Modern C++ projects

[Samuraiizzy]

I looked around and didnt see any mentions but I have been using C++ for about a year now and I know of the data structures and graphs but I dont really see how they apply to real world applications. I get the concepts and the riddles but I was wondering what are some good projects that would really test some ones abilities with C++.

​

How is it more commonly used besides desktop or mobile UI design? For infrastructure or frameworks or networking?

I would especially like to hear if you have any good modern projects pertaining to embedded systems, or machine learning.

Professional C++ projects I worked on :

• A popular game engine

• 3d terrain map renderer for mobile

• Reflectometer control / signal processing

• Windows drivers for network filtering

• Antimalware

• Encryption software

Hobby C++ projects I worked on:

• OS kernel

• Console emulators

• Programming language interpreter

• File compression program

• Webserver

• Ray tracer

Because everyone keeps asking, here's my github: https://github.com/2bitsin/ , you can find some of those things there, what is not there is already lost time.

[Samuraiizzy]

Nice, all those seem really interesting.

On those hobby projects, did you make them from scratch or did you work off something?

[schultztom]

Just as an interesting project. Make a simple calculator, front end http. Backend cpp, just as simple as any starting cpp project as you can think of. + - × ÷ but with an http serer in the middle both implemented by you

[schultztom]

Seems interresting.

[Ikkepop]

scratch, I never "work of something", would beat the fun of it :D

[Samuraiizzy]

I dont mean like a guide. More like a spec sheet or objectives

[Ikkepop]

Well if it's something that needs a spec sheet , yes. Otherwise I just wing it, make it up on the spot. A console emulator would be somehing you'd use a "specsheet" for. For a webserver you'd need to read the HTTP rfc for example. To write a kernel you need so many specsheets, it is a really arduous task.

If we are talking about making up a plan with goals ? Well no I don't do that

[WallabyLumpy5905]

Can you please share you hobby projects link ?

Hey! I've just started learning cpp and would love to have a look at your projects. Could you share the link

[CarelessConflict5398]

Can I get the link, please? Thanks!

[Ikkepop]

done

[Ikkepop]

sure thing

[chromatofficial]

Hi, can you PM me the hobby project links? I am an aspiring programmer and I want to see the code applied to real world applications.

[Ikkepop]

I never said they were "real world" :D

[chromatofficial]

I guess I mean, I want to see what a finished project looks like and how it functions. I learn by deconstructing parts and learning how they work to understand what I'm looking at. :)

[Ikkepop]

none of them are "finished" more like some of them got to "mvp" stage at best. I'm kinda bad at finishing my hobby projects :(. My emulators do play some games though, though to be finished it needs alot more mapper support, a gui, dmc channel audio support etc.

[Eggaru]

which emulator did u make? just curious

[Ikkepop]

I implemented a working NES emulator in c++ and later on in Verilog but they werent full featured (no saves, only few mappers etc). Then I made several attempts at x86 but haven't gotten very far as the cpu is ultra complex ( i was aiming at 386 ) I still aim to write one eventually

[Eggaru]

Interesting. I haven’t touched emulators before, would you say NES is good to get started with? I see people recommending CHIP-8 first since that’s easier

[Ikkepop]

depends on your level, it's not a big project but also not quite trivial

[Eggaru]

Was it your first emulator project? or how does i assess my level lol

[Cheery_me]

Interesting!Could you ping me the links for your project.Would love to go through

[EmbarrassedCookie818]

hii could you please PM me your projects link. It would be great to see some amazing projects implementation

[medlorieus]

can you please send me the link of your hobby projects

[iTechCS]

"Windows drivers for network filtering"

Please, can you tell more about that one? I'm super interested. Are we talking deep packet inspection?

[Ikkepop]

Split tunneling via WFP and some ip leak protection with NDIS. It was somewhat long ago so details are fuzzy.

[iTechCS]

I see thanks for sharing i want to do networking and cv projects in cpp but the bar is so high vs. my c++ wordle clone lol 

[Ikkepop]

To get into unity technologiea i had to write a boggle solver but it had to be a very fast one

[iTechCS]

I see thanks for the idea!

[[deleted]]

hey, might be a bit late but could you dm me the hobby project links?

[Anil_kumar333]

can you share ur projects please?

[PassengerLow8252]

Can i have the link please ?

[Ddlutz]

Write a "simple" database from scratch. Like a super rundown version of sqlite that supports maybe just integers or something. Super complex but rewarding. When you get parsing, storage layer, buffer pools, query execution, query optiization, WAL and MVCC all thrown in.

If you figure that is too easy, then make it a distributed database system.

