oh, ok

so within a same program i have to create 5 threads one for each philosopher

howe mach I am tride It does not work you can help to write this code?

what if it is not a light weight process?

#include <iostream> int main() { int N; std::cin >> N; const int arr =1000; for( int i = 0; i < N; i++){ std::cin >> arr[i]; } for ( int i = 0; i< N; i++){ std::cout << arr [i] << " "; } }

i mean in any certain condition

Write a program that gets a natural number N (N ≤ 1000) at the input, then a sequence of whole N elements. As a result, the program must display the sequence in reverse order. Use array to solve the problem

#include <iostream> int main() { int N; std::cin >> N; int arr[1000]; for( int i = 0; i < N; i++){ std::cin >> arr[i]; } for ( int i = N-1; i>= 0; i--){ std::cout << arr [i] << " "; } }

@lightness_races_in_orbit can you directly share me the code for Dining Philosopher's problem, it is not my homework I promise I need it because by referring that code it will help me in understanding the whole concept and also help me in understanding other problems such as "sleeping barber", "reader-writer", etc..

oh ok

any source (link)?

every tutorial is explaining pseudocode

#include <iostream> int main() { int N; std::cin >> N; int arr[1000]; for( int i = 0; i < N; i++){ std::cin >> arr[i]; } for ( int i = N-1; i>= 0; i--){ std::cout << arr [i] << " "; } }

you are very kind thank you so much

Can anybody help me with std::forward? I have a little trouble: why when I pass const reference to std::forward it deduce it to just const type whithout reference? Meanwhile without const all works fine. MyClass myClass; // simple structure with couple variables MyClass& class_ref = myClass; std::forward<MyClass&>(class_ref); // all is ok const MyClass& class_const_ref = myClass; std::forward<const MyClass&>(class_const_ref); // no instance of overloaded function "std::forward" matches the argument list: (const MyClass)

Hey guys, i am looking for somebody who have strong knowledge of algorithms to have a small chat?

guys is there any assembly dedicated telegram group? or can we just ask here?

guys is there any assembly dedicated telegram group? or can we just ask here?

maybe this will help you: https://t.me/assemblybr

but assembly here is kinda allowed too

* C/C++ discussion preffered (assembly also allowed), asking about other languages (or groups for other languages) right after joining will get you BANNED.

maybe this will help you: https://t.me/assemblybr

wonderful, thank you very much

void foo(const MyClass& class){ bar(class); } void baz(const MyClass& class){ } template <typename... Args> void bar(Args&&... args) { baz(std::forward<Args>(args)...); }

but assembly here is kinda allowed too

i will eventually ask here when I'll be banging my head on the assembly inline project we have to do

Thanks for the answer. So far, I have not been able to reproduce the behavior of the program from real code. A little later I will prepare it.

Yeah, this code works. But in my full version static analyzer give me this error

what if in this function only "void philosopher" was written instead of "void* philosopher"?

what is the return type of void* func(statement) ?

pointer of any type(expect you will cast it)

can you elaborate a little?

Who knows gtk?!

I found the video, pls tell me what you think. c++ and beyond atomics part 2, see minute 30:52 https://channel9.msdn.com/Shows/Going+Deep/Cpp-and-Beyond-2012-Herb-Sutter-atomic-Weapons-2-of-2

Try to comment strings of code, idk what else to do :D

Hello, in this code I could not how (rand() » 10) & 0x01 works and gives binary elements for data[i]. Same thing for data_int. I cannot understand how is it working. May someone help me about it. for (i=0; i<k; i++) data[i] = (rand()>>10) & 0x01; /* convert data[] to integer data_int = 0; for (i=0; i<k; i++) data_int = (data_int << 1) ^ data[i];

some_integer & 0x01 gives either 0 or 1. >> 10 is useless here

some_integer & 0x01 gives either 0 or 1. >> 10 is useless here

Thanks, I got. May you help how the second loop works.

It writes all bits from array into a single integer variable preserving bit order

I assume k is sizeof(data_int) * CHAR_BITS

I assume k is sizeof(data_int) * CHAR_BITS

Thank you for the help.

Is it possible that the same C code on one machine works and on the other doesn't?

Is it possible that the same C code on one machine works and on the other doesn't?

Yes

depends. usually when you're seeing this type of behavior there's a memory problem. aka pointer

It's called undefined behavior

if you're running Linux install valgrind from the repository and run your app under valgrind

depends. usually when you're seeing this type of behavior there's a memory problem. aka pointer

A pointer is a memory problem.. Lol!

Yes

how is it possible? i compile the code

there seems to be a lot of confusion here of what a pointer is

It's called undefined behavior

I've already told you

How it's possible

how is it possible? i compile the code

compiling doesn't mean that it's run time correct it just means that it's syntactically correct

compiling doesn't mean that it's run time correct it just means that it's syntactically correct

OK, but we try to use some standard code indeed

not sure what that means

not sure what that means

how can you write c code that works for all machines?

stick with the standards but you're not understanding that compiling code successfully doesn't mean runtime correct

stick with the standards but you're not understanding that compiling code successfully doesn't mean runtime correct

are there any particular flags on gcc for this ?. I understand what you say, but the code compiles and outputs the expected values.

and what happens on the other machine where you say it doesn't work

multiple definition in global value

is the definition in one of your header files

is the definition in one of your header files

in the header file i define global value and in .c file i write extern myvalue

is that header file included in more than .c or .cpp where is that her file included in another header file

is that header file included in more than .c or .cpp where is that her file included in another header file

in c. file i use incluce myheader and in h. file use #ifndef LIB_main_H #define LIB_main_H

what is the global value but you're defining

what is the global value but you're defining

uint8_t *dump_sigma;

you might want to post the code so we can have a quick look

Hi first. Am last

like what more can be possibly see this year

this year is a fuckin' nightmare

damn this is probably the deadliest attack in twitter's history

almost half of the silicon valley's top dudes just got hacked

thats what happens when ppl hungry

Hi I'm using a structure and it looks like this typedef struct{ int id; char name[30]; } User; int main( void ){ User* user; user = (User*)malloc(30*sizeof(User)); free(user); user = NULL; return 0; }

I would like to know if the space reserved for the name is also released when releasing the pointer
