        struct linked *index;
}linked;


    struct linked *temp1;

     int count=1;
     while(count<10){

           temp1->val=count;
           temp1=temp1->index;

           count++;

     } //end of while

     while(temp1!=NULL){
           printf(" %d\n",temp1->val);
           temp1=temp1->index;
     }
