Part Two: Programming Questions (3 x 20 marks)
1. (20 marks) By definition the Greatest Common Divisor (GCD) of two integers M and N is an integer that is the greatest among the numbers that can divide both M and N. Write a web page with embedded PHP scripts that can find out the GCD of M and N (both are non-zero), which are input from the user. The found GCD shall be displayed in the HTML5 table along with the M and N, as well as all other common divisors for people to check that the number is indeed a GCD. In the form for users to input M and N, JavaScript should be used to
validate the input to make sure it is a non-zero integer number.
2. (20 marks) Create an XML document that marks up the structure of COMP 466, up to
sections, and then create an XML schema to describe the structure of your XML document.
3. (20 marks) Using the server-side programming language you chose for your third assignment (ASP.NET in C#, ASP.NET in VB, or JSF), write a web page that will allow users to order computers and related parts. The order form should have input fields for user contact information, including name, mailing address, email, and telephone number, as well as a list of computers and a list ofparts. The user inputs need to be validated, and the total cost of the order should be dynamically shown whenever a selection is made or changed. Once the form is submitted, the user inputs should be displayed in a well laid-out format including the IP address of the user’s computer.
