Hello everyone. I have two questions. 1. Does anyone know telegram chats about embedded programming? 2. Can someone say something good or bad about book "Reusable Firmware Development"?

I found a piece of code assigning reference to its own. What are the reasons behind? auto &val = map[key]; val.first = xxx; map[key] = val; Why don't we do it in this way: map[key].first = xxx;

Since you have a Russian name, I can suggest you to look for chats you need here: @it_chats — this is a collection of chats about programming, mostly Russian speaking

how declare tree in c

restrict is not Cxx and hence it does not compile / not iso conform

Hi Sunday and welcome

You're welcome

Help !! There's seriously frustrating-illogical problem happening with my code, in this part (line 188 of attached code): sort(_fam_size_order.begin(), _fam_size_order.end(), [&_fam_costs, &inverted](int a, int b){ return inverted?(_fam_costs[a]>_fam_costs[b]):(_fam_costs[a] < _fam_costs[b]); }); Program runs as expected but if I change greater/less than signs to <= and >= , program doesn't run at all. No Compilation error, No runtime warning - It just doesn't print anything at all !!! Using mingw-64 on windows 10. Compile command : g++ -lpthread -Wl,--no-as-needed -static-libstdc++ -static-libgcc .\santa_workshop\dt.cpp -o .\santa_workshop\dt.exe -Wall For sidenote : Currently, I'm saving output to file, but it doesn't print anything on console as well. Here's the code : https://pastebin.com/Fzk4BRew

in java we use chartat() to find character at index position. but how to do in c?

What is int main(void) in c

What is int main(void) in c

my buddy google can help ya with that

int main can define the entrypoint of your application it may differ based on your usecase though

Yes but what the process it will do

I searched but still not understood

why not just type it out and compile it :P

But how to explain it in examination

break down the code and write out the local variables and try and figure out what they are doing when they interact

isnt he just lazy to do his homework?

i'll give you a hint, the question isnt really about any calculation in there, but about the way formatting works
