A void pointer...as it can be type casted to point to any
data type.

Answer / rpr

In linked list a 'pointer' points to the next node which is written in a 'structure'. so we will use "struct node" as pointer data type.

struct node
{
void data; // void can be used here for heterogenous data
struct node *ptr;
};

Answer / ajay vikram

The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a generic pointer type.
