A funny story happened to me this week. I'm not a fan of complex templates but decided to write a bitset class that can be parameterized with a enum (so I can use enum values as bit flags).
And to top of that, I wanted to add some handy functions for checking multiple values at once, using variadic templates.
So this is code I wrote (my thoughts were "oh, is it that simple?").
https://pastebin.com/HcDS7zmz
It compiled, run... but tests were failing for some reason...
I investigated a bit and found out that only the first values are considered in the function calls, and it seemed like I didn't actually use variadic templates. Seems like I used some kind of variadic functions (never used them before, so can't be sure).
Finally, I've rewritten it using real variadic templates. Become much more verbose, but at least it works correctly now (the bitset size is still not good, I'll replace it with magic_enum library call magic_enum::enum_count<T>() ).
https://pastebin.com/Dtxw0rTu
Funny thing that if I didn't write tests for it, I could leave this code as it was and added some hard to catch bugs to my project. And I decided to write the tests only because the code was actually crashing (as I understand because of stack overflow on the bitset allocation, because of too big size).
I found a way to significantly reduce code size (almost 3 times) and to improve readability of that code with C++17 fold expressions.

Hi everyone, I implemented stack using linked list in C. For compiling I use gcc.
On fedora my code works fine.
if I run on windows with gdb everything works fine too. But without -g flag malloc function causes segmentation fault.
Part of the code is posted here https://pastebin.com/FP3BvLvn. Segmentation fault appears after I use push function second time.

Editor? Could be. IDE? It's not even an IDE
Seems like he loves his own universe. :D

It seems like many people don't know the difference between an IDE and an editor

Unfortunately....
A quick Wiki trip could solve most things though....

Chill, vim might suffice for his purposes. Wouldnt call it ide though

Because it's not an IDE. You can tune it to make it feel almost like an IDE, but it's not one

Yep, most people misunderstand this.
Atom is not an IDE too, "a customizable modern code editor" at most. But you can customize it so much that most people think it's an IDE.

what are you talking about?

i just hear of that, if you want to start a war in a IT group ,you just say "xxx is the best langue/ide in the world"

anybody know anything about win32 api?
Artöm
Ms has good docs, go read them
Artöm
Or ask concrete question
Artöm
You can
Daniele
aight
Daniele
so the question is: I'm using visual studio to create the .rc file. to create a menu I used the gui and everything works, but I have no idea how to make an item of the menu checked or not
Daniele
the reference for this would be notepad's word wrap menu item, it's checked when word wrap is on and clean when it's off

My advice: use Qt for building interfaces

actually i lied i was talkin about win.h lol

Why would you? The good practice is to use crossplatform solutions, like Qt for GUI, boost for networking, interprocess communication, etc
Good luck with learning Win32 Api

sometimes people want to learn something the hard way to appreciate the easy way

i like that mentality
Daniele
I don't like Qt

also, of course I've been looking at the documentation for a long time, but my question was rather specific

maybe it's written in the documentation, I won't say it can't, but I haven't been able to find it so I asked if anybody knew

set though its property, i guess it's name 'checked'. Searh in MSDN for details

win32 api support u powerful access to system. And it can be run without mangle library or extenal SDK. Easy for build and deploy

I found that property, but I have to idea how to toggle it properly

You forgot that you install library while installing win32
Đỗ
set it directly though obect, for i.e. A.checked = true
If u using win 32 api, call it though appropriate function
...
wat, please tell me, which library do you install under a windows system to use the winapi?
András
wat, please tell me, which library do you install under a windows system to use the winapi?
While you install c++ packet there is option win32
Đỗ
Nothing, its has been pack in Operating System. But may be some api function has been depreacated, so u must be check and verify before using it
...
nope wrong, *most* winapi functions call into the ntdll which is shipped with every windows installation

Bit you cannot use wipapi without installing it(yeah, I tried)
Daniele
well of course you need the windows sdk for it, if you install vs2019 it's included, otherwise you need visual studio build tools
...
how can you not?

András

Yeah, I used vs17, and had to install windows sdk with build-in libraries
...
yes you can, take a look at the ss, all functions are exported
Daniele
heh why would you tho?
