self referential structure is used to create data structures like linked lists, stacks, etc. Following is an example of this kind of structure:
struct struct_name
{
datatype datatypename;
struct_name * pointer_name;
};
A self-referential structure is one of the data structures which refer to the pointer to (points) to another structure of the same type. For example, a linked list is supposed to be a self-referential data structure. The next node of a node is being pointed, which is of the same struct type. For example,
typedef struct listnode {
void *data;
struct listnode *next;
} linked_list;
