C

C is the progenitor of programming languages - a powerful, low-level language that still powers everything from operating systems to embedded systems.

About C

C is like an old rock star that refuses to retire - created in 1972 by Dennis Ritchie and still highly relevant. It’s the language behind operating systems like Unix and Linux and the inspiration for many others (hello C++, Java and Go!). With its compact syntax and direct memory access, C is perfect for those who want to understand what’s happening under the hood.

But C is not for the faint of heart. There are no safety nets: you manage memory, pointers and buffers yourself. It’s like driving without ABS or airbags - you have maximum control and maximum responsibility. That makes C a favorite for systems programmers, embedded developers and anyone seeking maximal performance with minimal overhead.

Even as newer languages like Rust and Go rise, C retains a top position in popularity indexes. It’s a language that never truly goes out of style - perhaps because it keeps you close to the machine without writing raw assembly. If you want to learn fundamentals properly, C is a language you shouldn’t miss.
