Swimming pool management – (c++)in this programming exercise you will create a simple swimming management program according to the following customer specifications: - write the definition of a class swimmingpool, to implement the properties and functions of a swimming pool. the pool must be a rectangular shaped of any dimension. (20% the class should have the instant variables to store the length (in feet), width (in feet), depth (in feet), amount (in cubic feet), of water in the pool, the rate (in gallons / minute), at which the water is draining from the pool.- must add the swimmingpool constructor(s) and destructor member functions. (10%)- add appropriate accessor and mutator member functions.(10%)- add member functions to do the following: (40% determine the amount of water needed to fill an empty or partially filled determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of allow adding or subtracting one or more pools (add by adding lenghs, widths and depths, rates and amount – subtract by subtracting lengths, widths, and depths, rates and amount).add a static property (data member) to count the number of swimming pools created and static member function to report this count.(20%)note: the amount of gallons in a cubic feet is 7. use the following driver program to test your class:
