❤️

Also guys what do you think about epoch in C++, personally for me it's very exiting feature?

Valid until 2038:)?

Valid until 2038:)?

you think it is not possible to implement with 23 standard?

Nah I thought about date epochs, nevermind

I have shared link above)

I think it is revolution changes in language

of course if it will be implemented;)

I think it is revolution changes in language

It will not be a revolution. I see it as a natural evolution instead, if the people will be intelligent enough

Pattern matching in 23❤️

Pattern matching in 23❤️

what is that?

Modular std Epochs

I think I miss this feature

what is that?

Read about it It's like a switch statement level 99999998

you think it is not possible to implement with 23 standard?

everything is possible to implement, even now. c++ is turing complete

Most of the paradigms in C++ is a Turing complete even generic

Read about it It's like a switch statement level 99999998

also i dont think you can compare pattern matching to a switch statement, as a switch statement is pretty much nothing else than a table where to jump to

ahahah this code looks to crazy:))

And pattern matching Is an automatic table that is made from diamond and steel

wat

I'm creating a priority queue of pair<int,string> which stores the elements based on the value of int and if they are equal then compare the string

Here is the code: `` class cmp { public: bool operator()(pair<int, string> &x, pair<int, string> &y) { if (x.first != y.first) return x.first < y.first; return x.second < y.second; } }; priority_queue< pair<int,string>, vector<pair<int,string>>, cmp> q; q.push({1, "coding"}); q.push({2, "love"}); q.push({2, "i"}); q.push({1, "leetcode"}); while(!q.empty()){ pair<int,string> p = q.top(); q.pop(); cout<<p.second<<endl; } ``

Output: love i leetcode coding

Why is "love" and "i" coming first in the output

My comparator should put the element first which has smaller int and if that clashes then put the smaller string(lexicographically) first

Hey does anyone know to properly interface a c++ program with Arduino via serial communication?? I have done it but it is not accurate the tx and rx pins blink when am sending data through the serial port but most of the time the Arduino doesn't do anything I programmed it to do!!

do you use correct band?

Yes!

Got it

why I didn't find on the internet the bubble sort algorithm fully optimized like this? I implemented it but everywhere it's half-optimized, this should be fully optimized isn't it?

the problem with this optimization is that if we have for example an array long 1000 and the last half [500-999] is already sorted, this algorithm will still check if it's sorted, ye? instead with mine I put a wall where the last swap has taken place and I check all before that, am I right?

Guys I need a little help, I have a couple of static libraries that I want to merge into one static library. I have write add_library(name STATIC) and then target_link_libraries(name ....). But new library doesn't created

What I am missing?

Guys I need a little help, I have a couple of static libraries that I want to merge into one static library. I have write add_library(name STATIC) and then target_link_libraries(name ....). But new library doesn't created

What the hell ? Just create a new lib file and move code from other libs into the new.

Sir

What the hell ? Just create a new lib file and move code from other libs into the new.

I don't think that will work for me

As I understood target_link_libraries doesn't link library immediately into .a file.

For example if I call from some top level Cmake with add_executable(some) then I write target_link_libraries(some mylib) and Cmake for mylib was the next add_library(mylib sources...) target_link_libraries(mylib libs)

So this libs will be linked into some executable not into mylib

Am I right?

Thanks Rose

Hi, I'm new to WPF, and this question really bugs me. While there is TableBindingSource and TableAdapter in WinForm, why is there no TableBindingSource in WPF? It makes thing difficult when I could do it easier with TableBindingSource.MoveFirst, etc. Is there any particular reason? Thanks.

You are starting with c++ and wpf? whew... you should know a lot about it before using it

Hi. One doubt, I do not understand anything, in the case id_produtor [0,1,2 ...] the id_cons is always 3 and should alternate between 0 and 3. While in the case of consumer cases the id_cons prints well, SOMEONE KNOW?

Ligne 39

Should print between 0 and 3 for the for that is on line 19

Pls help .... I can't understand prims algorithm of shortest path using c language. .... Pls some one help me...🙏🏻🙏🏻🙏🏻🙏🏻

We cannot take your brain and make it understand this. Just ask some questions about the topic. We shall answer.

Someone can help me?

I saw the question

It is written in French Variable names etc...

No, in spanish

So It's hard for me to understand what's going on

No, in spanish

See... yeah I don't know 😂

😂

If u want translate it, or ask a more specific question

Ligne 51 alwais print me 3

Pls help .... I can't understand prims algorithm of shortest path using c language. .... Pls some one help me...🙏🏻🙏🏻🙏🏻🙏🏻

First understand the concept( like on paper and pen ) and after that see different implementations in C

I don't know why. cout << "ID CONSUMIDOR ----->" << id_cons << endl;

Alright

Why id_cons is always 3 ?!

https://pastebin.com/Ssf4tCGc

First of all, you use the variable i twice in doubled loops. Lines 14 and 19.

Rather you use two different variables. i and j, for instance.

True ...

I tried to understand the code but no luck...i hope someone helps u

https://pastebin.com/MX3mYpQz

I fixed it but the bug remain. In ligne 7 print well but in 27 not!

What is wrong in line 27?

Alwais print 3 number, and need to alternate from 0 to 3

In ligne 39 print well the "ID_CONSUMIDOR"
