I'm making a program that uses three classes to calculate the price of carpet in a rectangular room: The price is calculated by multiplying the area of the floor by the price per square foot.

In my RoomDimension class i need two FeetInches objects for length and width. I should use a multiply member function to calculate the area. The class should have a member function that returns the area of the room as a FeetInches object.

In the RoomCarpet class there should be a Room Dimension object as an attribute. There should also be an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet.

The main portion should ask for the dimensions and the price per square foot . It should then display the total cost of the carpet.

Here is my code:

```
// FeetInches.h
#ifndef FEETINCHES_H
#define FEETINCHES_H
class FeetInches
{
private:
int feet;
int inches;
void simplify();
public:
FeetInches(int f = 0, int i = 0)
{
feet = f;
inches = i;
simplify();
}
void setFeet(int f)
{
feet = f;
}
void setInches(int i)
{
inches = i;
simplify();
}
int getFeet() const
{
return feet;
}
int getInches() const
{
return inches;
}
FeetInches operator + (const FeetInches &);
FeetInches operator - (const FeetInches &);
};
#endif
// RoomDimension.h
#include "FeetInches.h"
class RoomDimension
{
private:
int w;
int l;
public:
FeetInches width;
FeetInches length;
};
// RoomCarpet.h
class RoomCarpet
{
private:
public:
};
// FeetInches.cpp
#include <cstdlib>
#include "FeetInches.h"
void FeetInches::simplify()
{
if(inches >= 12)
{
feet += (inches / 12);
inches = inches % 12;
}
else if (inches < 0)
{
feet -= ((abs(inches) / 12) + 1);
inches = 12 - (abs(inches) % 12);
}
}
FeetInches FeetInches::operator - (const FeetInches &right)
{
FeetInches temp;
temp.inches = inches - right.inches;
temp.feet = feet - right.feet;
temp.simplify();
return temp;
}
// RoomMain.cpp
#include "RoomCarpet.h"
#include "RoomDimension.h"
#include "FeetInches.h"
#include <iostream>
using namespace std;
int main()
{
int l;
int w;
cout << "What are the dimensions of the room? ";
cin >>
return 0;
}
```

I know it's not much, but if someone can get me on the right path I would appreciate it. Thanks!
