Can you please anwser these c++ questions for me

1) If NodeTypePtr is defined to be a pointer type to a node in a linked list, then the declaration:-

NodeTypePtr head;

a)	allocates memory for the node that head will point to

b)	automatically makes head->link point to NULL

c)	allocates only the memory for a pointer variable

d)

2)

If you want to declare a node type struct and typedef a pointer type for that node, in which order must you make these declarations?

a)	first the node pointer, then the node, since the node has a pointer in it

b)	first the node, then the typedef

c)	it doesn't matter which order you do them in

you cannot do both of them in the same program

3)

If you need to insert an element in the front of a list with N nodes (and move the other elements back one place), how many nodes do you have to move?

0

1

N-1

N

allocates a linked list
