How much math I need Hi, I know C and C++, and I want to build my own VST (Virtual Studio Technology) software. But first, I need to learn JUCE. I know this will require some math. I have a basic understanding of math, like precalculus, but I don't have a strong grasp of calculus. Should I learn JUCE first, or should I focus on improving my math skills first?. https://redd.it/1lsyqps @r_cpp

contracts and sofia Hey, Can anyone share the last info about it? All i know is that bjarne was really displeased with it from some conference talk about all the 'pitfalls' (the biggest foot guns we've gotten in a long time!), but I havent seen any more recent news since. https://redd.it/1lsy7sc @r_cpp

Advice For Game Dev Hi everyone❤️ I'm new to CPP but that's not my first time coding, I was coding in C for a month and I was watching( bro code) playlist no doubt you know him guys😅 so when I finished that playlist I asked myself should I dive more in C or switch to CPP 🤨 cuz my main goal is to be a game dev in CPP, and C will not help me at all in that way, cuz I'll use unreal engine for my games and that engine is using CPP😐 but before I ever started coding I asked Chat GPT for an advice and what should I do and he told me that I should start with C to know more about coding and something like that🫠🫠 so now I wanna start learning CPP and I want some Advice but from real trusted devs not Chat GPT 😂 https://redd.it/1lsd6kp @r_cpp

Code Coverage Gutters in VSCode? I’m returning to working with C++ after a several year hiatus. In that time, I’ve learned to appreciate some nice tooling ecosystems from languages like Go, which have easy support for displaying coverage gutters to illustrate which lines have been executed from tests. My question is: what would be the easiest equivalent these days for C++, specially for llvm-based builds using cmake? I’ve found a few outdated threads/topics, but I’m unsure if there is anything more recent. Best I can come up with is: 1. Use a cmake variant for generating coverage content 2. Configure a coverage gutters plugin to read the *.info file that will be generated in a consistent place under a “build” directory 3. Have a VSCode task that I can manually trigger to run the tests (through ctest) and then generate the coverage report with llvm-cov Am I on the right track? Is there anything easier/less manual? Does anyone have any tips/configuration options that they may be willing to share? https://redd.it/1lrz11b @r_cpp

for range vs index based for loop 2 codes with the same everything but different for loop style the range-based loop took more time than index for loop is it always true that index for loop is faster than range loop ? which one do you recommend to use ? because it is not allowed here to put a video ,I recorded a vedio it's almost one minute showing the difference in time , it is on my post profile (the most recent post) . link of the post https://redd.it/1lrydbu @r_cpp

Wasmbind Hello all I’m working on a project called wasmbind, which consists of 2 libraries, jsbind and webbind. The goal of the project is to provide a C++ interface to the browser’s DOM when targeting wasm. Currently jsbind provides just the minimal interfaces required by webbind. The webbind headers and sources are generated from webidl files. This allows for a more idiomatic, and less stringly-typed, api than for example emscripten’s val api. It’s also backend-agnostic, and can be used with stock clang targeting the wasm32-unknown-unknown (freestanding) target, so you don’t need to install additional special versions of clang. It can also be used to target wasm32-wasi and emscripten. In essence it’s similar to the widely-used web-sys crate in the Rust ecosystem: https://crates.io/crates/web-sys Link to the wasmbind repo: https://github.com/MoAlyousef/wasmbind https://redd.it/1lrr8zl @r_cpp

First cpp/opengl project it shows all 9 planets orbiting in real time with gravity, and there's a wobbly grid that bends around the planets like space-time. you can click planets, edit their mass, position, velocity etc and see what happens. no game engine, just raw opengl + imgui + glm. learned a lot building it so figured i'd share :) (i know the UI is kinda broken and there are bugs, but it was fun for a first project) here's the github if anyone wants to check it out: https://github.com/lucas-santoro/SolarSystemGL https://redd.it/1lrpplq @r_cpp
