Question

I am learning C++ and having difficulties understanding the concepts from my reading. A project that is supposed to help me learn deconstructors and constructors has me confused.

There are 3 different programs that are supposed to be used together. I am newer to the concept of adding .h to the end of a c++ file.

The main.cpp file is empty. In the file swimmingPool.h this code is provide already:

const double GALLONS_IN_A_CUBIC_FEET = 7.48;

class sPool

{

public:

void set(double l = 0, double w = 0, double d = 0,

double fi = 0, double fo = 0, double wInPool = 0);

void setLength(double l);

void setWidth(double w);

void setDepth(double d);

void setWaterFlowRateIn(double fi);

void setWaterFlowRateOut(double fo);

void addWater(double time, double fillRate);

void drainWater(double time, double drainRate);

double poolTotalWaterCapacity();

double getLength();

double getWidth();

double getDepth();

double getWaterFlowRateIn();

double getWaterFlowRateOut();

double getTotalWaterInPool();

int timeToFillThePool();

int timeToDrainThePool();

double waterNeededToFillThePool();

swimmingPool(double l = 0, double w = 0, double d = 0,

double fi = 0, double fo = 0, double wInPool = 0);

//Constructor

private:

double length;

double width;

double depth;

double waterFlowInRate;

double waterFlowOutRate;

double amountOfWaterInPool;

};

The third, and dumbfounding file to me, is sPoollmp.cpp; which is also empty.

The question asks me to write a definition of a class swimmingPool so I can implement the properties of a swimming pool.

This class should have instance variables to store length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Appropriate constructors to initialize the instance variables will be needed.

Also, I need to add member functions to do the following:

Determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference.

Write a program to test your swimmingPool class.

Can someone help me understand this concept I am trying to learn?
