Parra

use this construction:

Parra

#ifdef __cplusplus extern "C" { #endif // declarations #ifdef __cplusplus } #endif

Parra

you have here the example:

So it goes directly into the code? Rather than being called on like somewhat a header file would

maybe the c code already uses that kind of constructions so you can directly include it

Parra

if it does not use it

Parra

then you have to wrap the include like this:

Parra

#ifdef __cplusplus extern "C" { #endif #include <your_c_code.h> #ifdef __cplusplus } #endif

Parra

if that header already uses this construction then you can include it directly without anything extra

CM

Guys any idea why this program is not compiling

CM

When i compile and run it always giving me info that your program not compiled

Kat

Well actuate Windows or install Linux first of all

Kat

Second of all, try a different compiler

CM

Second of all, try a different compiler

Thanks i managed to run the program

Any one here can difrentiate between. Function overloading and function Overriding. ??

Any one here can difrentiate between. Function overloading and function Overriding. ??

If a class has multiple functions with same name but different params, it's known as function overloading

If a subclass provides a specific implementation of a method that is already provided by its parent class,it is called as function overriding

Also if you haven't heard about Google. Please check it out. It's made especially for peeps like you.

Idea for addition to the C++ standard: template<class T> class lockable_data { T& operator->(); T& operator*(); void lock(); void unlock(); }; the idea is to group a mutex and some data into a single class

BinaryByter

what do you guys think?

Dima

this is not intuitive

BinaryByter

How not so?

Dima

mhh

BinaryByter

It would, on the other hand, reduce the amount of helper classes needed in threading

BinaryByter

or of global variables

MᏫᎻᎯᎷᎷᎬᎠ

what do you guys think?

I would tell you

Dima

std::string goes = "skraaah";

BinaryByter

True, atomic does that

BinaryByter

?

BinaryByter

This isnt the same ^^

BinaryByter

this isnt always locked

BinaryByter

this is

BinaryByter

same as with mutex

BinaryByter

advised use would be in a lock guard

Ludovic 'Archivist'

Same as with mutex, locking more than once per thread is a noop

BinaryByter

are you a mitbuster?

Mits

Thank u @MissRose_bot n no I m not @linuxer4fun 😅

BinaryByter

pretty much, yes

BinaryByter

Thank u @MissRose_bot n no I m not @linuxer4fun 😅

xD

BinaryByter

or just lock_guard, since its templated

Ludovic 'Archivist'

Mutexes use the thread_id for locking so that a thread cannot self-deadlock

Mits

xD

😄

BinaryByter

Mutexes use the thread_id for locking so that a thread cannot self-deadlock

How does that affect this?

Ludovic 'Archivist'

How does that affect this?

Imagine you call a function on locked data that attempts to lock the data again

BinaryByter

Well then you'd have a noop

BinaryByter

as you said earlier

BinaryByter

But lock_data doesnt care

BinaryByter

since it just wraps a mutex

Ludovic 'Archivist'

Mutexes use the thread_id for locking so that a thread cannot self-deadlock

And that is how it is implemented

BinaryByter

Oh okay

MᏫᎻᎯᎷᎷᎬᎠ

Ludo won this round lol

BinaryByter

Wat?

MᏫᎻᎯᎷᎷᎬᎠ

Nothing

BinaryByter

Lol

BinaryByter

So in overall, do you deem lockable_data to be a good idea?

Ludovic 'Archivist'

no

Ludovic 'Archivist'

hwo do you swap two lockable data ?

BinaryByter

hwo do you swap two lockable data ?

You dont

BinaryByter

Or you wait until both are unlocked

Ludovic 'Archivist'

Or you wait until both are unlocked

You understand that you make a structure that is prone to making people do deadlocks?

BinaryByter

You understand that you make a structure that is prone to making people do deadlocks?

Nice :D

BinaryByter

You dont

lets stick with that then

Mits

Can't I send any link?

Dima

I will take a look

Dima

no, you cant send that

Dima

Mits

Oh k.. thank u 😊

Mits

😂😅

Has anyone solved *NPTEL assignment c++*

Guys I have a question . Well I searched many times how to create 3D objects in c++ and got this

Anonymous

but how to make it realistic like this ?

well do you know any source or any guide for this ?

I know only some OpenGL
