1. Macro takes parameters where as ordinary definition does
not.
2. Based on the parameter values to macro it can result in
different value at run time. Ordinary defination value
remains same at all place at run time.
3. Macro can be used for conditional operations where as
definition can not.
4. Using macro one can achieve inline functionality in C
ie. macro can be a function performing simple operations.
This is not possible using definitions.
