Why Do We Still Use C in 2026 ?



Did you know that the C programming language controls everything from roads to space? 🚀 From traffic lights and cars to aircraft, ships, and even space missions like NASA’s Mars Rover, C plays a vital role in our world. 🌍 Dive into how C powers OpenCPN, the open-source maritime navigation software, and much more! Watch till the end to discover why this language is still irreplaceable in critical systems worldwide. 🛠️✨”

  1. "A Book on C: programming in C" by Al Kelley & Ira Pohl ans "The C Programming Language" by Brian Kernighan & Dennis Ritchie are great starting points. I still have both from way back when.

    C is simple, but profound. Mastering computing concepts in the context of C forms a strong foundation.

    Remembering that C considers Zero to be in the set of Natural Numbers, and not blowing past the end of arrays are the hardest parts of C!

  2. A PDP-11 running UNIX in the early 80's.

    A vi editor on a monochrome terminal (amber was best) & a cc compiler.

    Me, a young, sexy, Physics Major …. well, young, at least.

    My code, "SEGMENTATION FAULT. CORE DUMP"

    And those were the Good Ol' Days!

  3. C is awesome! I wrote a book on C – "C programming Explained Better". There is no grey area in C…it's so straight forward and it works very well without bugs popping up when it's written correctly.

  4. Talking about WHAT uses C, is not any prove of WHY C is better! Also, calling C a low level language on a par with ASM is also not true. C is a higher level language than ASM. In fact, many C apps are converted to ASM on the fly. But I agree C is much closer (and better) than higher level languages. A mixture of ASM and C is the best code learning possible, for low-level coding.
