Day of the Week (Due 03 July 2013)

In this program you will prompt the user to enter the day, month, and year. Your program will print out the day of the week for that date. Here is a sample output for the program:
Enter year: 1960
Enter month: 12
Enter day: 12

The day is Monday.

Assume that all the input values will be positive integers. The day will be in the range 1 through 31. The month will be in the range 1 through 12 where 1 is for January and 12 is for December. The year will be a four digit number in the range 1900 through 2100.

Your program will check the following: All of the ranges are inclusive. You will first prompt the user to enter the year and then check whether the year is in the range specified. If it is not, then you will keep prompting the user to enter the correct year. After that you will prompt the user to enter the month and run a similar check. Lastly, you will prompt the user to enter the day and run a check. For example, the input 29, 2, 2012 is valid, but the input 29, 2, 1900 is not, because 2012 is a leap year and 1900 is not a leap year.

This algorithm was developed by Rev. Zeller. Let us define the quantities a, b, c, and d as follows:

Important: In our calendar, the year begins in January and ends in December. In the calendar, used in the algorithm, the year begins in March and ends in February. Your program should internally make the adjustment and not expect the user to know this. For example, if in our calendar we have January 2009 (month = 1 and year = 2009), the program will make the adjustment so that month = 11 and year = 2008. If you do not make the adjustment you will not get the right result.

For example, 31 July 1929, gives a = 5, b = 31, c = 29, and d = 19. Similarly, 3 January 1988, gives a = 11, b = 3, c = 87, and d = 19.

Now compute the following quantities:

r gives the day of the week. r = 0 represents Sunday, r = 1 represents Monday, and so on.
