these errors dont show up when running in mac terminal

[opaque stag]

idk, at quick glance I don't see anything explicitly super wrong

but

https://cplusplus.com/reference/algorithm/max/

min and max are already part of std

[dense hearth]

oh

[opaque stag]

(min > nums.at(i)) ? min = nums.at(i) : min += 0;

[dense hearth]

so should i change it to like minvalue or smth

[opaque stag]

probably

anyway, comment out all your code

then uncomment one line or one function at a time until you find what causes the error

[fierce yew]

https://godbolt.org/z/h1b7a1YKb it's not really a code issue but a tooling issue anyways, your code compiles

so maybe it's something like not compiling with the standard library and then everything else falls apart as a result

maybe this is being compiled as C for whatever reason, and not C++, etc.

ah I know what it is @dense hearth, you're compiling as C++98, which is still the default for Apple Clang

-std=c++20

[dense hearth]

so then why does vscode show all those errrs

[fierce yew]

I just said why

[dense hearth]

oh i didnt see ur msg below the link thingy

[dense hearth]

how do i make it compile in c++11 or 14 or 17 or 20 im just using the start compilation button

[fierce yew]

depends on how you're building this, but usually you should have a build.json or something where you can configure everything, such as the C++ standard

[opaque stag]

honestly, probably don't use VSCode, just use XCode instead

unless you want to learn a bunch of extra stuff 🤷

[fierce yew]

or if you're generating it from a CMake project, you can set that up by setting CMAKE_CXX_STANDARD

[dense hearth]

i tried xcode but it wouldnt let me compile/run a c++ file unless i make a new one it wont let me open a c++ file and run it it just opens as txt

[dense hearth]

i dont think i use cmake

[opaque stag]

I mean, I somewhat doubt that's entirely true, but why is that a problem? so just make a new project and a new file and copy/paste your old code

it doesn't seem like you have thousands or millions of files, really just one so far I think

and not a very large one at that

anyway, frankly you'll probably struggle if you try to use VSCode. while XCode requires some learning too, you'll probably have far less pain with XCode than anything else

for reasons detailed here https://cpp-doge.github.io/limbo/use-an-ide/#motivations

[dense hearth]

but id rather just be able to open it rather than just creating a new file i would have to delete the old one duplicates tend to bother me

also what abt codelite

[opaque stag]

hey, if you prefer to learn and study what you need to be successful, go ahead

but it won't be easy, and I detail this rather verbosely and explicitly in my post

[opaque stag]

I still feel this is a non-sequitur

if you use XCode you'll just be using XCode

like you may have to copy/paste 50 lines this once

any and all future projects should be no more or less work in general than creating a new file etc with any other tool

you'd have to create a new file and build and config for vscode pretty much every time anyway, it's not easier

[dense hearth]

do u know of any other good c++ ides

[opaque stag]

in fact it's overall much more difficult

[dense hearth]

what is

[opaque stag]

for you as a beginner on mac? no not really, XCode is kind of it

[opaque stag]

using vscode

Choosing an IDE/Editor

There is no "best" editor for C/C++. Each has its strengths and weaknesses.

IDEs (Integrated Dev. Envs.)

Specialized editors with built-in tools for building, running, debugging, etc. Heavier, but also much more powerful out of the box.

• Visual Studio (free, Windows)
• Xcode (free, macOS)
• Qt Creator (free, any OS)
• CLion (free for students, open-source, any OS)
• repl.it (free for open-source, in-browser)

Code Editors

Less language-specific editors, which are more lightweight. Extra tools for building, running, etc. can be installed via plugins.

• Visual Studio Code (free, any OS)
• Sublime Text (free, any OS)
• Vim, Emacs, Micro: (free, terminal)
  All the above work for many languages, not just C/C++.

More Alternatives

You can use practically any text editor, even Notepad to write your code. C and C++ can be compiled and run directly from the command line. However, this setup is difficult to use and to make as powerful as an IDE.

[opaque stag]

anyway, if you really want to go down the hard road, my post covers just about everything you could need or want to know about this stuff

my claim is that anything other than XCode on mac is "the hard road", ymmv

[dense hearth]

what channel is ur post in

is it here in #1013107104678162544

[opaque stag]

my blog post ☝️

https://en.wikipedia.org/wiki/List_of_text_editors

https://en.wikipedia.org/wiki/Comparison_of_integrated_development_environments

there are many to choose from, but the easiest, least painful path to coding instead of worrying about all this is to just use XCode, anyway, good luck

[dense hearth]

i didnt see anything abt mac or xcode there just windows and vs and vscode and mingw

[opaque stag]

that's an internal link

read from the top

it's not really an article that's OS specific, this general situation applies to tons of beginners in here

it's really common that beginners try to use VSCode, and this causes pain, and my general recommendation is to use the official IDE for your OS which is Visual Studio on Windows, XCode on Mac

so, the general premise applies across the board, all the reasons to use Visual Studio on Windows are basically the same reasons to use XCode on Mac

wait i got vscode to work i had to make a tasks json file i had to add -std=c++17 in the args section
