Enumerated constants of C++

Here's an example:

enum COLOR { RED, BLUE, GREEN, WHITE, BLACK };

This statement performs two tasks:

It makes COLOR the name of an enumeration, that is, a new type.

It makes RED a symbolic constatnt with the value 0, BLUE with the value 1 and so forth.

If you write:

enum Color { RED=100, BLUE, GREEN, WHITE, BLACK };

then the BLUE value 101, GREEN value 102 and so forth.

How to use:

Color c = RED;

if(c==RED)

{

}

else if(c==BLUE)

{

}
