Question

1. Struct (Optional: 1 point)
1) Use the following abstract data type called Rectangle to get the length and width from
the user.
2) Display the length, width, area, perimeter, and whether the rectangle is a square.
struct Rectangle
{
float length;
float width;
float area;
float perimeter;
};
2. Linked List (Optional: 1 point)
Modify the following program to make a node containing data values of int, char, and string:
#include <iostream>
using namespace std;
struct Node
{
int data;
struct Node *next;
};
struct Node* head = nullptr; //or NULL or 0;
void insert(int new_data)
{
struct Node* new_node = (struct Node*) new (struct Node);
new_node->data = new_data;
new_node->next = head;
head = new_node;
}
void display()
{
struct Node* ptr;
ptr = head;
while (ptr != NULL)
{
cout<< ptr->data <<" ";
ptr = ptr->next;
}
}
int main()
{
insert(2);
display();
return 0;
}

1) Create a linked list of ten nodes (each node contains the three types of data values).
2) Display the data values from the linked list.
3. Linked List in both directions (Optional: 1 point)
Modify the program from Question #2 so that your program displays the data values from
the linked list in both forward and reverse directions.

4. Using the style of Object-Oriented programming (OOP) to create or instantiate three
Rectangle objects or instances with different sizes (Optional: 2 point). You may start with
the following class definition or something else you prefer.
class Rectangle
{
private:
double width;
double length;
public:
void setWidth(double);
void setLength(double);
double getWidth();
double getLength();
double getArea();
};
