a)

Program Plan Intro

To construct the class Pol_coord along with the member functions convToPolar() and showdata().

a)

Expert Solution

Explanation of Solution

//class definition
classPol_coord
{
//two floating point data members dist and mathematical
    private:
floatdist;
float theta;

//constructor and function prototypes
    public:
Pol_coord();
voidshowdata();
voidconvToPolar(float,float);

};

//constructor function
Pol_coord::Pol_coord()
{
//setting the values to 0
dist=0;
    theta=0;
}

//function for finding the polar coordinates
voidPol_coord::convToPolar(float x,float y)
{
dist=sqrt(pow(x,2)+pow(y,2));
    theta=(atan(y/x)*(180/3.1416));
}

//function for showing the data
voidPol_coord::showdata()
{
cout<<"The polar coordinates are ";
cout<<dist<<", "<<theta<<endl;
return;
}

Explanation:

Create the class Pol_coordwith two floating data members for distance and angle. The constructor is used for assigning these two values.The function convToPolar() is used for converting them into polar coordinates using the following formula:

dist=sqrt(pow(x,2)+pow(y,2));
   theta=(atan(y/x)*(180/3.1416));

b)

Program Plan Intro

Program Plan:

Include the class declaration and implementation in the program.

Create the objects of the class Pol_coordin the main function.

Calculate the polar coordinates using the method convToPolar.

Display the data member values using the function showValues.

Program Description: The purpose of the program is to find the polar coordinate values.

return;
}

intmain()
{
Pol_coord a;
a.convToPolar(9.09326,5.25001);
a.showdata();
return0;
}

Explanation:

The object of the class Pol_coord is created and the function convToPolar ( float, float ) is called with float values and then function showdata() is called for displaying the polar coordinates in the output screen.

Task 2: Comparable Interface and Record (10 Points) 1. You are tasked with creating a Java record of Dog (UML is shown below). The dog record should include the dog's name, breed, age, and weight. You are required to implement the Comparable interface for the Dog record so that you can sort the records based on the dogs' ages. Create a Java record named Dog.java. name: String breed: String age: int weight: double + toString(): String > Dog + compareTo(otherDog: Dog): int > Comparable 2. In the Dog record, establish a main method and proceed to generate an array named dogList containing three Dog objects, each with the following attributes: Dog1: name: "Buddy", breed: "Labrador Retriever", age: 5, weight: 25.5 Dog2: name: "Max", breed: "Golden Retriever", age: 3, weight: 30 Dog3: name: "Charlie", breed: "German Shepherd", age: 2, weight: 22 3.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardises the functions of a telecommunication or computing system into seven distinct layers, facilitating communication and interoperability between diverse network protocols and technologies. Discuss the OSI model's physical layer specifications when designing the physical network infrastructure for a new office.

In a network, information about how to reach other IP networks or hosts is stored in a device's routing table. Each entry in the routing table provides a specific path to a destination, enabling the router to forward data efficiently across the network. The routing table contains key parameters determining the available routes and how traffic is directed toward its destination. Briefly explain the main parameters that define a routing entry.
