it was so easy tried everything but this was most easy to understand

[the_Alchemist]

I have a doubt.. after allocating the double, the index occupies till the 15th index and when we start allocating the integer ..why can't we allocate it at 4, index 4 was free nothing has at index 4 reply True or False for my approach
We are taking from the 16th index because it is in contagious memory Location so that it will continue forward not backwards?

I was trying to learn structure padding everywhere on the internet but after watching these 4 videos now my concept is cleared. Thank you so much sir you explained the concept so well. Please upload more videos like this. Thank You again!

Here character c whole word will be accessed.
Also rule 2 holds good
Both concepts are correct

Very informative video . Thanks geeks for Geeks Team

[Odo_ela_sabil_rabek]

this example means that system works as 64 bit machine? True Or False And Why?

[adityachhawal]

i think its totally depends on how we assign variable to the struct
if we just change the alignment of the assign variable then the size will gona definitely change
and do you want to comments on the long long and long datatype variable
i reallly wanaa to know..:)
Thanks ..(^_^)

Can you check this code in 32 bit target, double variable after char will start at offset +4, we can verify by offsetof macro, so we can correct rule as alignment as per word size, not by size of type (especially double it differs)
