Calendar Cum Schedular
The program shows the calendar for the given month and year. It also has an additional functionality. It shows the notes for any particular day and highlights the current date. It can be used as appointment reminder.
It starts by taking input from the user. User has to provide the year and month for which he wants to see the calendar. After this the program checks if the entered year is a leap year or not. Then it calculates the number of leap years occurred from 1900 to the entered year. This is used to calculate the total number of days from 1900 to date. This number is divided into 7 days of week. This is how we get the first day of the month. Then the calendar is printed and then the current date is highlighted.
The user is shown the notes for the current date. He can navigate through the dates using arrow keys on the NUMERIC KEYPAD. Pressing Enter key the user can enter notes. Using UP/DOWN arrow keys the year can be changed. Using RIGHT/LEFT arrow keys the month changes.
Rest of the program is self-explanatory.
