Question

In this assignment, you’ll practice communicating with input and output files and organizing string data. Your program will need to do the following:
1. Read in a list of calendar reminders from a file called “reminders.txt” (they will be stored initially as “mm/dd reminder_string”…e.g., “04/19 Exam 2 in ECE 285”). Store these strings in a two dimensional array. There will be no more than 30 reminders in the file, and each reminder will be less than 30 characters. You can use the read_line() function from the remind.c program on p295 if you like, and the code for main on that page will be a helpful reference (do not copy it!).
2. The reminders will be arranged and printed to two different files. The first file should be called “Dates.txt”, and you should print the list of reminders in order according to month, then day. The second file should be called “List.txt”, and you should print the list of reminders in two columns (Reminder and Date) in alphabetical order as “reminder_string mm/dd” (e.g., Exam 2 in ECE 285 04/19).
Since nothing is printed to the screen here, I can’t post screenshots. However, I’ll soon post an input text file, “reminders.txt” on eLearning which you can use to test your program. You can use any libraries you’d like (the string library is especially useful), and all of this can be in one big *.c file.
