C is a compiled, low-level systems language that gives you direct control over memory and hardware. Created in 1972, it went on to influence nearly every major language that followed and still powers operating system kernels, embedded devices, databases, and language runtimes today. Learning C means learning how computers actually work under the hood — no hidden abstractions, no safety nets, just you and the machine.

This tutorial series takes you from your first compiled program to advanced systems programming. You'll learn core syntax and control flow, functions, arrays and strings, pointers and memory management, structures and unions, the preprocessor, file handling, and classic data structures built from scratch. Along the way you'll pick up the tooling every C programmer needs — compilers, Make, GDB, and Valgrind — plus the hard-won lessons about undefined behavior and memory safety that make C both powerful and demanding.
