It will be much better. aint it?

That depends on the task, but if you need to find key-value pairs, map or set looks better

but it is like building an apartment with a hammer and some woods

It depends on specific situation. The problem I faced is a already-built online search engine (in C++), and a required to-be-built debug system, which is bind closely to the existed search engine. In this situation, building the debug system (web interface) with C++ is very natural, since every message required by the debug system is internal state of the search engine, and thus could be extracted easily with the engine itself.

Hi, im learning threads in C++

But im seeing that pthread isnt available to windows..

I have found the pthread-win32, may you have some documentation?

that this is for windows

Somebody there?

I have found the pthread-win32, may you have some documentation?

Use std::thread, not pthread

Wich librarie contain it?

Wich librarie contain it?

Standard one

ohh ok...

ohh ok...

Google for it

I found it

Do you have some good book?

about this topic?

about this topic?

cppreference.com is good enough

ohh documentation...

Thanks bro...

Doesn't multimap provide the use of [] operator?

Read manual, everything is in it!

Can anyone help me with error flag

In c programming

#meta

i and iii are correct. But will Copy const be called if an object is passed by reference as a parameter to a function?

Yes

So all three?

III is not correct

II is not correct

Base obj1 = ob2 //constuctor is called

Base obj1 = ob2 //constuctor is called

Yes

so i alone?

Maybe your test is old and III is aslo correct

But now it is not

i and iii are correct. But will Copy const be called if an object is passed by reference as a parameter to a function?

actually I can't understand the last option

what is an object returning from a function

it means we are using reference to that object?

i and iii are correct. But will Copy const be called if an object is passed by reference as a parameter to a function?

No, will not

after deleting one pointer initialised by another pointer, we can't access both the memory location right? both P and Q becomes dangling pointers ?

No, will not

so i and iii, per se?

so i and iii, per se?

Yes, but (iii) has a special condition. If RVO is not used, the constructor will be called. If RVO is used, constractor call can be omitted. So, in (iii) a constractors MAY BE called, not ARE CALLED.

you can access it, you are not right.

yes , becomes dangling.

you can access it, you are not right.

You can access the memory but this is UB.

yes , becomes dangling.

We can access. But it will refer to some random value?

You can access the memory but this is UB.

Ok

We can access. But it will refer to some random value?

No, it's UB.

Got it👍

actually I can't understand the last option

Why are you sending this? You either study or make yourself self-check. Listening like others answer is useless

I try not to send pics often. Wasn't able to interpret the third option. So had to send.

It's not the Q of pics...

Okay👍

1 and 3

III is not correct

[n]rvo you mean? It is rather limited. In general copy/move is performed

Just have noticed move wasn't mentioned

98 test than, 1 and 3 the answer
