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\n", index, head->value); 
		head = head->next; 
		printf("Value at index %d is %d\n", index+1, head->value); } } 

Which one of the statements below is correct about the program? 
 

Consider the following ANSI C program.

The output of the program upon execution is \(\underline{\hspace{2cm}}\).

Consider the following ANSI C program. 

#include <stdio.h> 
int main() 
{ 
	int i, j, count; 
	count = 0; 
	i = 0; 
	for (j = -3; j <= 3; j++) 
	{ 
		if ((j >= 0) && (i++)) 
		count = count + j; 
	} 
	count = count + i; 
	printf("%d", count); 
	return 0; 
} 

Which one of the following options is correct? 
 

Consider the following ANSI C function: 

int SimpleFunction(int Y[], int n, int x) 
{ 
	int total = Y[0], loopIndex; 
	for (loopIndex = 1; loopIndex <= n - 1; loopIndex++) 
		total = x * total + Y[loopIndex]; 
	return total; 
}

Let \( Z \) be an array of 10 elements with \( Z[i] = 1 \), for all \( i \) such that \( 0 \le i \le 9 \). The value returned by SimpleFunction(\( Z, 10, 2 \)) is \(\underline{\hspace{2cm}}\).
