b) 0.1011
c) 0.1111
d) none
2.( 1a00 * 10b )/ 1010 = 100 (b)
a) a=0, b=0
b) a=0, b=1
c)
d)none
3. in 32 bit memory machine 24 bits for mantissa and 8 bits for exponent. to increase the range of floating point.
a) more than 32 bit is to be there.
b) increase 1 bit for mantissa and decrease 1 bit for exponent
c) increase 1 bit for exponent and decrease one bit for mantissa
5. in C “X ? Y : Z ” is equal to
a) if (X==0) Y ;else Z
b) if (X!=0) Y ;else Z
c) if (X==0) Y ; Z

if (a&b) return 1;
return 0;
a) if either a or b are zero returns always 0
b) if both a & b are non zero returns always 1
c) if both a and b are negative…….
7. typedef struct nt{——–} node-type

8. function gives some error what changes as to be made
void ( int a,int b){
int t; t=a; a=b; b=t;
a)define void as int and write return tt
b)change everywhere a to *a and b to *b
9. which of the following is incorrect
a) if a and b are defined as int arrays then (a==b) can never be true
b) parameters are passed to functions only by values

10. include
void swap(int*,int*);
main()
int arr[8]={36,8,97,0,161,164,3,9}
for (int i=0; i<7; i++) for (int j=i+1; j<8;j++) if(arr void swap(int*x,int*y) int temp; static int cnt=0; temp= *x; *x=*y; *y=temp; cnt++; cnt = ?

PART 2: HERE A PROBLEM IS DEFINED YOU HAVE TO WRITE A PROGRAM IN C OR C++ TWO SCHOOLS,HAVING DIFFERENT NO. OF CLASSES . EACH CLASS HAS DIFFERENT NO. OF SECTIONS.THE 2 SCHOOLS HAVE TO BE MERGED TOGETHER SO THAT A STUDENT OF SAME CLASS AND SECTION REMAIN SAME. FOR EXAMPLE, 1A STUDENTS OF BOTH SCHOOLS SHOULD BE IN 1A SECTION OF NEW SCHOOL WRITE A PROGRAM FOR THE ABOVE USING.
1) DYNAMIC MEMORY ALLOCATION
2) SRUCTURES
3) in iitk about 400 students attended for written test and only 18 students were shortlisted. After interview they have selected only 8 students ( 1 from mtech and 7 from b.tech) MBT one to one negative marking is there.it is tough to qualify unless u know the paper.totally there are 105 questions. 70 min. three flow sheets—- 10 min. sections are quantitative(23),analytical(about 20) ,series&venn diagrams,logical(20) questions from a passage (about 10). time span for each section is different.sit at the back so that u can turn pages if u want.different colored papers are used. for flow sheets first one is relatively easy 1.u will be given conditions like if a wins he gets 100 pts,if b wins he gets 50 pts etc 2.there is flow sheet& there are empty cells(4) at “yes’ or ‘no” decision points. 3.for each cell 4 choices will be given which should be chosen by following through initial conditions &flow sheet logic. 4.rem. -ve marking is there. no verbal questions. rs aggarwals verbal& nonverbal book verbal— pg. 254 pr. 53 to56(almost same) 246 eg.2 pg 104 exer.3a about 5to 6 series qu.are there.so do well pg.354-355 8,13, 6th doubt 4 conclusions r there in all question. pg.115—-qu.36 nonverbal—-pg.5 41,54,108,145,158 241 is doubtful Ans. to one quant. is 200/3% anals 1.six persons will be there. Killer,victim,hangman,judge,police,vitness a,b, c,d,e,f u have to match conditions like,a is the last person to the victim alive,will be given as clues.so we can conclude that a is the killer. This is an easy one .paragraph will be very big .don’ worry 5 to 6 ques. 2. 5 persons will be there. cashier, A clerk,buyer,manager,floorwalker(check in info. paper for exact question.) a,b,c,d,e will be their names. conditions will be given&we have to match who is who 3 r women&2 r men in this sample condition, cashier&clerk if get married, b will be wise man mrs.c husband has some business prob with manager manager&cashier(or clerk) r classmates etc. will be given do quantitative qu. from back. Data graphs on turnover,gross profit &net profit will be given& u have extract data from that &find out few ratios.(easy one) Mahendra- British telecom I) Distribution of workers in a factory according to the no.of children they have Figure 1. Total no. of workers in the factory. Ans : 200 2. Total no. of children that all the workers that have between them is=20
