Imagine a ticket selling booth at a fair. People passing by are requested to purchase a ticket. A ticket is priced at Rs. 2.50. The booth keeps track of the number of people that have visited the fair and of the total amount of money collected. Model this ticket selling booth with a class tick. Include a program to rest this class

#include<iostream.h>

#include<conio.h>

#include<process.h>

class tick

{

               int nop;

               void inc();

               void display();

               void displaynop();

};
