What sort of errors? And it is so difficult to understand your code with the variable names you have chosen. I understand that you are trying to simulate SJF. But the main problem with SJF is that short running processes can arrive at any time preventing a long running process from ever executing. I don't see you trying to do that.
Explain what you are trying to do and maybe we can help you then.

I removed your warning because your initial question looked like you were asking for code without showing what you have done. Read the rules

Hello guys,
what is better for release build (which i will give to users):
1) link all dlls into one exe
2) deliver exe along with dlls near it
Under dll I mean something standard like libwinpthread-1, so it's not my libraries

Separated libraries allows partial updates or may be used by multiple programs but I guess neither is your case
Separated libs might be enforced by its licenses like L-GPL
In case of small apps single standalone binary is cute in my opinion.

If the target is Windows I think it's okay to use dynamic link as It allow multiple application reuse same library, Static link if the customer didn't want or need to install needed library

While in Linux world, Libc often broken so its suggested to use static linking eh

is qt for designing GUI?
Qt is a framework created for developement the GUI's more advanced the sample form with resources like Widgets, QML, Qt Designer... So you can use Qt for many languages, but the principales language is C++ e Python. In first place you must know the documention and I know that in begin everything is dificult, but only read. And after read and watching some videos you going understand. Also make the course that can be pay because free courses it's not recommendable for who getting started.

im noob but i think it used to program software backend too
and the more you use qt the more you understand how it works. One of the things that Q5 also allows is styling the GUI's with CSS which is beautiful. So I love Qt.

dlls are dynamic libs that are loaded by Window OS, it is not part of the exe.
FriedRice
The good thing about it is Windows only needs to load it once and do virtual memory mapping into all processes that need it. The drawback is apparently due to the same reason, there is only one copy in the physical memory so it can't have global variables.

hi do I need to learn c++ to use c++ in unreal engine?

there are 3rd party libraries used by the developer which depends on the working of program, so i think they are asking if they should distribute their program as a statically linked binary or bundle the libraries into their program folder which is to be copied to system during installation

I mean most part of dlls have static version (.lib) which I can link with exe

I need gcc compiler to use neovim on windows. But I can't find any way to install it without mingw64 or cygwin. To use neovim in powershell I guess gcc also should run on powershell.
\Device\NUL
Me use winget install Neovim.Neovim
\Device\NUL
There are prebuild binaries

Then why not use it?
Error detected while processing C:\Users\zawkin\AppData\Local\nvim\init.lua:
No C compiler found! "cc", "gcc", "clang", "cl", "zig" are not executable.
zawkin | 🇵🇸
that's the error. Should I install gcc with ming64?

Did you have any installed compilers? Add it into the PATH
\Device\NUL
with scoop
What Windows version that you currently using? winget should have be installed
zawkin | 🇵🇸
\Device\NUL
It's the official package manager from Microsoft
\Device\NUL
not yet, ok
I recently installed the msi package, they have included some external lib like pthreads
\Device\NUL
So no need to use additional toolchain

Hi

Hi everyone, I'm working on a school project, building a vending machine with RFID, I'm storing a valid tag UID so I can validate it when the RC522 module read the tag and despite l'm using a const String for the Valid UID, the comparison between the read Tag and the string of my valid tag UID keeps unvalidating my tag. This is my code:
void loop() {
if (mfrc522.PICC_IsNewCardPresent() && mfrc522.PICC_ReadCardSerial()) {
String uidString = "";
for (byte i = 0; i < mfrc522.uid.size; i++) {
uidString += String(mfrc522.uid.uidByte[i] < 0x10 ? "0" : "");
uidString += String(mfrc522.uid.uidByte[i], HEX);
}
// Compare the UID with the validUID
if (uidString == validUID) {
Can someone help me correct it? I assume that it is due to the format or size between my valid UID string and the one scanned with the RC522 module
But i dont know how to correct it

I updated the variable names and understood my mistakes.😅

check uidString and validUID value using serial print before this line

if (uidString == validUID) {

Just drop vim and use vscode instead tbh. You can install vim extension on vscode. Vim is too old.
FriedRice
because there are too many new features in C++ like auto decltype template stuff, they require a modern IDE like vscode to analyze the context and give you hints. Without the help of the IDE it would be really hard to track type deductions in very long code using the bare human brain. vim is a good editor but not as good as a modern IDE.

It is an IDE depending on how you define an IDE
Danya🔥
And the same engine can be and is used by vim and the functionality is very same
FriedRice
You can compile, debug, and do tests on vscode.
Danya🔥
And the same can be done with vim

No, it doesn't
Microsoft itself calls it an editor, not an IDE
FriedRice
Fine, it is not an IDE. If you look at the C++ extensions you will notice a lot of the extensions are ported from Visual Studio.

The Microsoft extension is not useful for anything serious

Only the debugging functionality is nice but works not great sometimes

IDK what makes you think so
FriedRice
They share the same code

Just ported with different frontend

The quality of intellisence is very low
It's better to use clangd LSP
And it can also be used with vim

I learned that 5-6 years ago in college

Intellisense is decent I rarely found any issues, the last time I found were some false alarms in a very complicated C++ design pattern which a friend class was not recognized properly and MS literally fixed it in a pre-release next week, it is being actively developed right now and they will fix any bugs you find.
FriedRice
And it's free service that's really good.
FriedRice
I use vim key mappings in vscode tho, I have used vim for around 6 years since I learned programming in college. Although I still use it sometimes during work but only for some basic server settings 😂

I checked the clangd docs it needs to work with cmake_compile_commands.json. I will try that later but part of my daily job software doesn't have cmake 😂 just pure make files with many trick scripts inside and I hate it a lot.
