INSPIRATIONAL QUOTES
Many of lifes failures are people who did not realize how close they were to success when they gave up

1> The starting location of an array is 1000. If the
array[1..5/...4] is stored
in row major order, what is the location of element
[4][3]. Each work occupies
4 bytes.
2> If the number of leaves in a binary tree are N,
then the total number of
internal nodes........(Assume complete binary tree)
ANS: N-1
3> The locality of reference means........
4> If two ausigned 8 bit numbers are multiplied what
is the memory space required......
5> The vector address of RST 7.5 is .........
ANS: 003C (multiply 7.5 by 8 and convert to hex)
6> int b = 0xAA;
b>>4;
printf("%x",b);
What is the output of the above program....
7> struct s1 { struct { struct {int x;}s2}s3}y;
How to access x?
ANS: y.s3.s2.x
8> Why there is no recursion in Fortran?
ANS: There is no dynamic location (Check this)
9> What is the worst case complexity of Quick sort?
ANS: O(n^2)
10> Quick sort uses....
Ans: Divide and conquer
11> In a sequential search, the time it takes to search through n elements is
12> What is the size of the array declared as double *X[5]
ANS: 5* sizeof (double *)
13> A binary search tree is given and asked to write the preorder traversal result.
14> If size of the physical memory is 2^32-1, then the size of virtual memory......
15> S-> A0B
A-> BB0
B-> AA1 How many strings of length 5 are possible with the above productions??
16> (3*4096+15*256+3*16+3). How many 1's are there in the binary representation of the result.
ANS: 10
17> In memory mapped I/O how I/O is accessed.....
ANS: Just like a memory location (Means, I/O devices can be accessed using the instructions like mov A,M etc...)
18> What is the use of ALE in 8085.......
ANS: To latch the lower byte of the address.
19> If the logical memory of 8 X 1024 is mapped into 32 frames, then the number of bits for the logical address ......
ANS: 13
20> Context free grammar is useful for...
ANS: If-then structures.
21> In ternary number representation, numbers are represented as 0,1,-1. Here -1 is represented as - (1 bar). Then how is 352/9 represented......
1
22> There are processors which take 4,1,8,1 machine cycles respectively. If these are executed in round robin fashion with a time quantum of 4, what is the time it take for process 4 to complete....
ANS: 9
