Write the programs for the following problems in C.
1. Swap two variables x,y without using a temporary variable.
2. Write algorithm for finding the GCD of a number.
3.Write a program for reversing the given string.
4. The integers from 1 to n are stored in an array in a random
fashion. but one integer is missing. Write a program to find the
missing integer.
Ans). Hint : The sum of n natural numbers is = n(n+1)/2.
if we subtract the above sum from the sum of all the
numbers in the array , the result is nothing but the
missing number.

ans; none of those
2.Truth table of a logic function
ans: displays all its input output possibilities
3.The process of varying one signal according to the pattern
provided by another signal is
ans:modulation
6. Data Structures
. What is data structure?
A data structure is a way of organizing data that considers not only the items
stored, but also their relationship to each other. Advance knowledge about the
relationship between data items allows designing of efficient algorithms for the
manipulation of data.
2. List out the areas in which data structures are applied extensively?
Ø Compiler Design,
Ø Operating System,
Ø Database Management System,
Ø Statistical analysis package,
Ø Numerical Analysis,
Ø Graphics,
Ø Artificial Intelligence,
Ø Simulation
3. What are the major data structures used in the following areas : RDBMS, Network
data model & Hierarchical data model.
Ø RDBMS – Array (i.e. Array of structures)
Ø Network data model – Graph
Ø Hierarchical data model – Trees
4. If you are using C language to implement the heterogeneous linked list, what pointer
type will you use?
The heterogeneous linked list contains different data types in its nodes and we
need a link, pointer to connect them. It isnot possible to use ordinary pointers for this. So
we go for void pointer. Void pointer is capable of storing pointer to any type as it is a
generic pointer type.
5. Minimum number of queues needed to implement the priority queue?
Two. One queue is used for actual storing of data and another for storing
priorities.
6. Future Soft
1. S --> AB|AS
A --> a|aA
B --> b
What is the grammer accepted by the above?
Ans. aa*b
2. How many address lines are needed to address a 64Kb segment with each register storing upto
512 bytes.
Ans. 14 address lines

14. Hughes 1999 Paper 5
There were two papers one was aptitude ( 36 questions) and other was
technical(20 questions)
1: given an expression tree and asked us to write the in fix of that expression
four choices
2:
global variables in different files are
a:at compiletime
b) loading time
c) linking time
d)execution time
15. Hughes Test
1:a machine A wants to set it's time same as a a machine B
so it sends a packet to B and b sends reply.but the time on packet is over
by the ti mete packet reached
A. Ahas to
a:set the time on packet
b:increment its time slowly so as to reduce difference
c:send packets repeatedly till it gets a packet with time less tan the
current time
d:....
## I think the solution could be something like this:
Send 'n' ('n' should be large) packets to Machine B and calculate the avg time it takes
to reach Machine B from Machine A. Now at the last packet, add this avg time to the
time stamp of Machine B and use this to set the time at Machine A.
