It's nothing at all how like C runs on top of assembly. C has semantics. Code means something without ever being run. You can check in your source code and (assuming it actually follows the C standard and your compiler's documented extensions, which almost no real C code does - C was a horrible example) it will work just as well in a year as it does today.

Try checking in only your prompts and nothing else. Just the parts you actually typed. See how well it works to regenerate the same application next week, let alone next year. Prompts are fundamentally a different sort of thing from code. Do not mix them up.
