Chapter – 5. CONSTRUCTORS & DESTRUCTORS

Public Members:

• A constructor to assign initial values as follows:
TCode with the word “NULL”
No _of_ Adults as 0
No_ of_Children as 0
Distance as 0
TotalFare as 0

• A function AssignFare() which calculates and assigns the value of the data member Totalfare as follows For each Adult
Fare (Rs) For Kilometers 500 >=1000
300 <1000 & >=500
200 <500

For each Child the above Fare will be 50% of the Fare mentioned in the above table
For Example:

If Distance is 750, No_of_adults =3 and
No_of_Children =2
Then TotalFare should be calculated as
Num_of _Adults *300+ No_of_Children *150 i.e., 3*300+ 2 *150 =1200

• A function EnterTour() to input the values of the data members T_Code, No_of_Adults, No_of_Children and Distance ; and invoke the AssignFare() function.

• A function ShowTravel() which displays the content of all the data members for a Travel.
