- Kindly Solve this C++ question as per the instructions. Thank you for your help! Instructions: 1- Put the class definition in Flight.h and the implementation of the constructors and functions in Flight.cpp Implement the Flight.h and Flight.cpp so that class Flight contains: 4 private instance variables: Name of data type string, which describe the three electric vehicle charger types (AC975, DL521, and AC863). Destination of data type string that shows the final destination of that flight. Hour and Minute of data type int that show the departure time. A default constructor which sets all of the numeric instance variables to zero and the String instance variables to null.
