Difference between #define and const in C?

Act I: #define
Magic of preprocessor for global changes.

Act II: const
Type-safe, acts like a variable, constant data.

Act III: Scope Control
Avoids global exposure, prevents errors.

Act IV: Build-time Config
#define for flexible build-time config.

Storage Chronicles:
#define substitutes, const in read-only memory.

Grand Finale: Choose Wisely
Blend #define’s dynamism, const’s reliability.

Happy coding!
