Answer / naveen shukla

we uses structure pointer when we have to point to the whole
object and we can access all the values of the data in the
object.
when we want to keep the reference of the structure variable

Suppose I want to write a function that takes a generic pointer as an argument and I want to simulate passing it by reference. Can I give the formal parameter type void **, and do something like this? void f(void **); double *dp; f((void **)&dp);
