Difference between Enum and Define Statements

Question

What\'s the difference between using a define statement and an enum statement in C/C++ (and is there any difference when using them with either C or C++)?

For exampl

Answer 1

Another advantage of an enum over a list of defines is that compilers (gcc at least) can generate a warning when not all values are checked in a switch statement. For example:

enum {
    STATE_ONE,
    STATE_TWO,
    STATE_THREE
};

...

switch (state) {
case STATE_ONE:
    handle_state_one();
    break;
case STATE_TWO:
    handle_state_two();
    break;
};

In the previous code, the compiler is able to generate a warning that not all values of the enum are handled in the switch. If the states were done as #define's, this would not be the case.
