Question

I need help making this in C++ Asap!

If you feel information is missing, or provided information is incorrect, make assumptions but clearly state your assumptions.

You should NEVER use global variables. Other than the main() function, there should be no global functions in your code. Other than the test() function not other function needs to be a static function in this problem.

Let us say you find a consulting opportunity for a regional real-estate company that wants you to write a class to do statistical analysis that also keeps track of all the houses sold in your area. There are currently 100 houses in the region of their operation and they are never are expected to store more than 200 sales.

They want you to store the sales price in a local array of this class as soon as the house is sold. Only sale price is stored, the address or the date of sale or any other data is not stored by this class.

They also want to be able to determine the maximum price of all the houses sold based on the current entries in this array.

You have to write a class that provided following functions:

void addHouseSale(double salePrice); //Adds the house sale to the sold[] array.

double calculateMaximumPrice();

The class must implement an array called "sold". You will determine the capacity of the array need in your program and what you need to maintain how many houses have been sold so far.

(You have to make the decision on how many data members you need in addition array. No! this problem does not need dynamic memory allocation).

Your program will assume that the history is started fresh, every time you execute the program. That is: the first call to addHouseSale(double salePrice) will make the first entry into the array.

Please implement a print() function that prints all of the data members of the class in a friendly manner.

Please implement a static test() function that tests all other functions, and at least 5 new entries into the array.

Please make sure that you use "Preformatted" style rather than "Paragraph" for the entire code and ensure it is readable and properly indented.

You have to provide

You are not required to show code separated by files. You can paste all of your code in the following edit box (using "Preformatted" style).

complete contents of the .h file: [18]

all system includes [1]

all #define's you need [1]

class declaration that includes:

Constructor [2]

all function declarations (including test, and print functions) [8]

the array declaration [4]

any other variables you need to make this work [2]

complete contents of the .cpp file that includes complete definitions (implementation) of: [57]

Constructor  

addHouseSale(double salePrice) function [5 points]

calculateMaximumPrice() function [20 points]

print() function [10 points]

test() function [20 points]

main function that simply calls the test() function. [2 points]

Answer 1

// houseSale.h file containing the system includes, # defines and class declaration

#ifndef HOUSESALE_H_

#define HOUSESALE_H_

// system includes

# include<iostream>

# define MAX_SALE 200 // define maximum number of sales

using namespace std;

// class defining the sales

class HouseSale{

               private :

                              double sold[MAX_SALE]; // array storing the sale prices. Maximum size :00

                              int sales; // variable to hold the number of sales

               public:

                              // constructor

                              HouseSale();

                              void addHouseSale(double salePrice); //Adds the house sale to the sold[] array.

                              double calculateMaximumPrice(); // calculate and return the maximum sale price

                              void print(); // print the variables of the class

                              static void test();// test the functions of the class

};

// end of HouseSale class

#endif /* HOUSESALE_H_ */

// end of houseSale.h

// houseSale.cpp implementing the class HouseSale and the main function

# include "houseSale.h"

// implementation of class HouseSale

HouseSale::HouseSale()

{

               sales=0;

}

void HouseSale::addHouseSale(double salePrice)

{

               if(sales < MAX_SALE)

               {

                              sold[sales] = salePrice;

                              sales++;

               }

}

double HouseSale::calculateMaximumPrice()

{

               double max =0;

               if(sales > 0)

                              max = sold[0];

               for(int i=1;i<sales;i++)

               {

                              if(sold[i] > max)

                                             max = sold[i];

               }

               return max;

}

void HouseSale::print()

{

               cout<<"\n Number of sales : "<<sales;

               if(sales > 0){

                              cout<<"\n Sales details : ";

                              for(int i=0;i<sales;i++)

                                             cout<<"\n Sale price "<<(i+1)<<" : "<<sold[i];

               }

}

void HouseSale::test()

{

               HouseSale hSale;

               hSale.addHouseSale(200.25);

               hSale.addHouseSale(450.5);

               hSale.addHouseSale(600);

               hSale.addHouseSale(500.85);

               hSale.addHouseSale(760);

               hSale.print();

               cout<<"\n Maximum sale price :"<<hSale.calculateMaximumPrice();

}

int main()

{

               HouseSale::test(); // call the test function of HouseSale class

               return 0;

}

// end of houseSale.cpp

Output:

Number of sales5 Sales details: Sale price 1 200.25 Sale price 2 : 450.5 Sale price 3 : 600 Sale price 4 : 500.85 Sale price 5 : 760 Maximum sale price:760 5
