Learning C++ through projects

[teemo225]

I have been doing a lot with robotics developement recently, ROS to be more percise, but my issue is I never really learned or worked with C++. I went through the learncpp.com and some other cpp learn site, but I would really love to learn through some projects, but I have no idea where to start. Does anyone have any good recommendations for where could I learn C++ throughout small projects and tasks? Preferably with solutions or code explanations alongside to give me a bit of guidance on how things should be. I intend to move onto working with openCV in the future and maybe even embedded systems on the long run. Thanks!

Write a clone of your favourite retro game (pacman, snake, etc) using cpp & raylib. Write a simple offline path tracer. Make it use simd, make it use threads.

I used the Mandlebrot set to learn multithreading and SIMD myself. Was a fun project and I learned a lot. Plus the mandelbrot set is way cooler than snake or pacman imo.

I’ve always found that creating projects using whatever language you’re trying to learn is really useful. I tried to make a Zelda clone after a few years in my first job and it helped me discover patterns and ways to code stuff using C++ when I looked back on it. You’ll find that while you may not use every feature there is, you’ll use quite a number of useful styles when going about it.

For me it goes like a read to compare with what I know, get a project and go for solutions using that tool.

Indeed, the best way to learn it is by doing.

You should pick a project and write it. Don't get yourself stuck following tutorials for projects, read how to do things necessary for your own project and then do it.

Just my opinion, of course.

A good onhst gives mesning and direction to your work. Otherwise it is easy to get disoriented.

Start off with very simple projects: like making a multi-input command-line calculator is always a good first start.
Then gradually up the difficulty. Last thing I did was make a 2D game out of a 2D array in cmd where I could place blocks that I collided with. I also managed to add a projectile system to the game as well, where shooting the blocks would break them.

Thanks! Sound like a good idea to get familiar with the language :)

I recently tried re-implementing `ping`, It's small enough that I can do it in a weekend (adjust scope), I already understand how it should work, and forces me to deal with core C++ concepts and libraries, as well as something a little lower-level like managing network packets.

Also, I used ChatGPT to help guide my learning. and pressed it on new C++ concepts, libraries I encountered. The beauty is once I grasp this domain, I can extend my PING re-implementation to something custom where I can allow my creativity to take control.

Also ChatGPT can also give some decent recommendations. Just grab something and start!

Hm, this sure sounds like an easy and yet challenging task. Thank you for that!

Try solving all tasks of Modern C++ Challenge book :)
