Read bjarne's book

can you tellme any tutorial sites

can you tellme any tutorial sites

I know only books and prefer them read this one: Programming Principles and Practice Using C++

2nd edition

I know only books and prefer them read this one: Programming Principles and Practice Using C++

ok😊

It's from the inventor of the language

can you tellme any tutorial sites

Most tutorials for C++ have been written by congenital idiots with a screw loose

Most tutorials for C++ have been written by congenital idiots with a screw loose

Lmao

Most tutorials for C++ have been written by congenital idiots with a screw loose

Which is why, only take tutorials written by non-moron individuals with a screw loose

You require to have quite a few mental issues to write C++

Would early return/guard prevent rvo? I am curious about this one

Would early return/guard prevent rvo? I am curious about this one

rvo??

Yes

I didn’t get you

Would early return/guard prevent rvo? I am curious about this one

No

Would early return/guard prevent rvo? I am curious about this one

I don't know but inconsistent discards of return value can

Local variables are limited to the lifetime of the object that created them

I meant local static variables !!

Which is why [[no_discard]] is your friend

I meant local static variables !!

Read my answer on that topic

Doesn't exist function terminate the program without freeing resources?!🤔

No, exit free some resources

Specifically thread local ones, static ones, and those initialized by _start

where to read?

Absolutely not, they have an initialization check and if not initialized they get initialized

Ajay here

?

I could add to that that it means they are not freed at the end of the function

😅😅 Of course not. It shouldn't be allowed. But a clean, croped screenshots should allowed i think.

If we create a copy constructor in a class, does the compiler creates a default constructor for the class?

I read this: When not to use return by address: 1. When returning variables that were declared inside the function or parameters that were passed by value (use return by value) 2. When returning a large struct or class that was passed by reference (use return by reference) Kindly explain the reason for the second point.

so you don't have to use the address-of (&) operator on the reference you were passed.

It's much safer to just return the reference you were passed.

and it will not be copied

I don't think there are many reasons at all to return by address in C++.

there are

fuck pure functions and functional stuff

well, one that comes to my mind would be low-level memory management

^lol

I think it’s okay to return by address if there can be none lol

returning by a reference fields that are not on a heap

What "return by address" means? Return by raw pointer?

I think so

I didn’t get it too

yeah, I think so too.

Since a pointer really is just an address

(A C-Pointer that is)

iirc unique_ptr is just an address too.

Not sure now.

*stored as just an address

What "return by address" means? Return by raw pointer?

Return by a raw pointer via function's parameter list, I guess

@unterumarmung you mean something like "void foo(char** out);" ?

so you return a raw pointer via the parameters?

iirc unique_ptr is just an address too.

Unique ptr contains not only a raw pointer

That seems strange.

I mean: Convert int func(); To void func(int* param);

Or void func(int& param);

ah, I'm not sure he meant that.

I can't guess what he meant

Unique ptr contains not only a raw pointer

It also stores a deleter function since you can provide custom deleter functions for your pointers

Ah, interesting, TIL.

Thanks!

So 2 pointers in total then?

Why pointers?

/get

you can return a value with rvo supported

/rules

instead of passing as a reference and getting a result

One pointer and one function

check out the rvo stuff

I'd assume they'd use a pointer to a fucntion.

No

Callable object is not only a pointer to function

Also lambdas and functors — class objects with overloaded operator()

You can provide your custom types for a deleter function

/get notes

/list

/get names

@Dragon_Trainer786, stop spamming

You can provide your custom types for a deleter function

Ok, thanks!

I want to study complete c++ so I am trying to get notes through rose

Can you help me?
