Difference between Enums and #define preprocessor

Hi
Can any one tell me the difference between preprocessor macros like
#define and enum;
If i want to define MAX_LIMIT=100 as preprocessor macro as

Code:

---

#define MAX_LIMIT 100;

---

or if i define

Code:

---

enum {MAX_LIMIT=100};

---

then what is the basic difference?

An enum can be type checked.
An enum will print the symbolic value if you try to examine it in the debugger.

That's just a silly use of enum. I hope you understand that. In this case, a const int would be better.
