#include <stdio.h>

#include <math.h>

int main() {

    int x = 16;

What is the output of this program?

int a[] = {1, 2, 3};

int cnt = 0;

for(int i = 0; i < 3; i++)

    for(int j = i+1; j < 3; j++)

        if(a[i] + a[j] > 3) cnt++;

printf("%d", cnt);

#include <stdio.h>

void print(int n)

{

    if (n == 0)

What will be printed by the following code?

void printList() {

    struct node *p = head;

    while (p != NULL) {

        printf("%d ", p->data);

        p = p->next;

    }

}

If head == NULL, the output is:
