int price	to store the printed price of the book
int day	to store the number of days for which fine is to be paid
double fine	to store the fine to be paid

Member functions	Purpose
void input()	To accept the name of the book and printed price of the book
void cal()	Calculates the fine to be paid
void display()	Displays the name of the book and fine to be paid

Write a program to compute the fine according to the given conditions and display the fine to be paid.

Days	Fine
First seven days	25 paise per day
Eight to fifteen days	40 paise per day
Sixteen to thirty days	60 paise per day
More than thirty days	80 paise per day
