Write a program that will provide such a service. The input will specify the year for which the calendar is relevant (in the range 1901 to 1999). Bear in mind that, within the range specified, all years that are divisible by 4 are leap years and hence have an extra day (February 29th) added. The output will specify “today’s” date, a list of forthcoming events and an indication of their relative importance.
An anniversary line will consist of the letter `A’; three integer numbers (D, M, P) representing the date, the month and the importance of the event; and a string describing the event, all separated by one or more spaces. P will be a number between 1 and 7 (both inclusive) and represents the number of days before the event that the reminder service should start. The string describing the event will always be present and will start at the first non-blank character after the priority.
A date line will consist of the letter `D’ and the date and month as above.
All anniversary lines will precede any date lines. No line will be longer than 255 characters in total. The file will be terminated by a line consisting of a single #.
The output should specify the date of the event (D and M), right justified in fields of width 3, and the relative importance of the event. Events that happen today should be flagged as shown below, events that happen tomorrow should have P stars, events that happen the day after tomorrow should have P-1 stars, and so on. If several events are scheduled for the same day, order them by relative importance (number of stars).
If there is still a conflict, order them by their appearance in the input stream. Follow the format used in the example below. Leave 1 blank line between blocks.
