The assignment problem is straightforward. All necessary details have been supplied. The solution of theproblem will be straight line code which will use the programming concepts and strategies covered in
Workshops 1-3. The subgoals are:
- Understanding values, variables and constants, Objects, Operations, and Functions
- The mechanics of editing, interpreting, building and running your program
- Testing your program
- Commenting your source code
- Becoming confident and comfortable with programming in small problems
Constants and Variables
Within the script section, create constants and variables following professional conventions and initialise them using right values. Some constants and variables have been suggested in the following tables. You should create more when necessary.
1. Create a Date object for the date of birth by using the variables created previously.
• Use one prompt function to input the name of user as Figure 2.
CSC1401 Assignment 1 Specification – Days-From-Birth 3
Figure 2: Illustration of the four inputs
• Use another three prompt functions to input the year, month, day of the birth one by one and then transfer them to the Date constructor.
• Mind the order of arguments sent to the constructor;
• Note that month numbers in Date constructor begin at 0 for January (‘1’ entered in prompt function), 1 for February (‘2’ entered in prompt function), and so on;
2. Create a Date object for the current time.
• No arguments need to be supplied to the constructor.
3. Calculate the difference between the current time and the birth time (assume it is the startingtime 0:00:00 a.m. on the Date of birth):
• Use the getTime() member function to get a Date object’s time value in milliseconds
• Deduct the time value of current time by using the value of event time.
4. Calculate the number of days from the birth:
• Divide the time value difference by the number of milliseconds in a day.
• Use the Math.floor() function to reduce the result number to an integer.Presentation
Figure 3 shows a sample output when running the “Days-From-Birth” program. Note that
the information should be displayed using the alert() function;
CSC1401 Assignment 1 Specification – Days-From-Birth 4
wherever possible you should use variables in expressions instead of explicit values (e.g., literalsand numbers), for example, using the variable created for the user name instead of a string valueof “Lily”; “XXXX” is the number of days from the date of birth.

Test your program by enter your own date of birth to see whether the outcome is correct or not.Non-functional Requirements
Structure of the Source Code
(a) Constants;(b) Variables and objects (declared and initialised);(c) Other statements.Comments
You are required to add at least three comments to the source code. Do not comment every single line, instead, comment on blocks of code with a common purpose. Do not simply translate the syntax into English for comments, instead, describe the purpose ofblocks of code.SubmissionWhat You Need to Submit – Two Files
For a complete submission you need to submit two files as specified below.CSC1401 Assignment 1 Specification – Days-From-Birth 5The assignment submission system will accept only the files with extensions specified in this section.1. Statement of Completeness in a file saved in .pdf format in 200-300 of your own words describes: The state of your assignment, such as, any known functionality that has not been implemented,etc. (It is expected that most people will implement all of the functionality of this assignment.) Problems encountered, such as, any problems that you encountered during the assignment workand how you dealt with them; Reflection, such as, any lessons learnt in doing the assignment and suggestions to futureprogramming work.2. The program in a file saved with an .html extension contains the source code implementedfollowing the functional and non-functional requirements.Late Submission and Extension RequestPlease refer to USQ Policy Library - Assessment Procedure for information on the late submission policyand USQ Policy Library - Assessment of Compassionate and Compelling Circumstances Procedure forconsiderable special circumstances in extension request.The Extension Request Form is available on the course’s StudyDesk. Should you need to request anextension please fill the form and email it to the Course Examiner with supportive documents (e.g.,medical certificate or endorsement letter from supervisor in workplace) prior to the due date. Please notethat any requests without supportive documents will be declined straight way withoutconsideration.
