Question

could you solve this in C++ please

2. (25 marks) Define a class called "House", that represents the information of a house. A House is defined with these attributes: age (int), type (string) (Detached, Semi-Attached, Attached), rooms (int) and cost (double). Functions of the House class must perform the following operations: • Return the house age • Modify the house age • Return the house type • Return the number of rooms • A function called estimate Price() that returns cost of a house based on type and age. An attached house, costs $100,000, appreciates 1% every year in first five years and 2% every year afterwards. A Semi-detached house, costs $150,000, appreciates 2% every year in first five years and 3% every year afterwards. A Detached house, costs $200,000, appreciates 2% every year in first five years and 2% every year afterwards. Test your class by prompting the user to enter information about two different houses. Create two objects of the class House with the information entered by the user, and finally, test the member functions of the class. Also calculate the estimated price of houses given type and age (include 1 attached and 1 detached) Deliverables: • A file called house.h that contains the specification of the class. • A file called house.cpp that contains the implementation of the member functions of the class. • A file called testhouse.cpp that contains the main function.

Answer 1

Points to consider:

1. House.h file which contains the declaration of all the variables and the functions.
2. House.cpp file contains the definition of all the functions.
3. testhouse.cpp is the file that uses the functions of the class.

Code

house.h

#include<string>
using namespace std;
class House{
   int age;
   string type;
   int rooms;
   double cost;
   public:
       int getAge();
       void setAge(int age);
       string getType();
       int getRooms();
       void estimatePrice(int age, string type);
       void printHouse();
       House(int age, string type, int rooms){
            this->age = age;
           this->type = type;
           this->rooms = rooms;
       }
};

house.cpp

#include "house.h"
using namespace std;

int House :: getAge(){
   return age;
}
void House :: setAge(int age){
   this->age = age;
}
string House :: getType(){
   return type;
}
int House :: getRooms(){
   return rooms;
}
void House :: estimatePrice(int age, string type){
   double cost = 0;
   if(type.compare("Attached") == 0){
       cost = 100000;
       for(int i = 1;i<=age;i++){
           if(i<=5){
               cost = cost*1.01;
           }else{
               cost = cost*1.02;
           }
       }
   }else if(type.compare("Semi-Attached") == 0){
       cost = 150000;
       for(int i =1;i<=age;i++){
           if(i<=5){
               cost = cost*1.02;
           }else{
               cost = cost*1.03;
           }
       }
   }else{
       cost = 200000;
       for(int i = 0;i<=age;i++){
           cost = cost*1.02;
       }
   }
   this->cost = cost;
}
void House::printHouse(){
   cout<<"House Details: "<<"Age: " << this->age <<" Rooms: " << this->rooms << " " << " Type: " << this->type <<endl<<"estimated Cost: " << this->cost;
   cout<<endl;  
}

testhouse.cpp

#include<iostream>
#include "house.cpp"
using namespace std;
int main(){
   House house1(2, "Attached", 10);
   House house2(6, "Detached", 6);
   house1.estimatePrice(house1.getAge(), house1.getType());
   house2.estimatePrice(house2.getAge(), house2.getType());
   house1.printHouse();
   house2.printHouse();
}
