Why Learn C in 2025–2026?
Even today C is extremely important because:
- Almost all operating systems kernels → Linux, Windows NT, macOS, Android kernel parts
- Most game engines (Unreal, Unity internals, Godot core…)
- Embedded systems & IoT (cars, washing machines, drones, medical devices)
- Compilers & programming language runtimes (Python, JavaScript, Rust, Go… are written mostly in C)
- Performance-critical software (databases, web servers – nginx, redis…)
- The best language to really understand how computers work.
