it will show you exactly that it is fine
klimi
And the sites that keeps popping you up with notifications
Anonymous
But it has nothing to do with anonymous
it is an anonymous function as the union has no name
BinaryByter
like a real comrad would

tell him to share his porn
It was not certainly porn it was that kind of stuff Lucy wants to meat with you and boobs pic

The problem is, in a union at most one element can be active at a time, correct?
you can only read from 1 element at a time yes
Anonymous
or write to only one

olli
you can only read from 1 element at a time yes
C++ only allows you to read the element you wrote to, expect they share an initial sequence
olli
u32 and u8 don't share an initial sequence
olli
You wrote to u8 , so u8 is active
Anonymous
? it is uint8_t *
olli
Reading from u32 is UB
Anonymous
with 4

it is uint8_t u8[4];
Anonymous
this is an array of size 4
Anonymous
the sizes match
Anonymous
the size of this union is still 4 bytes

if he did not have the [4] i would agree
