You're right (If I read correct)

I am right if I wrote right.

that means compiler first flushes the previous cout output stored in buffer and then cout further outputs if any and then again clears the buffer when program ends.

that means it is good practice to use flush ? right? 🤔

clearing buffer free the storage, I think.

Not really

Buffer is static array

So size of empty or full are the same in real projects

that means it is good practice to use flush ? right? 🤔

It's a bad practice to use flush for no reason. There is a reason why cout has a buffer. Flushing means it needs to do a system call and print. That's slow. You want to do it as little as possible.

okay

A buffer flush is the transfer of computer data from a temporary storage area to the computer’s permanent memory. For instance, if we make any changes in a file, the changes we see on one computer screen are stored temporarily in a buffer. Usually, a temporary file comes into existence when we open any word document and is automatically destroyed when we close our main file. Thus when we save our work, the changes that we’ve made to our document since the last time we saved it are flushed from the buffer to permanent storage on the hard disk.

i also tried g++ -L <PathToBoostLibFolder> reg.cxx ... but didn't work { gave me undifined refrence to error

How can i get a new software arduino C++?

Is there any one who is expert in solving c language questions??? Please dm me 🙏🙏

Actually I need help in c questions

Why DM?

Just ask

Can I send u the ques ??

Send here the question, what you have tried and what's not working

How can i get a new software arduino C++?

What do you mean?

How can we take specific formatted input in c++?

how to define a variable length array without Dynamic memory allocation in C++ ?

Can anyone tell from where to install mingw

Can anyone tell from where to install mingw

look up msys2 mingw in google and you'll find it

The supplier generator thread. The argument is a pointer to * the shared Simulation object.

supplierGenerator(void* arg) {. } How do i make this arg point directly and be able to manipulate a class called Simulation in c++?

Anyone?

supplierGenerator(void* arg) {. } How do i make this arg point directly and be able to manipulate a class called Simulation in c++?

What's the problem?

Pass a pointer to the class if I understood ur question

What's the problem?

i tried doing Simulation* sim = reinterpret_cast<Simulation*>(arg); but i get segfault repeatedly

i tried doing Simulation* sim = reinterpret_cast<Simulation*>(arg); but i get segfault repeatedly

The casting is ok. Probably bad pointer

what do you mean by bad pointer?

Or something beyond that which u r doin wrong

oh i see

what do you mean by bad pointer?

You don't point to the object

i also tried Simulation* sim = (Simulation*)(arg);

What?

because simulation is explicitly constructed

class Simulation { public: TaskQueue supplierTasks; TaskQueue customerTasks; EStore store; int maxTasks; int numSuppliers; int numCustomers; explicit Simulation(bool useFineMode) : store(useFineMode) { } };

Where is the object?

class Simulation { public: TaskQueue supplierTasks; TaskQueue customerTasks; EStore store; int maxTasks; int numSuppliers; int numCustomers; explicit Simulation(bool useFineMode) : store(useFineMode) { } };

this

And where do u pass it

this

Not what I asked u

in my function called suppliergenerator

I didn't ask where is the definition of the object.

in my function called suppliergenerator

What? Isn't it the one with the void pointer?

yes it is

I didn't ask where is the definition of the object.

what did you mean?

Wtf? Lol. I'm asking where do u create the object.

Wtf? Lol. I'm asking where do u create the object.

as i said i create the object in the void function called suppliergenerator, isn’t that what you meant?

as i said i create the object in the void function called suppliergenerator, isn’t that what you meant?

Nope. It's not created there. You want to pass a pointer of the object to that function, no?

Nope. It's not created there. You want to pass a pointer of the object to that function, no?

Yes i want the arg pointer in my function i.e suppliergenerator(*arg) to point to the simulation object

Yes i want the arg pointer in my function i.e suppliergenerator(*arg) to point to the simulation object

Yes, so where is the simulation object created?

Nope. It's not created there. You want to pass a pointer of the object to that function, no?

the simulation object is created in a file called requestGenerator.cpp which creates and enqueues information into a taskQueue

“ Use a SupplierRequestGenerator to generate and enqueue * requests.”

the simulation object is created in a file called requestGenerator.cpp which creates and enqueues information into a taskQueue

Good. Show how u pass it

enqueueTasks(int maxTasks, EStore* store) { taskCount = 0; while (taskCount < maxTasks || maxTasks < 0) { taskQueue->enqueue(generateTask(store)); printf("%s", "enquing occurs"); taskCount++; sthread_sleep(0, 100000000); } }

the store and max taskargument in requestGenerator.cpp are from the Simulation object

and theres another file called taskqueue as well

I don't see where u pass it here to supplierGenerator

I don't even see the object creation here.

SupplierRequestGenerator:: SupplierRequestGenerator(TaskQueue* queue) : RequestGenerator(queue) { } Task SupplierRequestGenerator:: generateTask(EStore* store) { …… }

the generate task has so many different things that the supplier should do (hence the …)

SupplierRequestGenerator mySupplier(&sim->supplierTasks);

this is how we pass it if the object was called sim in the first file

supplierTasks is a Simulation object?

yes

it is a queue defined in another file

Explain

class Simulation { public: TaskQueue supplierTasks; TaskQueue customerTasks; EStore store; int maxTasks; int numSuppliers; int numCustomers; explicit Simulation(bool useFineMode) : store(useFineMode) { } };

Is it this object??

I have a file called taskqueue which is supposed to concurrently handle customer request and supplier requests. This task queue is in the simulation object as taskqueue supplier task and task quque custoemr tasks

Is it this object??

yes

So under sim there is a Simulation object called supplierTasks?

exactly

Show it

Where do you define "Simulation* supplierTasks"

Or "Simuation supplierTasks"

Where do you define "Simulation* supplierTasks"

you already saw it in the simulation object

No

U said it was the Simulation Object
