Nice video i learnt perfectly through edureka

[@nathankidd7595]

Thanks a ton for your help. BTW in the word "array" the emphasis is on the second syllable, "uh RAY."

[@edurekaIN]

Hey Natham thank you for watching our video. We will definitely keep this in mind :)

[@emmanuelamoh7181]

This was really helpful man! I understand how to work with arrays now!

[@manikantavaddepalli1597]

Nice explanation thank you

[@thelasttimeitookashowerwas7069]

Great tutorial+love the fact that you reply to every comments.Also i wad wondering why num's been used here and what exactly is the value of num and to what maximum point does this loop go upto

[@edurekaIN]

Hey Suman! Yes, we try to remain connected with our viewers. Thank you for acknowledging it. To answer your query: 'num' is used to set a limit to your loop. Over here, your loop is limited to 10 iterations so, the value of num is 10. The lop has a maximum of 10 iterations. Hope you find this useful as well. Cheers :)

12:42 how can accessing a value in memory out of range of array size corrupt a memory ?

[@edurekaIN]

Hey Sharad, thanks for checking out the tutorial! With regard to your query, please go through the below given example: int i; int arr[3]; int main(void) { for(i=0;i

[@GirlGoesWhoopWhoop]

Hi, I'm unsure as to why when you pass the array through the function you don't need to initialise the variable num? Where does num get its value from?

[@edurekaIN]

Hi, thanks for checking out our tutorial. When passing an array to a function, we just pass the array name. Array name points to the base address of the array. The function gets the value of the array from that base address. Hope this helps. Cheers!

[@nooramieranatashawizan2873]

can we just use int a[ ] instead of int arr[ ] in the subprogram of largest number ?

[@edurekaIN]

+Mighanut mya, thanks for checking out our tutorial! Yes, you can use any other name, and even your name. The only limitation is that the name should not be a keyword(reserve language word) and few other. But there are some rules that are followed while naming variable and the most important one is that the names should be intuitive.But there are a lot of variabe naming conventions that people follow, you can even create your own naming convention. Compiler stores these variable names in symbol table and this symbol table is used during run time for name to memory mapping. The compiler may even discard name provided by you totally and use it's own name internally in symbol table. That is how function overloading works in C++. So, a or arr is all for your ease. Use what suits you better. Here arr gives you a hint that arr variable by name looks like an array. Hope this helps. Cheers!

[@kaiochanx3348]

what is system("PAUSE") and what does it do?

[@edurekaIN]

+KaiochanX3, thanks for checking out our tutorial! System("pause") runs the Windows command-line "pause" program and waits for that to terminate before it continues execution of the program - the console window stays open so you can read the output. Hope this helps. Cheers!

[@kaiochanx3348]

+edureka! Oh right, thanks for the information, great video

[@ciphergates5596]

hello sir, i am not able to understand that, the variable b is of int type then why it will take 4 bytes as you explained above.

[@edurekaIN]

Hey, thanks for checking out the tutorial! With regar to your query, the variable b is of type int, but it is an array so the size of the array will be (size of int) * (size of the array)= (4*5)=20 bytes. Hope this helps.

[@ciphergates5596]

GOT IT. THANKYOU

[@SharadGaur0609]

for 16-bit compiler needs 2 bytes memory and for 32-bit compiler int need 4 bytes memory. 16-bit compiler ==>> Turbo C 32-bit Compiler ==>> GCC or Visual Studio is this what you were asking (why 4 bytes and why not 2 bytes) ?

[@ciphergates5596]

Thankyou .

[@edurekaIN]

Hey Sharad, thanks for checking out the tutorial! With regard to your query, it depends on the platform. It is implementation-defined. It can be 2, 4 or something else. It can be 2 bytes then there doesn't comes the use of 32-bit to increase the size of int it is upgraded to 32-bit. Could you please elaborate on your query to help us support you better? Cheers!

[@sameerpal2474]

int take 2byte memory. not 4byte¿¿¿

[@edurekaIN]

Hey Sameer, thanks for checking out our tutorial! The size of an int is really compiler dependent. Back in the day, when processors were 16 bit, an int was 2 bytes. Nowadays, it's most often 4 bytes on a 32 bits system or 8 bytes on 64 bits system. Still, using sizeof(int) is the best way to get the size of an integer for the specific system the program is executed on. Hope this helps. Cheers!

[@surajpai104]

do you have java video lectures

[@edurekaIN]

Hey Suraj, thanks for checking out the tutorial! Here's the link to the Java tutorial playlist: kzbin.info/aero/PL9ooVrP1hQOFR25JoQW3h3n5pBs77e6KU. Cheers! :)

[@bharatshankar5]

why u write system("pause"); please explain clearly

[@edurekaIN]

Hey Bharat, thanks for checking out the tutorial! About your query, system("PAUSE") is used to stop the terminal from exiting quickly before you can see the results. If you use system("PAUSE"), the console window stays open so that you can read the output. Hope this helps.

[@surajpai104]

why have you intialized a[10]=0

[@edurekaIN]

Hey Suraj, thanks for checking out the tutorial! The statement a[10] = {0} ; at the beginning of the main() initializes all the elements of array a to 0 so that none of the entries contain garbage values. Hope this answers your query. Cheers!
