so learn everything yourself

best way ever

nobody ever taught me whats lambda and how it looks like so KEK

Lies What about the docs ?

Docs learnt us all

I mean about colleges and another stuff

docs for the win

Docs is the master teacher

docs for the win

Sure folk

ok.. anyone prefers that void Get(Object& out) over that Object Get()

?

I think or the first one is efficient (I am not talking about rvo and stuff)

sorry this sticker send by her self

i am new in this app

hhhh

i am sorry

i try to change it hhhh

ok.. anyone prefers that void Get(Object& out) over that Object Get()

I know modern compilers support RVO but am just curious

ok.. anyone prefers that void Get(Object& out) over that Object Get()

What does Get do? If you need a function, different from the constructor, to setup your object I would expect that function to instantiate it as well. Due to rvo the performance might not differ at all

returns local temporary variable

Object Get() { return Object(); } vs Object obj; Get(obj); void Get(Object& out) { /* work with out there */ }

So in the second case you would be required to write Object o; Get(o); ?

yes, am curious whats more efficient to use

or its basically the same if RVO is supported

If the compiler performs RVO the performance might be the same

However, is it not possible to perform the get functionality inside your constructor? (In case you are only creating the temporary object to perform the get Operation) So would only need to write Object o;

I have something with string manipulations like String cpuName; and calling some platform-depend stuff like cpuName = Platform::GetCpuName.. and so on

its example

which you tuber channel is best for learning c ?? plz tell me frnds

How to solve this problem

Easy

How to solve this problem

How can you learn something if you ask other to do your learning ?

CODEBLOCKS isn't installing in my lappy Can anyone please help

yeah, 1. download any linux distro 2. install it and remove windows 3. use gnu compiler collection

Is socket buffer a circular buffer? Is the buffer in single direction?

depends on socket implementation I guess :D

Happy Independence Day, 4th of July for US People.

How to solve this problem

even/odd with modulo-operator %. the other things with compare-operators <=/>=. Combine them with &&. print with printf

How can you learn something if you ask other to do your learning ?

Ok thanks for suggestion

depends on socket implementation I guess :D

Is there a way to achieve bi-directional with the same socket at the same time?

That means receive and send at the same time

Bi-directional?

Use 2 sockets

And 2 threads

That means receive and send at the same time

simple socket is like that, it can both receive and send

It will be async tho

ok.. anyone prefers that void Get(Object& out) over that Object Get()

if you need performances, the first for sure

Nvm

Use 1 socket and 2 threads

if you need performances, the first for sure

Even with rvo enabled?

Use 1 socket and 2 threads

Let me try it out. Get to dive into socket-related manual

Even with rvo enabled?

it always depends with what type of data are you working. if you works with big structures, reference is faster, otherwise value

hmmm yeah I do work with large objects

ok.. anyone prefers that void Get(Object& out) over that Object Get()

First is same as Object& Get()

Without ref you always make a copy in cpp

i need high parallelism performances with big tensors. with value, i lost more time by coping data than do the calculations

ok.. anyone prefers that void Get(Object& out) over that Object Get()

The second one makes a copy

First is same as Object& Get()

also this is an option, same result

Without ref you always make a copy in cpp

But that’s what rvo is about, it does not create a copy

Return Value Optimization

mm

Most compilers support that

is it built in to some compilers?

oh

didnt know that

The best way is just to use compiler Explorer an see for yourself

Done

🤙🤙🤙 Thanks

First is same as Object& Get()

Out of curiosity, how would you implement this function?

Return the value normally

Let's say you have Object mObject in class

Object& Get() { return mObject; } This will return a reference to the member object mObject

okay, I see But then it differs from void Get(Object &) since the class would be the owner of the object

How come?

The 2 ways are identical
