Chapter 13.1, Problem 3STE
Program Plan Intro
Linked list:
- Linked list denotes a linear data structure.
- The elements are not stored at contiguous locations; the elements are linked using pointers.
- It stores linear data of similar types not like arrays.
- The size of linked list can be changed based on requirement.
- It is represented by a pointer to first linked list node.
- The first node denotes a head.
- If linked list is empty, value of head is NULL.
- The node in a list has two parts, data and pointer to next node.
Given code:
//Define a structure
struct Box
{
//Declare variable
string name;
//Declare variable
int number;
//Define pointer to next
Box *next;
};
//Create an instance
BoxPtr head;
//Assign value
head = new Box;
//Assign value
head->name = "Sally";
//Assign value
head->number = 18;
//Assign value
head->next = NULL;
//Display value
cout << (*head).name << endl;
//Display value
cout << head->name << endl;
//Display value
cout << (*head).number << endl;
//Display value
cout << head->number << endl;
Explanation:
- The “Box” defines a structure with “name” and “number” as members.
- It contains a pointer to next element of list.
- The “BoxPtr head” creates an instance of structure.
- A new “Box” element is created.
- The values of “name” and “number” are been set.
- The values of “name” and “number” are been displayed.
- The member variable next to the node is been set to NULL.
Complete program:
//Include libraries
#include<iostream>
#include<string>
//Use namespace
using namespace std;
//Define a structure
struct Box
{
//Declare variable
string name;
//Declare variable
int number;
//Define pointer to next
Box *next;
};
//Define instance
typedef Box* BoxPtr;
//Define main method
void main()
{
//Create an instance
BoxPtr head;
//Assign value
head = new Box;
//Assign value
head->name = "Sally";
//Assign value
head->number = 18;
//Display value
cout << (*head).name << endl;
//Display value
cout << head->name << endl;
//Display value
cout << (*head).number << endl;
//Display value
cout << head->number << endl;
//Delete
delete head;
//Display message
cout<<"List head is been destroyed"<<endl;
//Pause console window
system("pause");
}
Explanation:
- The “Box” defines a structure with “name” and “number” as members.
- It contains a pointer to next element of list.
- Define a main method
- The “BoxPtr head” creates an instance of structure.
- A new “Box” element is created.
- The values of “name” and “number” are been set.
- The values of “name” and “number” are been displayed.
- The member variable next to the node is been set to NULL.
- The linked list is been destroyed using “delete” statement.

Inspect the code and in your own interpretation, describe the reason parameter n in ChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? Write a function called void swap with two parameters, which will receive the address of x and y as pointer. The function should swap the value of x and y only if x is larger than y. Print the value of x and y after the function call. Write a function called double getAverage(int *array, int SIZE), where it accept the array as pointer, and return the average of the array. Print the returned value from this function. Always use *array rather than subscript to access the array value.arrow_forward
