GATE 2025 Programming & Data Structures Foundation Quiz 3

Consider a 2D array A[-5….5][10……15], the base address is 100 and word length 2B find the address of the element A[2][13] using Row major order?

What is the output of the following program in a 64 bit machine?(int will take 4 byte)
int main()
{
int a[] = {2, 3, 4};
printf(“%d %d %d”, sizeof(a), sizeof(&a), sizeof(a[0]));
}

Consider the following linked list.

Following operations are performed on this singly linked list:

i) struct node *p;

ii) p = s --> next -->next-->next-->next;

iii) s --> next -->next-->next = p -->next-->next ;

iv) p = s --> next -->next-->next-->next;

v) p --> next = s --> next -->next;

vi) Pf(s --> next -->next-->next --> next -->next-->next --> next -->next-->next--> next -->next-->next-->data)

What will the last statement print?

What does the following code do (head is pointing to first node)?
void fun(struct node* head)
{
if(head == NULL)
return;
printf("%d ", head->data);
fun(head->next)
printf("%d ", head->data);
}

Consider the following Linked List and perform the following operations:

Let temp be the pointer to the first node

p = temp -> next

temp = p->next ->next

p -> next = temp -> next

What will be the result of (temp ->data) – (p->next->data).