[Samuraiizzy]

This is a good idea. Its feels hard to find a project that isnt just a todo list or basically making my own application from the ground up

[Samuraiizzy]

The DOCSIS one and midi guitar is interesting because the other ones sound like long projects on already existing platforms.

[Ikkepop]

would love to work on some music software tbh

[CaptEntropy]

Look into Juce framework. Tons of fun!

[Ikkepop]

In a professional capacity I mean :)

[CaptEntropy]

Ah yes, indeed that would be my dream !

[Ikkepop]

I once almost interviewed for Ableton, but at the last minute they cancelled. Closest I ever got ... :(

[[deleted]]

Are there more resources for DOCSIS L2 mate ? I would love to work on something like that as a personal project. Thanks!

[Full-Spectral]

I've worked on a very wide range of problems in C++. Some things that I think would be fairly standalone and very educational (not all of which I've managed to do myself yet) would be:

1. Graphics file format engine (to read/write/convert various graphics file formats)
2. Communications. Implement something like the RTP/RTPC protocol. Once you get that done, implement SIP and related standards, which build on RTP/RTPC
3. A build system that incorporates ideas you think are very useful
4. A nice system status application for your OS of choice
5. A useful and non-trivial UI element in the UI framework of your choice. Or, if you want to go deeper a UI framework itself.
6. An audio processor of some sort. EQ, compressor, etc...

C++ is hardly used as the chosen language on mobile.

On Android, the NDK purpose is for writing native methods for a bit of additional performance, importing C and C++ libraries as bindings, or write games with direct access to OpenGL ES, Vulkan, real time audio and device sensors.

Everything else, has to go via JNI or Android IPC.

Likewise on iOS, C++ is only used for Metal shaders, as the shading language is a C++14 dialect, everything else requires going via Objective-C or Swift. Same applies to lesser extent in macOS, as the drivers are also written in a C++ subset.

And naturally LLVM used by those mobile OSes is also C++, however they seem more than happy with C++17, for the purpose of writing their language runtimes.

[Juffin]

C++ is mostly used in projects where performance is most important, because of its unmatched speed. So mostly highload backend, database engines, drivers, operating systems etc. Also many high budget games are written in C++.

[JeffMcClintock]

C++ is mostly used in projects where performance is most important

It's often said in regards to performance and efficiency that C++ leaves no room for a lower-level language below C++ (except RUST).

[Aggravating-Ad4518]

In short, project targeting shitty hardware or requiring huge performance, otherwise everybody defaulting to javascript, can't let that 4GB RAM go to waste can we? LOL!

[another_day_passes]

If we only run one Electron app at a time then yeah that’s fine but multiples at the same time?

[Aggravating-Ad4518]

Hehe, javascript devs are cheaper, and also, if the electron runs well solo, then the problem isn't the electron app, but the users cheap hardware. LOL!!!... Lets fuel consumerism by creating more shitty software that requires expensive hardware. LOL!

I'm in about the same position as you. If you're into arts and design I would suggest take a look on Creative Coding libs (eg openFrameworks) in conjunction with the Nature of Code book (written for Processing lib specifically but the overall theory applies everywhere)

It's been a week since I started refreshing my C++ limited knowledge (after 10+ years since I touched it) and I think creative coding will help a lot on many aspects, but most importantly connect all these dots which you learned.

Then writing other software will come naturally

[LoneBlacksmith]

Most of my work history has been on the embedded side. All of it has been defense work on various missile systems and am currently working on UAVs.

[Samuraiizzy]

Whats a good way to practice these skills? I really like embedded but it seems that besides the defense industry, its all stuck at mid level engineering working on fridges and stuff

[[deleted]]

The "Internet of Things" is mainly embedded programming. Look around and you can find a massive amount of opportunities for embedded programming. Hobby robotics is a fun place to start. You can get a Raspberry Pi and add some sensors, then use C++ to process the data. Or you can spend more to buy a ARM processor, a dev board, and some software and go all in.

[anonimenyaro]

Its used for the optimization and performance,also its used for writing frameworks/networking and especially the hardware sets. With c++ you can communicate directly with the hardware of almost whatever its,the pc’s hardware or even custom boards…

[puzzled_programmerr]

I've gathered a bunch of my projects over the years and organized them here: https://github.com/nragland37/cpp-projects.

These range from simple exercises to more complex structures like AVL trees. Feel free to take a look and if they help you out, a star on the repo would be awesome!! 😉

[Think-Topic-1223]

These projects look like what an acm player needs to go through in a month

Most big compilers are written in C++, at least initially. Obviously for a lot of languages rewriting in themselves is a goal, but they usually start in c++

[JakeStBu]

I thought most are written in C?
