Consider the following ANSI C program:#include <stdio.h> #include <stdlib.h> struct Node{ int value; struct Node ⋆next;}; int main(){ struct Node ⋆boxE, ⋆head, ⋆boxN; int index = 0; boxE = head = (struct Node ⋆) malloc (sizeof(struct Node)); head -> value = index; for (index = 1; index <=3; index++){ boxN = (struct Node ⋆) malloc(sizeof(struct Node)); boxE -> next = boxN; boxN -> value = index; boxE = boxN; } for (index = 0; index <= 3; index++) { printf("value at index %d is %d\m", index, head -> value); head = head -> next; printf("value at index %d is %d\n", index + 1, head -> value);}}
Which one of the statement below is correct about the program ?

Question


#include <stdio.h>
#include <stdlib.h>
struct Node{
int value;
struct Node ⋆next;};
int main(){
struct Node ⋆boxE, ⋆head, ⋆boxN; int index = 0;
boxE = head = (struct Node ⋆) malloc (sizeof(struct Node));
head -> value = index;
for (index = 1; index <=3; index++){
boxN = (struct Node ⋆) malloc(sizeof(struct Node));
boxE -> next = boxN;
boxN -> value = index;
boxE = boxN; }
for (index = 0; index <= 3; index++) {
printf("value at index %d is %d\m", index, head -> value);
head = head -> next;
printf("value at index %d is %d\n", index + 1, head -> value);}}
