Paper – 2
Class 12, Half Yearly Examination
(Planning Session and Examination Session : Three hours)
Maximum Marks: 30
(Candidates are allowed additional 15 minutes for only reading the paper. They must NOT start
writing during this time)
----------------------------------------------------------------------------------------------------------------------------
The total time to be spent on the Planning session and Examination session is Three hours.
Planning session: 90 minutes
Examination session: 90 minutes
Note: Candidates are to be permitted to proceed to the Examination Session only after the
90 minutes of the Planning Session are over.
----------------------------------------------------------------------------------------------------------------------------
This paper consists of three problems from which candidates are
required to attempt any one problem.
Candidates are expected to do the following:
1. Write an algorithm for the selected problem.
(Algorithm should be expressed clearly using any standard scheme such as pseudo code or
in steps which are simple enough to be obviously computable) [3]
2. Write a program in JAVA language. The program should follow the algorithm and should
be logically and syntactically correct. [5]
3. Document the program using mnemonic names / comments, identifying and clearly
describing the choice of data types and meaning of variables. [2]
4. Code / Type the program on the computer and get a print out ( Hard Copy ). Typically, this
should be a program that compiles and runs correctly. [2]
5. Test run the program on the computer using the given sample data and get a print out of the
output in the format specified in the problem. [3]
In addition to the above, the practical file of the candidate containing the practical work related
to programming assignments done during the year is to be evaluated as follows:
Programming assignments done throughout the year [15]
