C++ Classes and Objects

Subtask 7

Define a class with name Airport with following members:

• a private attribute with the name of the airport as C++ string.
• a private attribute with name slot as array of pointers to flights (subtask 5) with 24 rows (for the hours of a day) and 60 columns (for the minutes of each hour of a day), getting initialised by null pointers (i.e. maximum 24*60 starts and landings each day; due to turbulences of the air and for security reasons at least one minute pause has to be inbetween two starts). In this array pointers to scheduled landings or starting flights in each minute of a day shall get stored.
• definition of a public constructor with a name as parameter to initialise the respective attribute.
• definition of a public destructor deleting the whole pointer array with all flight objects on heap.
• definition of a public function with name schedule having a LocalTime and a pointer to a flight as parameters without return value and storing the flight at the scheduled time slot.
• definition of a public function with name comment with a LocalTime and a string as parameters having no return value and storing the string as comment of the flight at this scheduled time slot.
• definition of a public function with name delay with two LocalTime parameters having no return value and storing the time in second parameter in the flight object at the scheduled time given in the first parameter.
• definition of a public function with name print with one parameter of above enumeration type from subtask 2 for arrivals or departures without return value. In its body write a table of all stored arriving flights or starting flight given by the parameter value (see example below).
