Why is it interesting to learn C?

Learning C is like learning to drive a manual car: it gives you a deeper understanding of the underlying mechanisms that higher-level languages abstract away.
In C, you can see how fundamental data structures like strings, hashmaps, and arrays are implemented and represented in memory.
In contrast, high-level languages hide these details from the programmer, managing them automatically.
Studying C also helps you appreciate the challenges faced by programmers when designing programming languages, particularly in handling dynamic data structures.
Unlike numbers, structures like strings and lists have unpredictable sizes, requiring careful management of dynamic memory allocation.
