ISC Computer practical expected question for this year
{Here are some guess Questions}

*form arrays program to print
=>spiral matrix
=>circularshift the array
=>magic square
=>sort a 2d array

* Strings
=>Program to count number of vowels in a sentence,no of sentences in a string and print other such details

=>program to encode a string using given set of rules.Eg.write a program that will replace every character in a srting with a character which is found next to that character in your keyboard(with few asumptions and other rules..)eg. replace q with w ,t with y ,]with a asume shift is off and caps lock is off....

=>program to replace all character of a string with their ascii value or to create an array of intger that has ascii value of all characters of inputed string in proper order.

=>program to sort words in a string

ObJECT

=>program to find difference in dates.

=>ADD,substract,multiply,find conjugate of complex number after creating proper complex number object

Here is a spicemen paper from ISC
http://www.cisce.org/data/Specimen%20Question%20Paper/3.%20CTS-2-SPECIMEN-2010.pdf

Don't try to solve too many questions and to spend too much time on computer science specially if you are preparing for some competitive exam...

And remember computer practical won't be like chemistry practical where you know ... ... .... Smile

So study properly.Have a good idea of theory and then you can make any program....

r u sure these r the questions

Can you please suggest sample viva questions.....

@roh
WHAT DO YOU MEAN BY

Quote :: r u sure these r the questions

let me make it very very clear that i have NOT Posted ANY LEAKED COMPUTER PRACTICAL paper... please read the post it is just a guess paper.... it is as significant as any model paper that u buy from market and nothing more than that...

@diptojit

viva questions are very simple and are based on your program.

eg.

1)What is significance of import java.io.* in your program
2)difference between if and switch
3)difference between for and while loop
4)difference between do while and while loop
5)types of comments
6)why is S capital in System.out.println
7)what are exceptions
8)types of exceptions
9)define data type
10)what is constant
11)what is meant by static
12)what are objects
13)what is a class
14)why do we have main() function
15)can two functions have same name
16)parts of for loop
17)examiner may ask you to tell what is control variable in your loop
18)difference between variable and constant
19)what are exceptions
20)what is use of throw

Hey just had a question....Can we write the hand-written program for the Computer practical exam in pencil....writing with the pencil is easier as mistakes can be erased without making the work look all messy...I wanted to know if it's ok....

Active member

i think that you may write it with pencil first and then write it with pen later(there is lot of time to do this since practical is of 3 hrs)

can ne1 plz temme hw to solve ds????---

Hey what is the logic for a spiral matrix? Can anyone post the algorithm please?
Thanks!

I feel number to words conversion program will come...here's a program to convert a 4 digit number(at most) in words :-

import java.io.*;
class number_words
{
String unit(int a)// finds unit digit word equivalent
{ String f="";
switch(a)
{ case 1:f="One"; break;
case 2:f="Two"; break;
case 3:f="Three";break;
case 4:f="Four";break;
case 5:f="Five";break;
case 6:f="Six";break;
case 7:f="Seven";break;
case 8:f="Eight";break;
case 9:f="Nine";break;
case 0:f="";break;
}
return(f);
}
String tens(int b)// finds tens digit word eq.
{ String t="";
switch(b)
{ case 2:t="Twenty"; break;
case 3:t="Thirty";break;
case 4:t="Forty";break;
case 5:t="Fifty";break;
case 6:t="Sixty";break;
case 7:t="Seventy";break;
case 8:t="Eighty";break;
case 9:t="Ninety";break;
case 0:t="";break;
}
return(t);
}
String special(int c)// finds special words from 11-19
{ String s="";
switch(c)
{ case 1:s="Eleven";break;
case 2:s="Twelve";break;
case 3:s="Thirteen";break;
case 4:s="Fourteen";break;
case 5:s="Fifteen";break;
case 6:s="Sixteen";break;
case 7:s="Seventeen";break;
case 8:s="Eighteen";break;
case 9:s="Nineteen";break;
}
return(s);
}
String two_dig(String d)// returns two digit number in words
{ int nm,fst,snd;String wrd;
if(d.charAt(1)=='0'&&d.charAt(0)=='1')
{ return("Ten");}// special care if last two digits are 10
if(d.charAt(0)=='1')
{ nm=Character.getNumericValue(d.charAt(1));
wrd=special(nm);// invoke speical if first digit is 1
}
else
{ fst=Character.getNumericValue(d.charAt(0));
snd=Character.getNumericValue(d.charAt(1));
wrd=tens(fst)+" "+unit(snd);
}
return(wrd);
}

void main()throws IOException
{
InputStreamReader read=new InputStreamReader(System.in);
BufferedReader in=new BufferedReader(read);
int n,ln;String str,str1="",word="";String cnt;String hnd;String th;
System.out.println("Enter N");
n=Integer.parseInt(in.readLine());
str=Integer.toString(n);// converting to String
ln=str.length();
String h="Hundred";
if(ln==1)// for one digit number
{ word=unit(n);}
if(ln==2)// for two digit number
{ word=two_dig(str);}
if(ln==3)// for three digit number
{ str1=str1+str.charAt(ln-2)+str.charAt(ln-1);// adding last two digits
cnt=two_dig(str1);// getting word equivalent of last two digits
hnd=unit(Character.getNumericValue(str.charAt(0)));// getting number of hundreds
word=hnd+" "+"Hundred"+" "+cnt;// adding in reverse order
}
if(ln==4)// for four digit number
{ str1=str1+str.charAt(ln-2)+str.charAt(ln-1);// adding last two digits
cnt=two_dig(str1);
if(str.charAt(1)=='0')// not to print "Hundred" if hundred's place is 0
{ h="";}
hnd=unit(Character.getNumericValue(str.charAt(1)));// getting number of hundreds
th=unit(Character.getNumericValue(str.charAt(0)));//getting number of thousands
word=th+" "+"Thousand "+hnd+" "+h+" "+cnt;
}
System.out.println(word);// printing result
}
}

Thanks diptojit. It was very kind of you.

Active member

it's ok yaar....so how was your practical exam ??

Active member

It was really good! I got my output and the program that i had written in the paper had no changes it worked fine! Smile

Only viva was ok ok. Not so great! How was yours?

Active member

Mine was good as well..... program worked well....output also came....and as far as the viva is concerned....don't worry....it's just an eye-wash...everyone is gonna get good marks......cheers !!! java - ISC Computer JAVA practical expected question for this year Icon_biggrin

it's so nice to read all that I had written during those tense exam days....really nostalgic to read these posts again months later.....

plss give algorithm for word conversion by replacing each character with the one next on the keyboard

what is the logic for magic square?

@diptojit ..can u please explain me sorting in java ?????????? i m really weak at it

Hey isc computer practical exam is on 24th ryt?? Question
