Question

Using C++

Create a header file that defines a class called Building. The variables: the width, the length, and the height. There should be functions to set the width and height, to get the width and height, and to get the volume of the building. Note: each floor of the building is ten feet high. So, also get the number of floors in the building.

Call the header file in a program, also called building. Do not accept invalid input. Display the volume of the building and the number of floors. Submit the header file and the .cpp file.

---------------------------------------------------------------

note :: save both the files with the same name and in the same folder with the extension .h and .cpp.

---------------------------------------------------------------------------------------

// Building.h

class Building
{
// class variables
private:
float width;
float length;
float height;
// class member functions
public:
void setWidth(float);
void setLength(float);
void setHeight(float);
float getWidth();
float getLength();
float getHeight();
float getVolume();
};
// function definitions
// setters
void Building::setWidth(float w)
{
width=w;
}
void Building::setLength(float l)
{
length=l;
}
void Building::setHeight(float h)
{
height=h;
}
// getters
float Building::getWidth()
{
return width;
}
float Building::getLength()
{
return length;
}
float Building::getHeight()
{
return height;
}
float Building::getVolume()
{
// finding volume and return the result
float volume = width * length * height;
return volume;
}
--------------------------------

// Building.cpp
#include "Building.h" // header in local directory
#include <iostream> // header in standard library
#include<conio.h> // optional header for getch() function
#include<cmath> // for floor()   

using namespace std;

int main()
{
// object of the class Building
Building b1;
// declarations
float width, height, length, volume, floors;
cout << "Input Width: ";
cin>>width;
cout << "Input Length: ";
cin>>length;
cout << "Input Height: ";
cin>>height;
// validation
if(width <=0 || length <=0 || height <=0)
{
// if invalid input
cout << "\n\nInvalid Input!!!";   
}
else
{
// call the member functions using class object
b1.setWidth(width);
b1.setLength(length);
b1.setHeight(height);
volume = b1.getVolume();
// print the volume
cout << "\n\nVolume : " << volume;

// get the building height
height = b1.getHeight();
// as each floor is 10ft height
floors = height / 10;
// apply floor function to it to get the whole number as floors count
floors = floor(floors);
cout << "\nNumber of floors in the Building: "<<floors;
}
  
getch();
return 0;
} // main ends
