03-16 Lab exercise 1: Printing a One-Month Reminder List

Question

The remind.c program prints a one-month list of daily reminders.

• The user will enter a series of reminders, with each prefixed by a day of the month.

• When the user enters 0 instead of a valid day, the program will print a list of all reminders entered, sorted by day. Use LIFO ( Last In First Out) for reminders in the same day.

• Ignore a reminder if the corresponding day is negative or larger than 31

Example input:

24 Susan's birthday
5 9:00 - Meeting with Daniel
5 7:00 - Dinner with Marge and Russ
26 Movie - "Chinatown"
7 10:30 - Dental appointment
12 15:00 Movie - "Dazed and Confused"
5 Saturday class
12 Saturday class
12 20:00 - Theatre - "Hamlet"
0

Example output:

Day Reminder
  5 Saturday class
  5 7:00 - Dinner with Marge and Russ
  5 9:00 - Meeting with Daniel
  7 10:30 - Dental appointment
 12 20:00 - Theatre - "Hamlet"
 12 Saturday class
 12 15:00 Movie - "Dazed and Confused"
 24 Susan's birthday
 26 Movie - "Chinatown"
