/* Slip no : 21_2 Imagine a ticket Selling booth at a fair. People passing by are requested to purchase a ticket. A ticket is priced as Rs. 5/- . The ticketbooth keeps the track of the number of peoples that have visited the booth and of the total amount of cash collected.

Create a class ticketbooth that contains No_of_people_visited, Total_Amount_collected. Write C++ program to perform following functions:

To assign initial values.

To increment the No_of_people_visited  if visitors have just visited the booth.

To increment the  No_of_people_visited  and Total_amount_collected if tickets have been purchased.

To display both totals     */
