Develop and demonstrate a XHTML document that illustrates the use external style
sheet, ordered list, table, borders, padding, color, and the <span> tag.
Develop and demonstrate a XHTML file that includes Javascript script for the
following problems:
a) Input: A number n obtained using prompt.
Output: The first n Fibonacci numbers.

3

b) Input: A number n obtained using prompt.
Output: A table of numbers from 1 to n and their squares using alert.
Develop and demonstrate a XHTML file that includes Javascript script that uses
functions for the following problems:
a) Parameter: A string
Output: The position in the string of the left-most vowel.

4

6

b) Parameter: A number
Output: The number with its digits in the reverse order.
a) Develop and demonstrate, using Javascript script, a XHTML document that
collects the USN ( the valid format is: A digit from 1 to 4 followed by two upper-case
characters followed by two digits followed by two upper-case characters followed by
three digits; no embedded spaces allowed) of the user. Event handler must be
included for the form element that collects this information to validate the input.
Messages in the alert windows must be produced when errors are detected.
b) Modify the above program to get the current semester also (restricted to be a
number from 1 to 8)
a) Develop and demonstrate, using Javascript script, a XHTML document that
contains three short paragraphs of text, stacked on top of each other, with only
enough of each showing so that the mouse cursor can be placed over some part of
them. When the cursor is placed over the exposed part of any paragraph, it should
rise to the top to become completely visible.
b) Modify the above document so that when a paragraph is moved from the top
stacking position, it returns to its original position rather than to the bottom.
a) Design an XML document to store information about a student in an engineering
College affiliated to VTU. The information must include USN, Name, Name of the
College, Brach, Year of Joining, and e-mail id. Make up sample data for 3 students.
Create a CSS style sheet and use it to display the document.
b) Create an XSLT style sheet for one student element of the above document and
use it to create a display of that element.

a) Write a Perl program to accept the User Name and display a greeting message
randomly chosen from a list of 4 greeting messages.

and to display this count of visitors, with proper headings.
Write a Perl program to display a digital clock which displays the current time of the
server.
Write a Perl program to insert name and age information entered by the user into a
table created using MySQL and to display the current contents of this table.
Write a PHP program to store current date-time in a COOKIE and display the ‘Last
visited on’ date-time on the web page upon reopening of the same page.
Write a PHP program to store page views count in SESSION, to increment the count
on each refresh, and to show the count on web page.
Create a XHTML form with Name, Address Line 1, Address Line 2, and E-mail text
fields. On submitting, store the values in MySQL table. Retrieve and display the data
based on Name.
Using PHP and MySQL, develop a program to accept book information viz. Accession
number, title, authors, edition and publisher from a web page and store the
information in a database and to search for a book with the title specified by the
user and to display the search results with proper headings.
