According to this table, ++a would be evaluated first
then you add a to itself, so
2 + 2
and you add that to a
4 + 1 = 5
BinaryByter
given that addition precedes assignment

Which is better
BinaryByter
which is better?
BinaryByter
wat?
Ariana

Ariana
so it is 6
BinaryByter
dafaq?
Ariana
int a=1
a += ++a + a
a += 2 + a (a=2)
a += 2+2
a += 4
a = 6
BinaryByter
but why assume that a becomes 2 after the second time?
BinaryByter
oh wait
BinaryByter
yea
BinaryByter
makes sense
BinaryByter
i'm stupid
Ariana
well if you never write crippled code you wont need to know 😛
Ludovic 'Archivist'
int a=1
a += ++a + a
a += 2 + a (a=2)
a += 2+2
a += 4
a = 6
or it can start by resolving a
BinaryByter
i never write crippled code
BinaryByter
thats why I don't know

@linuxer4fun so it's ub :P

C++ is hard
BinaryByter
xD
Ariana
int a=1
a += ++a + a
a += 2 + a (a=2)
a += 2+2
a += 4
a = 6
maybe clearer:
mov ebx 1
add ebx 1
mov eax ebx
add eax ebx
add ebx eax
eax is a temporary var and ebx is a

We just added two 3 times. Makes sense

So what about Java? How does it do it?

That's kinda made me comfortable

So what about Java? How does it do it?
The weird thing is
Java and cxx nearly share the same rules in these kind of situations

Hmmm
MᏫᎻᎯᎷᎷᎬᎠ
Java evaluates the left-hand operands
MᏫᎻᎯᎷᎷᎬᎠ
But cxx evaluates the right one

Hello
If i have a multithread app
And add values to a array
Is there any way to make a value not stay more than 5seconds?
MᏫᎻᎯᎷᎷᎬᎠ
SkullzBoy
What do you mean by not stay?
The value inside the array should not stay more than 5econds, it need to get out to a FIFO

ok sorry
Shivang
Can upload a pic book in which i have questions it hard for me to type it
Shivang
Book is c&r
Shivang
K&r
Dima
You can’t understand what the book says?
Dima
yeah you can
Shivang
Shivang
Here the function alloc has the return type pointer to char but in else condition it is returning 0 an int
Is that illegal
Dima
NULL is 0
Dima
simply nothing
Shivang
Ok
Anonymous
Yes it is legal. See it as nullptr

Dima
well I am talking about C
