 👍👍💯

your explanation made me think for you. thank you so much ma'am .

[@monirzaman5366]

Value at **a: 1; In this version, a is declared as a pointer to an array of 2 integers. So, when you dereference a once (*a), you get a pointer to the first row of the 2D array. When you dereference it twice (**a), you access the value at the first element of the first row.

[@justcurious1940]

**a == 6 ?

[@sugarboo104]

@@justcurious1940 I think it's 1

[@justcurious1940]

Ma'am your explanation is very awesome And your last line is very is relief I will see you in next video till then bye bye take care

[@djay00009]

For **p , it is better to write int (*p)[3] and then p = a. Then **p will give 6 as the output as well.

I will print **p it will occur error on compiler time

Yeah, I should probably watch all your tutorials instead of going to class. I actually learned more from here

[@manish-mk]

**a=6 But **p will be compilation error. Because p is not a double pointer. Also p has base address of array which in this case is 100. So then it would be like **100 *100 will return value 6 But after that *6 will show error because we can't dereference any value. We can only dereference address.

[@Nikita-hv5jm]

If so then a also holds the base address of the array. So *a should give the value stored in a and also **a should give compilation error right

[@rounak3239]

@@Nikita-hv5jm ur argument is also right then what is the correct answer.

[@debosmitachatterjee1096]

@@Nikita-hv5jm no, a holds the base address of 2d array , and it contains 3 1d array so a = a[0] and when *a=*a[0] i.e 100 , so **a=*100=6

[@jaijaijaijai123]

I think @17:10 there is a mistake. In place of 'a' we can't write p, because p is of the type (int*) while 'a' is address pointing to int[3]. a+i= &A[i] i.e address of ith row. But p+i will take i integers ahead of A[0][0] and point to its address i.e &A[0][0] +i.
