speachless!! you are soooo goood in explainging. thanks a lot

[John-slzz]

your style of pedagogy has helped me in overcoming phobia of coding.
the sort of knowledge you are imparting is enriching our lives.
thanx a ton & we look forward to having more such amazing content.
kudos to you.

[devugoel]

This was the best. Saw many tutorials, but understood the concept here in one go. I rarely comment on videos, but really had to appreciate you here. Thanks man!

[WistrelChianti]

Brilliant! I particularly liked the repetition when driving home a particularly important point. Superb work (and exactly what I was looking for - was searching for a good detailed explanation on structure storage in memory).

[andresvallelisboa]

Thank you very much! I understood it. I Love the format you chose for the video, a black background, a representation of the memory bytes and everything was explained in a very direct and simple way.

[anshhmehta]

Perfect video to understand the importance of padding and its uses.

[michaelhernandez]

trying to read how this works is way harder than having pictures and someone explaining. Thank you.

[sunilkumarreddy]

Sir it is a good class for me. Thank you sir, upto now I didn't no the background allocation of memory now I got clarified. SIR ONE MORE THING, I WANT TO sll, dll, cll, sporting techniques tree's, graphs, bss. Pls... upload sir, one of ur student, thank you sir.

[manoharbompella]

Explained very detailed, Cleared every doubt.
Thank you

when declaring a char and then a double variable it should give 4+8=12 as output. But it shows 16. Can someone explain why?

[sujitsatpute]

You are explaining 💯 times better than my college

[dono]

Padding is not defined in the C (or C++) standard. This behavior depends on the compiler. It can also be configured too. For example, VC++ has the /Zp and #pragma pack options while GCC has -fpack-struct option.

[ArjanvanVught]

Missing to explain __attribute__((packed)) with unaligned memory access which is possible (with ARM).

[andistheinforitbutso]

Awesome work 👏
Lesson: we should be careful while arranging the srruct variables for better memory utilisation

[vipulchawla]

If we use one int, one double and again one int variable then the size of variable should be 16 but it is 24 why???

[manuelconte]

It is a good habit to put first the biggest type in ascending order to help compilator !

[beeyou]

I m having 8 yrs of experience. Noone Clarified the doubt lk u..thank you..expecting more content from you

[umairalvi]

Considering the processor is of 32-bit
Void main ()
{ char a;
}
then in the memory for the variable a, only 1 byte will be allocated, then how the processor will request this memory using word...without padding?

[VivekYadav-dsoz]

Why is the compiler not allowed to rearrange member variables? If there's a consistent rule for this, then even external libraries will not face any ambiguity. That way, int variable could've been placed in front, and no wastage will be required and all 3 can be accessed in one CPU cycle.

[TechnoVisionTV]

Such an amazing explanation! You made it so simple to understand, thank you :)
