I need help with coding C++ : 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, and the rate (in gallons per minute) at which the water is draining from 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 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. An example of the program is shown below: Pool data: Length: 30 Width: 15 Depth: 10 Total water in the pool: 0 To completely fill the pool: Enter water fill-in rate: 10 Time to fill the pool is approximately: 56 hour(s) and 6 minute(s) There are three tabs: main.cpp, swimmingPool.h, and swimmingPoollmp.cpp swimmingPool.h: const double GALLONS_IN_A_CUBIC_FEET = 7.48; class swimmingPool  { 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; };
