1. Objective: calculate how many days old you will be on the due date for this lab.

2. Requirements:
--INPUT:
DOB = "July 20, 1994"
dueDate = "September 7, 2014"
yearsOld = 21 (including the current year)

--PROCESSING:
days = 0
leapYears = yearsOld / 4
julianBirthdate = sum of all the days in each month up to month and date of birth
julianDuedate = sum of all days in each month up to month and date of due date
daysToEndOfYear = 365 - julianDuedate
days = days * (365 * yearsOld)
days = days + leapYears
days = days - julianBirthdate
days = days - daysToEndOfYear


--OUTPUT:
objective
author
user instructions (if any)
label1 "Date of birth: "
label2 "Due date: "
label3 "Age in days: "

--DATA:
days-->>total number of days old you are on the date this lab is due (integer)
yearsOld-->>number of years old you are (integer)
leapYears-->>number of leap years from your birth year to this year (integer)
julianBirthdate-->>number of days up to and including your birthday in your birthyear (integer)
daysToEndOfYear-->>number of days from lab due date until the end of the year (integer)
julianDuedate-->>number of days up to due date (integer)
DOB-->>date of birth (text)
dueDate-->>date lab is due (text)


3. Algorithm Instructions
10 output objective
20 output author
30 days = 0
40 yearsOld = 21
50 leapYears = yearsOld / 4
60 julianBirthdate = sum of all the days in each month up to month and date of birth
70 DOB = "July 20, 1994"
80 dueDate = "September 7, 2014"
90 julianDuedate = sum of all the days in each month up to month and date of due date
100 daysToEndOfYear = 365 - julianBirthdate
110 days = days + (365 * yearsOld)
120 days = days + leapYears
130 days = days - julianBirthdate
140 days = days - daysToEndOfYear
150 output label1
160 output DOB
170 output label2
180 output dueDate
190 output label3
200 output days
210 END

4. Test cases
Test Case #1: DOB = 7/20/1994, dueDate = 9/7/2014

130 days = 7670 - 201 = 7469
