Question

1. An airplane model can be described (highly oversimplified) by the following attributes • model: string • emptyweight: double • number of seats: int • fuel Consumption: double

a) Define a class AirplaneModel with the attributes defined above.

b) Your class should contain the following member functions: • A default constructor that initializes the class’s attributes.

• A constructor that sets the attributes. • string getName() to get the model’s name

• double getEmptyWeight() to get the model’s empty weight •

int getSeats() to get the number of seats

• double getFuelConsumption() to get the fuel consumption

• setName(string) to set the model’s name •

setEmptyWeight(double) to set the model’s empty weight •

setFuelConsumption(double) to set the fuel consumption •

setSeats(int ): to set the number of seats to an airplane.

• AddSeats(int ): to add seats to an airplane of seats.

c) Write the implementation of the above functions and include them in a C++ file using only iostream library

d) Develop an application that uses the Airplane class and perform the following tasks:

• Construct an object called Boeing737 that is initialized with the following data:

modeltobegiven737

emptyweight:41145Kg

numberofseats:200

fuelConsumption:750gallons/hour

• Construct another object call AirbusA320 and get all its data from the user and then set the values read from the input using the appropriate mutators.

Assume the following values of the Airbus object:

modeltobegivenA320

emptyweight:37230Kg

numberofseats:220

fuelConsumption:1073gallons/hour •

Display a report about the two airplane objects • Add 50 seats to the two airplane objects •

Compute the increased fuel consumption as a result of increasing the number of seats using this equation (fuel Consumption/number of seats)* the new number of seats, for the two objects

• Display the number of seats and the new fuel consumptions of the two the Boeing 737 and the Airbus A320

Code:

#include<iostream>
using namespace std;

{
   string model;
   double emptyWeight;
   int numberOfSeats;
   double fuelConsumption;
   public:
   AirplaneModel()//default constructor
   {
      
   }
   AirplaneModel(string model, double emptyWeight, int numberOfSeats, double fuelConsumption)//parameterised constructor
   {
       this->model=model;this->emptyWeight=emptyWeight;this->numberOfSeats=numberOfSeats;this->fuelConsumption=fuelConsumption;
   }
   string getName()//get methods
   {
       return model;
   }
   double getEmptyWeight()
   {
       return emptyWeight;

   void setName(string name)//set methods

   void setEmptyWeight(double wt)
   {

   void setFuelConsumption(double fuel)
   {

   }
   void setSeats(int sts)
   {
       numberOfSeats=sts;
   }
   void AddSeats(int sts)
   {
       numberOfSeats+=sts;
   }
};
int main()
{
   AirplaneModel Boeing737("737", 41145, 200, 750);//declared
   AirplaneModel AirbusA320;
   AirbusA320.setName("A320");AirbusA320.setEmptyWeight(37230);//setting explicitly
   AirbusA320.setSeats(220);AirbusA320.setFuelConsumption(1073);
   cout<<"Boeing737"<<endl;
   cout<<"No. of seats: "<<Boeing737.getSeats()<<endl;

   Boeing737.AddSeats(50);
   AirbusA320.AddSeats(50);
   Boeing737.setFuelConsumption(Boeing737.getSeats()*Boeing737.getFuelConsumption()/(Boeing737.getSeats()-50));//increasing fuel
   AirbusA320.setFuelConsumption(AirbusA320.getSeats()*AirbusA320.getFuelConsumption()/(AirbusA320.getSeats()-50));
   cout<<"Increased fuel consumption of AirbusA320: "<<AirbusA320.getFuelConsumption()<<endl;
   cout<<"Seats: "<<AirbusA320.getSeats()<<endl;

   return 0;
}
