I think you can skip the reading of class Strumento. Also, the negozio.h is something already given like this, not written by me but by my professor

Can you send error again?

🐉

I'll write it here

Anonymous

Yep

🐉

negozio.cpp:82:19: error: no declaration matches 'const Strumento& Strumento::operator const' const Strumento & Strumento::operator const

There are no symbols after "operator" in the actual compiler error?

🐉

seems so

Actually I dunno what error is

Try to change getPrezzo return type to just float

Anonymous

const& for float doesn't make sense anyways

🐉

This is the second time I hear this thing about float not needing const

🐉

But Still dunno why

Anonymous

Because const& is used to avoid unnecessary expensive copies Copying of float is not expensive and const& can ruin some advanced compiler optimizations

🐉

Oh that's why

🐉

Hey man, could it be that I got wrong the Snipset of negozio.cpp

🐉

Noticed it now

Hello everyone. Can you create a timer and stop it when entering a specific option, and if I don't stop it, another specific command will be executed and I want the method please. I just finished the c ++ course

You can create for sure We won't do it for you

🐉

I think he's just asking if it's possible

I don't want it, I just want a hint😁

👌🏻👌🏻

🐉

I'm not quite sure if it's possible, I know there is a library related to time

Anonymous

Use std::thread

🐉

Ctime maybe?

@

I made the timer, but I can't control it

Anonymous

Ctime maybe?

No, don't use C if there's a good option in C++

@

Use std::thread

Thank you pro ✌🏻

It's not a valid question anyways

🐉

The timer should be a difference from the start until the stop

@

Yup

@

I will try thank u

🐉

like start at 18:37:06 ends 18:38:09 and then the difference between them, probably there is some function in <chrono> library

🐉

We could help if you send us your code maybe

Yep You just can store start time point, then store end time point and then substract them

@

I will try it

🐉

Maybe for an easier approch ctime would be better

No, it is not

using namespace std::chrono; start_time = high_resolution_clock::now(); ... end_time = high_resolution_clock::now(); auto time_in_ms = duration_cast<millisecons>(end_time - start_time);
