1. Write a JavaScript to design a simple calculator to perform the following operations: sum,
product, difference and quotient.
2. Write a JavaScript that calculates the squares and cubes of the numbers from 0 to 10and
outputs HTML text that displays the resulting values in an HTML table format.
3. Write a JavaScript code that displays text “TEXT-GROWING” with increasing font size in
the interval of 100ms in RED COLOR, when the font size reaches 50pt it displays “TEXT-
SHRINKING” in BLUE color. Then the font size decreases to 5pt.
4. Develop and demonstrate a HTML5 file that includes JavaScript script that uses functions for
the following problems:
a) Parameter: A string
b) Output: The position in the string of the left-most vowel
c) Parameter: A number
d) Output: The number with its digits in the reverse order
5. Design an XML document to store information about a student in an engineering college
affiliated to VTU. The information must include USN, Name, and Name of the College,
Branch, Year of Joining, and email id. Make up sample data for 3students. Create a CSS style
sheet and use it to display the document.
6. Write a PHP program to keep track of the number of visitors visiting the web pageand to
display this count of visitors, with proper headings.
7. Write a PHP program to display a digital clock which displays the current time of theserver.

8. Write the PHP programs to do the following:
a) Implement simple calculator operations.
b) Find the transpose of a matrix.
c) Multiplication of two matrices.
d) Addition of two matrices.
9. Write a PHP program named states.py that declares a variable states with value “Mississippi
Alabama Texas Massachusetts Kansas". write a PHP program that does the following:
a) Search for a word in variable states that ends in xas. Store this word in element0 of a list
named states List.
b) Search for a word in states that begins with k and ends in s. Perform a case-insensitive
comparison. [Note: Passing re.Ias a second parameter to method compile performs a
case-insensitive comparison.] Store this word in element1of states List.
c) Search for a word in states that begins with M and ends in s. Store this word in element 2
of the list.
d) Search for a word in states that ends in a. Store this word in element 3 of the list.
10. Write a PHP program to sort the student records which are stored in the database using
selection sort.

Study Experiment / Project:
Develop a web application project using the languages and concepts learnt in the theory and
Exercises listed in part A with a good look and feel effects. You can use any web technologies
and frameworks and databases.
Note:
1. In the examination each student picks one question from part A.
2. A team of two or three students must develop the mini project. However duringthe
examination, each student must demonstrate the project individually.
3. The team must submit a brief project report (15-20 pages) that must include thefollowing:
a) Introduction
b) Requirement Analysis
c) Software Requirement Specification
d) Analysis and Design
e) Implementation
f) Testing
Course outcomes: The students should be able to:
Design and develop dynamic web pages with good aesthetic sense of designingand latest
technical know-how's.
Have a good understanding of Web Application Terminologies, Internet Toolsother web
services.
Learn how to link and publish web sites
Conduction of Practical Examination:
1. All laboratory experiments from part A are to be included for practicalexamination.
2. Mini project has to be evaluated for 30 Marks.
3. Report should be prepared in a standard format prescribed for project work.
4. Students are allowed to pick one experiment from the lot.
5. Strictly follow the instructions as printed on the cover page of answer script.
6. Marks distribution:
a) Part A: Procedure + Conduction + Viva:10 + 35 +5 =50 Marks
b) Part B: Demonstration + Report + Viva voce = 15+10+05 = 30 Marks. Change of experiment is
allowed only once and marks allotted to the procedure part to be made zero.
