- In this tutorial I explain the meaning of the argc and argv variables that are often passed in the main function of a C or C++ program.
Want to learn C++? I highly recommend this book amzn.to/1PftaSt

Argc is ARGument Count and and argv is ARGument Vector.
And "Vector reffers to an array, not a C++ or Euclidean vector"
See reference here:

is he managing directory by programming ?
what are counts and vectors in C?
@@makara2711 I tried to print the argv it shows the path of some designated file
I want this guy to explain literally everything in my life
I couldn't understand this for so long, I read some stack overflow, watched some tutorials, looked up some problems and nothing helped until I found this video, great explanation!! Feels way better to finally understand this
Never understood it until I saw you video 👌👍
Hey Paul, I'd like you to thank for putting your energy into making this tutorial. It was really enlightening and it made me comprehend the concept much better. Keep up the awesome job.
You CAN declare a variable inside a for loop in C. Just use C99 or C11.
@Artem Katerynych It's a standard that the compilers have to follow. it's not a version
@Artem Katerynych Well technically we're both late.
@@nicolareiman9687 yes
@@nicolareiman9687 it is a version, if you define it to be "[a] particular form or variation of an earlier or original type" (American Heritage Dictionary, 5th Edition). It's not a version of a particular C implementation -- such as a compiler or standard library -- but it is a version of the C language.
Edit: And I'm also a year late, lol.
i was about to. To be honest i dont get why ppl dont use c99. I just dont get it. If anyone can explain i will apreciate it alot
This scared me in the past to start with c++, but it's actually such a simple concept.
Thx Paul.
I recall Jullian Assange saying, "commitment requires sacrifice, courage is contageous". (The latter meaning if you surround yourself w/ your peers, courage is contageous).
This said, while learning to code, (we're ALWAYS students however), we forget previous lessons etc, the "commitment" part is, constantly reviewing what we may forget.
This said, THANK YOU for your great work here on UA-cam.
Cheers

You are literally the best my professor expected most of us to know c and it took me about 2 weeks on an assignment because i couldn't figure this out but bc of u i have been able to solve the task on the assignment. Thank u.
This is the clearest explanation I have ever seen on this particular item !
Man, you are amazing! You really know what you're doing. Please, don't stop!!!
Quite a lucid explanation. Thanks Paul for making such an awesome video. You've gained a subscriber.
Awesome video! I'm brazilian and I want you to know that your video are healping people from all around the world! Thank you very much!
I have been searching so much for this, even my book doesn't explain what is this, thx a lot
I remember being so intimidated by this when I started learning C++. But then I learned that I didn't need it at all and I forgot about it completely.
so do i have to learn this or what bro i am a cs student who are a completely beginner :)
@@ibrahimozmen9668 unless you are building commandline applications for Linux or old terminal based systems, you don't need to worry about it.
@@mistakenmeme thanks bro. I just wanted to learn how it works
This video was so helpful with understanding my embedded systems homework. Your video really clears some things up. Thanks so much!

Thanks for the explanation, God bless you!!!
Thanks works fine. Greetings from Italy
so clear and excellent explanation.
Just to mention that the arguments must have a space or TAB between them and not a ; or ,
good explanation. well understood. thanks man
Great explanation, Thank you so much!
Thank you so much! Very clear explanation.
You explained this way better than my teacher.
i always declare variables in for loops in c
Did you make a C programming tutorial? You explanations are so clear
always provide notes to things you have spoken makes us understand better okay 👍
thank u so much for your efforts
love from india
You are just amazing bro, thank you so much, you helped me a lot!
Thanks, this has confused me and I have it on my exam. You cleared it up :)
Really helpful, thanks!

many thanks for sharing your knowledge
subbed
Thanks it is very well explained
Great, thanks for the explanation!
Thank you very much! This is well explained! :)
best video explaining this! thank you
Bro holy shit. I misunderstood arg c and argv when i first heard it. But god damn now i finally know how to use it. Thank you so much
great explanation
understood in one go...
Mindblowing! First I wondered what it was in Java, then in C# and now I finally got the answer in C++ :)
it's actually C
@@frogsam4228 it's identical in this case
@@adamodimattia Idk tbh bcz I know nothing about c++
but I'm sure that the format of main itself is different also the standard library is iostream right?
so I guess they can't be identical right
@@frogsam4228 it is, but also in C++ you can use everyting what is in C, all the C libs too
@@adamodimattia ooh I didn't know that
thanks a lot
fantastic explanation!
Thank you this helped me a lot!
great explanation
Thank you. Pretty decent explanation.
Thanks super clear explanation !
Great explanation, most of the university professors can't explain this.
how did you get your program to run in the bash or command prompt? I created/ran it with console app and I can't write ./add 3 2 5 or anything to it.
Great tutorial!
Well and clear explanationn...
Thanks so much dude，it really helps me in terms of my final...
Wonderful explanation! Thanks.
I have only seen
The way I understand it
- int main(int argc, char* argv[]) is like saying
data_type array_name[]
-int main(int argc, char* argv)
This one takes a string called argv instead of an array. Since string is declared as char* string
- int main( int argc, char **argv) uses a pointer concept
Check this www.programiz.com/c-programming/c-pointers
Great explanation, thx!
Thank you for this video
My friend, in C you can declare "int i=0" in the for loop. Wish you the best!
Alexandru Dinu yes, but that variable would be deleted as soon as the for loop finishes!
@@ledues3336 Can you please explain a bit more? or point to the right source? Because CS50 does the same as Alexandru mention above.
@@ledues3336 Yes, this is the intent.
Real savior!!!! Thank you!!!!
This was awesome!
I'm new in porgramming and this video show me for what is this argc and argv. But for what need argc to count his own call from the elter process?
Subscribed! Thank you! :D
gut geklärt!
Thanks to share!
Thank you. Your teaching had a very clear progression from basic code to more complex code.
Thank you, from Turkey.
Thanks for the explanation I get it, but why is it required? What happens in the background process?
very very good video helped a lot thanks dude :)
