What Is The Benefit Of Using Const For Declaring Constants Over #defi

1.	What Is The Benefit Of Using Const For Declaring Constants Over #define?
Answer» The BASIC difference between them is that, a CONST variable is a real variable which has a datatype and it EXISTS at run TIME, and it can't be altered. But a macro is not a real variable, but it carries a constant value which replaces all the OCCURRENCES of that macro at the time of pre-processing. The basic difference between them is that, a const variable is a real variable which has a datatype and it exists at run time, and it can't be altered. But a macro is not a real variable, but it carries a constant value which replaces all the occurrences of that macro at the time of pre-processing.
