Chapter – 5. CONSTRUCTORS & DESTRUCTORS

Private Members:

Travelcode	of type long
Place	of type character array(string)
Number_of_travellers	of type integer
Number_of_buses	of type integer

Public Members:

* A constructer to assign initial values of TravelCode as 201, Place as “Nainital”, Number_of_travellers as 10, Number_of_buses as 1

* A function NewTravel() which allows user to enter TravelCode, Place and Number_of travelers. Also, assign the value of Number_of_buses as per the following conditions:

Number_of_travellers	Number_of_buses
Less than 20	1
Equal to or more than 20 and less than 40	2
Equal to 40 or more than 40	3

* A function ShowTravel() to display the content of all the data members on the screen.
