Establish a simple static linked list, which consists of 3 student data nodes, which require the output of data from each node.

Solution: The first1the start address of a node is assigned to the head pointerHead, the first2the start address of a node is assigned to the1a node.Nextmember, the first3the start address of a node is assigned to the2a node.Nextmembers. Section3a node.Nextmembers giveNULL, which forms a linked list. In order to create a linked list, theHeadPointinganode,A.nextPointingbnode,B.nextPointingCnode,C.next=nullthe role is to makeC.nextdoes not point to any useful storage unit.

Program:

#include <stdio.h>

struct Student

{

int num;

Float score;

struct Student *next;

};

int main ()

{

struct Student A, B, C, *head, *p;

A.num = 10101; A.score = 89.5;

B.num = 10103; B.score = 90;

C.num = 10107; C.score = 85;

Head = &a;

A.next = &b;

B.next = &c;

C.next = NULL;

p = head;

Do

{

printf ("Num=%ld score=%5.1f\n", P->num, P->score);

p = p->next;

} while (P! = NULL);

return 0;

}

Results:

num=10101 score= 89.5

num=10103 score= 90.0

num=10107 score= 85.0
