HI every one ,Today I attended the online examination for HINDUSTAN AERONAUTICS LIMITED 2012 IN COMPUTER SCIENCE STREAM.I want to share my experience with you regarding the pattern of the questions appeared in the paper.This year mainly the paper contains more no of mathematical questions than the technical questions,some of the technical questions asked in the examination are
1.p is a variable then a)p is a pointer if it holds a value of the other element
b)p is a pointer if it holds another element address as the data of the p c)p is a pointer when it holds only the memory address.
2.main() {
int a,b;
a=-3- -3;
b=-3 -(-3);
printf("%d%d",a,b);
values of a b?
a)6,0 b)0,6
c)0,0
d)6,6
3.complete binary of n vertices contain how many edges
a)n
b)n+1
c)n(n+1)/2
d)n(n-1)/2
4.void display(* first node)
{if(first->next )
printf("%d",first->data);
display(first->next) }
a)displays only the first node
b)displays only next node of the first node
c)displays all the elements of linked nodes d)program not executed;
5.if the inputs of nand gates is to be low then inputs are
6.if there are four inputs to the and gate then to become logic output as high then inputs are 7.
the following is used as a translator
a)compiler
b)lexical analyser
c)preprocessor d)interpreter
8.The following string which do not contain in the grammar (a)* a+ba
a)a
b)aa
c)aaba
d)aababa
9.the following grammar is a{a,b,c:aNbMcK where n,m,k are powers and >1}
a)regular
b)cfl but not regular
c)csl
d)type 0 grammar
10. main(){
for(i=-1;i<10;i++)
if(i<5)
continue;
else
break;
printf("india bix"); }
a)prints 0 times
b)prints ten times
c)prints 11 times
d)prints infinity number of times
11.x.e power(2x+5Y)then dy/dx partial differentiation wrt to x
a)2xe power(2x+5Y)
b)e power(2x+5Y)
c)xe power(2x+5Y)
d)(2x+5)
12.f(x->y) is one-one and g(y->z)is one-one then fg(y->z)is
a)it is one -one if f is one-one
b)it is onto if f is onto
c)it is not one-one if f is not one-one
d)it is not onto if f is not onto 13.f(x)=x2-2x+1 g(x)=(x-1)(x+3)then f(x)/g(x)=
{a)x-1)/x+3
14.find tens complement of the (751)base 8
etc are some kind of technical questions .today major part of questions are asked from the mathematics nearly 50 % mathematics out of 100 questions in technical and that to are asked from discrete mathematics i.e functions and limits etc.and some of the aptitude part also includes like PERMUTATIONS AND COMBINATIONS .No one will expect this kind of paper where there is less technical part so we will hope better for the results.
apart from these to get successful in hal examinations you have to be thorough with the following concepts
1)basics of toc and acd
2)trees
3)paging and memory in os
4)programming in c,c++ concepts pointers,linked list
5)data structures like stack, queue.
but from todays paper we can infer that we must also concentrate on mathematics and aptitude GENERAL AWARNESS
GENERAL AWARNESS QUESTIONS ARE EASY .20 QUESTIONS
ENGLISH LANGUAGE HAS SOME PASSAGES
AND MEANINGS AND OPPOSITE WORDS CONCLUSION REFERENCES
REASONING PART IS VERY EASY AND CONTAINS BASICS LIKE RELATIONS ,DIRECTIONS, SERIES ETC OVERALL PAPER IS AVERAGE BUT NOT ACCORDING TO THE EXPECTATIONS IN TECHNICAL POINT OF VIEW.yours friendly blogger
