Answer to Question #198906 in C++ for anuj

Question

a class FlightData in C++ with private data members as fltNum (storing flight number), fltDest (to store destination in km’s), fltDist (to store total distance), ppUnit(to store price (in float) of fuel per unit), totalCost (to store flight running cost). A member function calCost() to find out the flight running cost and store it in totalCost

Distance

Fuel Required(in Units)

Base Charges

<=500

1000

2865

more than 500 and <=1500

3000

3875

more than 1500

4000

4885

totalCost=Base Charges + (Distance*fuel required*price per unit).

Store values of base charges, fixed for every object of class using 3 integer data members having values mentioned in table above. Public members of class are, a function to allow user to enter all data members value and a function to display all flight information with total flight running cost calculated using calCost function. Create an object of class entering all details calculating and displaying flight running cost for it.
