Question

1. Write the definition of a class, swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool.

Add appropriate constructors to initialize the instance variables. Also add member functions, to do the following: Determine the amount of water needed to fill an empty pool; the time needed to completely fill the pool; add water for a specific amount of time.

run:

Pool data:

  Length: 30.0

  Width: 15.0

  Depth: 10.0

  Total water in the pool: 0.0

To completely fill the pool:

  Enter water fill in rate (in gallons per minutes): 100

Time to fill the pool is appriximately: 5 hour(s) and 37 minute(s).

run:

Pool data:

  Length: 30.0

  Width: 15.0

  Depth: 10.0

  Total water in the pool: 0.0

To completely fill the pool:

  Enter water fill in rate (in gallons per minutes): 10

  Time to fill the pool is appriximately: 56 hour(s) and 6 minute(s).

BUILD SUCCESSFUL (total time: 14 seconds)

SwimmingPool.h

#ifndef SWIMMINGPOOL_H
#define SWIMMINGPOOL_H

class SwimmingPool
{
public:
SwimmingPool();
SwimmingPool(double, double, double,double);
double waterAmountNeeded();
double calculateTime();
double addWater();
private:
double length;

#endif // SWIMMINGPOOL_H

SwimmingPool.cpp

#include "SwimmingPool.h"

// Default Constructor
SwimmingPool::SwimmingPool(){

}

// Parameterized constructor
SwimmingPool::SwimmingPool(double length,double height,double depth,double rate):length(length),height(height),depth(depth),rate(rate){}

// Calculate and return water needed in gallons
double SwimmingPool::waterAmountNeeded()
{
return length*height*depth*7.5;

// Calculate time in minutes and convert into
double SwimmingPool::calculateTime(){
double minutes = waterAmountNeeded()/rate;
return minutes;
}

// Add water
double SwimmingPool::addWater(){
return rate*calculateTime();
}

main.cpp

#include <iostream>

using namespace std;

int main()

// Take inputs

cout<<"\tTotal Water in the pool: 0.0"<<endl;
cout<<"To completely fill the pool:"<<endl;
cout<<"\tEnter water fill in rate (in gallons per minutes):";

// Create object of swimming pool
SwimmingPool s(length,height,depth,rate);

// Calculate time and convert into minutes and hours
double time = s.calculateTime();
int minutes = (int)time;
int hours = minutes/60;
minutes = minutes - hours*60;
cout<<"Time to fill the pool is approximately: "<<hours<<" hour(s) and "<<minutes<<" minute(s)."<<endl;
return 0;

}
