sets of question papers. .
section : computer science general knowledge
2. Computer science general: simple questions
acquired this company in 2002. Which is the company

2. What does
a) 3rd generation mobile communication b) 3rd generation computer

backend of some application like databases:
a) application server b)proxy server c)database server

b) It can be accessed by a client program using imap protocol
c) option 3
d) option 4
Ans: I don't remember the answer but first 2 are true.
quesion regarding the company and who developed it ( the thing to remember
is that Apple produce Macintosh computers).
section: questions on c/c++, programs o/p etc.
1 main( )
unsigned int i=3;
while( i >=0)
printf( "%d", i--);
how many times will the printf stmt be executed?
a)0 b)3 c)4 d)infinite
Ans: I think the answer is infinite, b'cos 'i' is an unsigned integer
and it will not
decrement below '0' and hence end up in an infinite loop.(yes, i
checked and it
is getting stuck in an infinite loop)
2. main( )
int x,y, z;
printf("%d %d %d", x, y z);
a)3 5 7 b)option 2 c)option 3 d)option 4
3 # define
swap(a,b) temp=a; a=b; b=temp;
int i, j, temp;
if( i > j)
swap( i, j );
printf( "%d %d %d", i, j, temp);
Ans: On compiling i got ans 10, 0, 0. I did not understand the concept.
expalin this to me.
section: questions on java related stuff.
1) Java was initially code named as:
a)Oak b)green c)miller d)option4
5. What is

a) it is compiled using javac compiler
b) the compiled files have .class extension.
c) such files cannot be transfered from one comp to another.
d) they use the java interpreter
6. Why is the
a) to initialize multiple objects b)to lock an object c)option3 d)option
Ans: b (probably)
