Thank ma'm, actually I'm finding why we return 0 in main function,now i understand..🤗

[@denno445]

Very clear and simple. Great video

[@Log2Base2]

Thanks a lot. Happy Learning!

[@muhammadfarooqkhan5569]

thanks, I found my answer here of using 'int' with main() instead of void after many reading c++ many years.

[@AlmukhtarA]

Thanks a lot, you make very easy.

[@unique_ruler_memes3003]

Mam, if the program returns integer value then we use int main..but my question is how can I know that the program will returns integer value..(in hello world there is no integer).

[@Hustle_kiing]

0 means true,1 means false here,not like only integer value👍

[@44r0n-9]

Technically the OS invokes the _start wrapper function, which subsequently calls the main function.

[@rodie99999]

Yes. And I think learning English properly should also be one of the top priorities.

[@Python-FPV]

Log2base2 I have a question
If there is some error then the program won't compile at first place. If program is syntactically and logically correct then program will run anyway. What's the point of writing return 0 then ?

yeah bro this also my question have you understand now please tell me..........

if prog could return non zero to os upon any error if it encounters, then why can't it send zero automatically without explicit mentioning

[@brennanb3919]

Thank you!!!

[@adlakrishabhm4018]

Thanks ma'am !!

[@shubhambhandari4647]

Mam why can't we use any other integer in the return 0; statement ....I meant to say that can we use return 12; return 5; or any other integer in the place of return 0 cause 12, 5, etc. are also an integer ......Hope you can reply soon I need desperate help.

[@rodie99999]

0 is the standard value returned to the computer to signify that the program has executed successfully.

[@oogway5472]

You can.I wrote return -456 and the program executed successfully..

[@srchzo]

Thank you ma'am

If i buy a course can i use it lifetime for free?

[@artabinkabir2908]

If we use " return 1 " statement in main function and there we also have some errors while it was executing or running then it will a non-zero value. What will happen in the meantime?

[@artabinkabir2908]

If the program be okey then it will execute to " return 1"
Why 1 is for problem
and 0 is for okey ?

[@adarshrathi4038]

but after compile without return 0 ans is given so why use return 0

[@Rahul-zo2rz]

same question. If the program worked, it'll automatically return 0. Why should we manually give a statement to return 0? I wish they explained that...

What is the intention of we using conio. H

[@abhishekm1903]

Hello Mam....
I have one question....
int main(int argc,char *argv[ ])
What is the Role of Argument count & Argument vector??

[@Log2Base2]

Hi Abhishek,
Like we pass an argument to any function. We can also pass arguments to the main function while running the program.
Like below,
./a.out hello world
These are taken as strings(space separated).
In this case, the main function int main(int argc,char *argv[ ]) will receive 3 string arguments.
So the value argc will be 3.
And argv[0] will have "./a.out"
argv[1] will have "hello"
agrv[2] will have "world"
These are known as command-line arguments in C.
Hope you understand the role argc & argv.
Thank you!

[@nirajraut9408]

@@Log2Base2 The "stdio.h" header file contains the function's official prototype also called as "function declaration" and not "function definition" as you said. The function definition is typically present in the "stdio.lib" folder.

[@Log2Base2]

@@nirajraut9408 Yes. That's why we have said stdio.h has the necessary information to include i/o related functions. Function definition won't present in the header file. If the statement presents anywhere in the video, kindly point out the video duration where it presents.

How return 0 is optional.... sometimes it is not written then also the compiling works how 🤔 🧐

[@PhucTran-ex5ut]

If you dont explicit return statement in mại function . it will return default value 0

here android development course?

[@shubhambhandari4647]

and another thing why doesn't void have a return function

[@rodie99999]

void itself means empty. It doesn't have a return type. So no values are returned.
