Why use hexadecimal instead of decimal?

[@engdoretto]

You're a great teacher! Thank you so much!

[@MRKRRNZ]

I decided to relearn C a few days ago and all these videos are so helpful. Just wanted to let you know your work is appreciated even though it’s been a few years.

Thanks for all videos

[@CodeVault]

That's a great suggestion! Will do!

this channel is so underrated

going by this, why ain't octal used instead of hex? is it because hex is a bigger radix and can point to more addresses/numbers than octal with the same number of bits ?

[@CodeVault]

Because registers are usually a multiple of 4 number of bits. Thus you always use whole hexadecimal digits for any value (2 digits for 8 bits, 4 digits for 16 bits etc.). But with octal, you can't do that. For 8 bits you'd need 3 octal digits, but the last one can only go from 0 to 3. This weird rule would make octal clunky to use for memory. But it is actually used for things that have n*3 number of digits (like the permissions in Linux).

Awesome sir

Why the zeros at the left they don't count anyway?

[@CodeVault]

Yeah, it's the same in decimal. 9 or 0009. It's still the value 9.
