Self Referential Structure

Self referential structure contains a pointer variable of itself . it is mainly used for implementing data structures like stack, queue, linked list, trees and graphs in C.
Example

struct NODE

{

float data;

struct NODE  *link;

};

int main()

{

struct NODE *START = NULL ; 

struct NODE *N ;  

N = malloc(sizeof(struct NODE) ) ;  

printf( “Enter the data part of node \n ” ) ;  

scanf(“%f”,&N->data) ;  

N->link = NULL ;  

if( START == NULL )  

  START = N ;  

else  

{  

  N->link = START;

  START=N;  

  }  

}
