Free C Courses

C is a single-course catalog here, and that course is a good one: MIT's Practical Programming in C, a beginner-level treatment of the language from the school that helped shape how it's taught. Be clear-eyed about who C is for in 2026. It's the language behind operating systems, embedded devices, and performance-critical code, and it's the best way to understand what higher-level languages quietly handle for you: memory, pointers, how data actually sits in hardware. It is not the fastest route to a first job. If getting hired is the near-term goal, start with Python or JavaScript and come back to C later, once systems or embedded work is what you're after. Learn it for understanding, not as a first step.
