本文探讨了在编程中使用枚举而非常量的原因。主要区别在于枚举不分配存储空间，而常量可能需要静态存储。文章通过具体示例解释了这一概念。
Often you'll see enum { SOMETHING = 2232; } (like that; unnamed enum with one value only) instead of const int SOMETHING = 2232;. It's because enum never gets any storage while const variable is still a variable and will get (static) storage if the compiler can't proove it won't need one, which it often can't.
