As someone whose first "real" programming language was C, I recommend against writing anything new in C.
There are plenty of C projects you could consider contributing to as a way to learn the language (and if you want a long and prosperous career, knowing C can only help you) but language design has come a long way since the 70s and something like Golang or Zig or Rust would get you many of the advantages of C with many fewer pitfalls.
Zig, then.
I'm totally with you on this.
C is a fantastic language for people who want to develop for existing C projects. But there are very few reasons to develop new software projects in C today. As such, for anyone learning C, the best first project would probably be whatever existing C project you want to work on.
Maybe the main exception to that is probably embedded systems stuff for microcontrollers and the like, but I don't know enough about that space to say whether that is even still the case or whether you'd be better off with something else.
There's still plenty of jobs using C. C has certified compilers and libraries that let you use it in projects with security regulations like automotive. Those project are not moving to Rust or Zig anytime soon. They are also safe from AI (no one will dare doing anything "agentic" in safety critical projects) and with latest investments in the defense sector in Europe I would expect them to grow in the coming years. If I could change career paths today I would definitely consider C. Rust is great but it's really hard to find a job as a rust programmer.
I don't know about Europe. But the US (or at least the portion of the US federal government I deal with) has been trying to ban us from using memory unsafe languages for as long as I can remember. For us, Rust isn't replacing C; it is replacing Ada. The only difference is that they have stopped granting exceptions for new code bases in memory unsafe languages.
Yes, they are trying but C still dominates in many parts of industry. After learning C I would definitely start learning Rust but right now you will have way bigger chances of finding a job with C than with Rust.
The other side of this coin is C developers are still plentiful whereas folks who know rust are less available.
If someone knows C and Rust experience I’m hiring them over the others.
