const is used by compiler and define is performed by pre-processor.
const has scope while define can be considerd global.

suppose u wanted to write
# define a 10

and msitakenly u wrote
if( a.9 ) ........

in case a in const it can be caught by compiler...but if its #define ..it can't be caught and may pose a hard to detect bug :(
