Answer / subbu
While defining macro's for each parameter enclosing brackets
is preferred. For finding out greatest of two numbers better
way writing macro is as below.
#define Greatest(a,b) ((a)>(b))?(a):(b)
If this method not followed, the in the following example
results will be wrong.
#define Product(a,b) (a*b) /* Wrong method */
Bcz if call is done as below
Product(2+3, 4+5) then result will come as (2+3*4+5) = 19
instead of 45.
