What you guys do when after long time without coding you forgots some of the concepts and syntaxes?

true... humans do forget

thank you so much :)

Why drivers and kennels are written in C rather in C++?

But any reason for this preference

Hi

linux liked C, and those at windows... idk

I have aquestion

Hello, go ahead

But any reason for this preference

He says C++ is a terrible language

It is his right

In c++ the address of pointer is the address of the variable that the pointer point on it?

Professionals know if they want to make something extraordinary they have to use C++ not C

No different

I wonder how'd you make 3D games using an egine that runs on C

Professionals know if they want to make something extraordinary they have to use C++ not C

Well, linux kernel is extraordinary thing written in C

No different

Thank you

Joke's on you

if you say so ¯\_(ツ)_/¯

you are just stupid, i dont want to talk to you more

Well, linux kernel is extraordinary thing written in C

Extraordinary is that it supports C++

Am too lazy to do that thanks btw

In c++ the address of pointer is the address of the variable that the pointer point on it?

There no address of pointer term in C++

There no address of pointer term in C++

I think he means the address of the pointer where it's pointing too And the variable pointer

I think he means the address of the pointer where it's pointing too And the variable pointer

Yes

In c++ the address of pointer is the address of the variable that the pointer point on it?

The address of the pointer variable location in the memory Term is pointer to pointer

p1 points to v P2 points to p1 that's it

what will the output? int x; x = sizeof('a'); printf("%d", x); the output is 4 but it should be 1

according to ISO 9899, 'a', 'aa', ... are integer constants. I'm not aware of C++ due to ostream char

Why we don't we write while defining linked-list struct node { Int data; node *next; } Instead of.. struct node { Int data; struct node *next; }

according to C, you may not define a struct like that.

Hello...I want to learn windows programming using win32 API using c ..does anyone hear have a good book(pdf)for a beginner?.

You want to learn c language

what will the output? int x; x = sizeof('a'); printf("%d", x); the output is 4 but it should be 1

In C symbol literals have type int

according to C, you may not define a struct like that.

Ok

Hi needs help. I have to make a program in CBuilder where must extract the files and subcarpetases with an API function.

@Neko_cpp wtf is this ? :D

why not

why not

Idk, promo ? 🤔

5 elements and 5 inputs to the array. and sum of em getting ok. but when i tried to output average, it’s always 0. anyone please ?

how we can use b = B(i); at line 22 and a.b.show() on line 30

How can I thread-safely return a small array from a function? I'd rather not dynamically always allocate memory, because the function is going to be called very often, so I'd like it to be as performant as possible.

Pure C

Is it a constant array?

what is the problem?

What will be assigned into var b

Hi needs help. I have to make a program in CBuilder where must extract the files and subcarpetases with an API function.

What will be assigned into var b

b = B(10);

Is it a constant array?

No, it is not.

b = B(10);

Is it equivalent to b = 10

create a local array, and pass it (of course by pointer) to the function

That's actually a very nice idea, thank you.

Is it equivalent to b = 10

no. b.b == 10. b itself is an object of type B. learn the basics of OOP

Okay thanks.

hello, guys. yesterday I watched a video tutorial how to make a simple keylogger. i got the idea and tried to code it on my own however something with the code doesnt seem to be okay. it should log all the pressed keys in the output file yet there is only '1' i also tried to change the code a bit.. eventually got some other number but it is not what the program is supposed to do. please have a look

thats not the whole code

#include <iostream> #include <Windows.h> #include <fstream> that is what is not in the screenshot. sorry.

yes

okay

you sure that getting the keypresses works?

yes, each key i press while the program is running gets its asci printed in the console. even mouseclicks

it just doesnt get written in the output file. instead it only writes '1'
