CODING LABS
Practice the difficult parts of C programming with hands-on challenges.
Memory Lab — Understand stack and heap memory through interactive scenarios.
Segfault Hunt — Find and fix a new buggy C program every day.
Compile or Crash? — Decide whether C code compiles, runs, or crashes.
Speed Arena — Solve coding problems where performance matters.
Build Series — Build practical programs such as your own malloc, shell, and grep step by step.
Visual Output — Experiment with LEDs and 7-segment displays using C output.
20 GUIDED C PROJECTS
Build real C programs and learn how larger projects are structured.
Projects include linked lists, an RPN calculator, word counter, configuration parser, state machine, generic stack using void*, qsort comparators, fixed-point mathematics, error handling, snprintf parsing, and multi-file projects.
Every project is designed to compile and run end to end.
