Company: HCL Technologies

Dear Murthy! Yaa! you are luck fellow. I got HCL full paper. I am mailing it.
The quetions are in order. So you no need to prepare answers and mugging that
that quetions. Just you mug that answers which are in order or you write all
these answers on the hand compactly while you are going to exam.
Paper Model:
Section I: computer awareness(i.e general things about computer) Q.15
-ve marks: 1/4
Section II: Simple C- language Q. 15 & -ve marks: -1/4
Section III: On pointers & structures
and C++,JAVA( only 1 on this) Q.10 each quetion ->2 marks
-ve marks: -1
Section IV: Analytical Q.20 each quetion -> 2 marks.
-ve marks: -1/4
Murthy from each section I am giving one are to quetions also because for
checking whether the same paper or not.
And for doubtful answers also I am writing quetions but not writing answers
for these quetions.
