const double PI = 3.14159;
PI = 3.0; is now illegal!

• Constants must be initialized when they are defined.
• Constant values can never be changed.
• They can never appear on the left of an assignment operator, =

• Constants that are defined by using const are understood and checked by the C compiler itself immediately. So error messages are much more helpful.
• The #define directive is just substituted by the preprocessor and is not checked until the macro is used.
• const uses typical C syntax, while #define has its own syntax.
• const follows normal C scope rules, while constants defined by a #define directive continue on forever.
• The #define directive can only define simple constants.
• The const statement can define almost any type of C constant, including things like structures.
• The #define directive is essential for things like conditional compilation and other specialized uses.
