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 ?
Consider the following ANSI C program
#include <stdio.h>
int foo(int x, int y, int q)
{
if ((x <= 0 && (y <= 0))
return q;
if (x <= 0)
return foo(x, y - q, q);
if (y <= 0)
return foo(x - q, y, q);
return foo (x, y - q, q) + foo(x - q, y, q);
}
int main()
(
int r = foo(15, 15, 10);
printf("%d", r);
return 0;
}
The output of the program upon execution is ________

int arr[4][5];
int i, j;
for(i =0; i<4; i++){
for (j =0; j<5; j++){
arr [i][j] = 10*i + j;
}
}
print("%d", *(arr[1] + 9));
return 0;
}
