How to return and pass a struct to a function

The difference between C and other languages is quite obscure even if the syntax is the same.

What a fantastic lecturer! Always straight to the point (and to the subtlest and most important ones!). Your explanations are always cleanly compiled.

Finally understand why so many library functions ask for a pointer for result instead of using a return value.

This is a really worthwhile and best video on returning the structs!

I really hope you get more subscribers man, your video are by far the best when it comes to c programming.

I'm from the 80's and your video is really awesome how you expose through levels the right use of pointers in a "healthly" way. Thanks for sharing!!.

That was simple amazing. Step by step, explaining the thought process at each one of them, until reaching the perfect code... Thanks!!

[GIGEO]

Excellent and on point explanation. Thank you.

Mastering C feels like learning some sort of arcane magic...

[sanjoy]

Thanks bro.... you just cleared my confusion about C++ and C# about the default function calling type

[Sarahhh]

Thank you so much for this, you are truly great!

[OZtheVillain]

This was such a great video, I really learned a lot. Thank you so much!

You are such a good instructor! Thanks!

[dabunnisher]

Fantastic videos. Your instruction is very good.

[vaibhavnayak]

bcuz of your videos i am starting to understand and like C. Thank you.

the fact that he doesnt look at notes or script shows me how well he knows his stuff in contrast to others

[figiegi]

thank you man
Keep up the good work!!

Hi, Nice vídeo, Very easy to understand, thank you.

Very well explained, better than I tend to do 😅 In my old job we had interns that I always had to teach to stop returning a value like it is done in Pascal or Java.
And I was very confused to find out that in college they didn’t learn that arguments go on the stack. That a stack pointer just moved back up when you exit and indeed if you had another thread running the stack could’ve been changed. We had that happen.
And ironically those Java, Python and pascal people hate seeing a pointer being passed to home a result. That’s a foreign concept to them. And that’s why I am a firm proponent of at least having students code in assembly for the first semester. Even on a simple 8 bit micro doesn’t need to be very complex.
Just to really understand how memory is used.

How come we are able at 6:37, this works? We are trying to access a variable that got popped from the stack, for example if the function returned int*, and we tried to access that array that got allocated in the stack, we would even get a warning because we are trying to return the address of a local variable.
