you can use such operators to store flags

srry

std::swap (a, b);

is this a c++ function?

anybody?

is this a c++ function?

yes

defined in <utility>

Hi all guys

I am a noob and I have confuse ideas

It's possibile to point a value store in an array?

pointer to value in your array?

int b,c; void g(int a) { int c; { int a,d; } }

Hi everyone For the block in which a and d are declared, which parameters and variables are visible?

/warn ad

Hi everyone For the block in which a and d are declared, which parameters and variables are visible?

all of them but a shadows the prior a

all of them but a shadows the prior a

Which are priority then ?

I think a as global, c as local variable. Is this correct ? But I am confused about a

Sorry I wrote the wrong question. b is global, c and d are local variables

outside scope nothing is visible

global are visible everywhere

pointer to value in your array?

Yes fill the pointer with array's value in a loop (its not matter the type of loop)

Yes fill the pointer with array's value in a loop (its not matter the type of loop)

int* a = nullptr for (…. i++) if (array[i] == …) a = &array[i];

like that?

assuming it is array of ints

Aaaaaaaaaa

Is necessary the &?

yes because you have a pointer and value and you point to that value

WHY DO YOU HAVE TO CLICK THESE BUTTONS

its corrupted can't open

its damaged.pls make sure its okay

Hi. Does anyone know how can a set be iterated if it's implemented as a red-black tree? Is a Binary search required everytime you increase the iterator? Or is there some sort of array of pointers keeping track of the actual order?

Wrong input 🙏

I don't understand this type of error

Endian

Yes

I don't understand this type of error

Try to cast addresses to unsigned int

unsigned long int in case of x64

I don't understand this type of error

but in any case (if i remember true) result of expression is k++, the expression before is useless

Mmm

d is my pointer

a and b are arrays

I would to point the sum of the sum of the array's value for each step

I'm feeling confuse :D

sure, but & has lower priority

So Confuse damn c++

So [] is the first and then you will get address of a[k] item

And addresses can't be used in + expression directly

So it's necessary to cast it

but *(&a[k] + 1) is Ok, in this case you'll get value of a[k+1]

but don't do that :)

thank you for help

but what is the meaning of cast?

i believe that i must study the sintax better

syntax

but what is the meaning of cast?

It's just a workaround of nonsense operation) if you will do something like "address1 + address2" you will get a new address which (99.9%) will be inaccessible)

mm ok

but i would the value not the address of value

just a[k] + b[k])

Easy)

yes but give me the same error

i'll post now

What is type of "a"?

int

Is it an array?

yes

Post all code please

aaaaaaaaaaa no

it isnt an array

:D

my shitty mind

All is ok) it happens)

yauuuu it works
