This lab will exercise your understanding of some of the concepts covered in Chapter 14: pointers and linked lists 1. Declare an integer pointer variable intPointer. Initialize it to point to an int variable named someInt. Assign the value 451 to someInt and output (cout) the variable someInt and output (cout) the value pointed to by intPointer. Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer. Output (cout) the value pointed to by intPointer and output (cout) the variable someInt, 2. Declare a pointer variable charArrPointer and initialize it to point to the first element of a three-element char array named initials. Write assignment statements to store 'A', 'E', and 'W' into the first three elements of the array POINTED to by charArrPointer. Do NOT store any values directly into the array named initials. 3. Output (cout) the data in array charArrPointer and the data in array initials. 4. Copy the following code into your program above main: struct NodeType { int num; NodeType* next; }; 5. Copy the following code into your program after main: NodeType *newNode, *first, *last, *current; 6. Copy the following code into your program after the code you wrote for steps 1 - 3: newNode = new NodeType; newNode->num = 10; newNode->next = NULL; first = newNode; last = newNode; newNode = new NodeType; newNode->num = 20; newNode->next = NULL; last->next = newNode; last = newNode; newNode = new NodeType; newNode->num = 30; newNode->next = NULL; last->next = newNode; last = newNode; 7. Create a new NodeType node. Assign the value 1 to the num data member. Write the code to insert the new node at the beginning of the list. 8. Write the code to print the values of the data member num in the entire linked list.

Question
This lab will exercise your understanding of some of the
concepts covered in Chapter 14: pointers and linked lists
1. Declare an integer pointer variable intPointer. Initialize it to point
to an int variable
named someInt.
Assign the value 451 to someInt and output (cout) the variable someInt
and output (cout)
the value pointed to by intPointer.
Write an assignment statement that indirectly stores 900 into the value
pointed to by intPointer.
Output (cout) the value pointed to by intPointer and output (cout) the
variable someInt,
2. Declare a pointer variable charArrPointer and initialize it to point
to the first element
of a three-element char array named initials.
Write assignment statements to store 'A', 'E', and 'W' into the first
three elements of
the array POINTED to by charArrPointer. Do NOT store any values
directly into the array named
initials.
3. Output (cout) the data in array charArrPointer and the data in array
initials.
4. Copy the following code into your program above main:
struct NodeType {
int num;
NodeType* next;
};
5. Copy the following code into your program after main:
NodeType *newNode, *first, *last, *current;
6. Copy the following code into your program after the code you wrote for
steps 1 - 3:
newNode = new NodeType;
newNode->num = 10;
newNode->next = NULL;
first = newNode;
last = newNode;
newNode = new NodeType;
newNode->num = 20;
newNode->next = NULL;
last->next = newNode;
last = newNode;
newNode = new NodeType;
newNode->num = 30;
newNode->next = NULL;
last->next = newNode;
last = newNode;
7. Create a new NodeType node. Assign the value 1 to the num data
member.
Write the code to insert the new node at the beginning of the list.
8. Write the code to print the values of the data member num in the
entire linked list.
