13.The value of x and y after the execution of following program would be:

void func( int *a, int *b){

int tmp = *a;

*a = *b;

*b = tmp;

}

int x = 5, y = 10;

func(&x, &y);

1. x = 5, y = 10
2. x = 5, y = 5
3. x = 10, y = 5
4. x = 10, y = 10

14. What will be the following function return value when you are passing n = 5 into it.

int func(int n){

int i, j;

for(i=1, j=1; (i<=n); (j *= i), i++);

return j;

}

1. 5
2. 0
3. 120
4. 1

15. Advantage of using linked list compare to array are_____________

1. They allow easy insertion of value and deleting it
2. It is easy to work with linked list while using stack and heap
3. They require less memory compared to array
4. They can reduce access time.
