SAMPLE VIVA VOICE QUESTIONS IN CQ1. What are different data
types in C?
Ans. Integer (int), character (char), floating point (float)
Q2. What is a variable?
Ans A variable is a data name that may be assigned to store a
data value.
Q3. What is compiler?
Ans. A compiler is a computer program (or set of programs) that
transforms source code written in a computer language (the source
language) into another computer language (the target language,
often having a binary form known as object code). The most common
reason for wanting to transform source code is to create an
executable program.
Q4. What are different types of C operators?
Ans. Arithmetic op, Relational op, logical op, assignment op,
increment /decrement op
Conditional op
Q5. What is a conditional operator?
Ans. The ?: operator is just like an if .. else statement except
that because it is an operator you can use it within
expressions.
Syntax:
e1 ? e2 : e3Q6. Differentiate between keywords and
identifiers
Ans. Keywords are reserved words like(static,public......) which
has a special meaning for compilers.
Identifier can be name of any variable or any name used to
identify an object or entity .hence keywords cannot be used as an
identifier
Q7. What is the use of modulus(%) operator?
Ans. It returns remainder of a division.
Q8.Differentiate between pre-increment/decrement(++a/--a) &
post-increment/decrement(a++/a--)
Ans. They both increment the variable. But the value returned by
the pre-increment operator is the value of the variable after it
has been incremented, while the value returned by the
post-increment operator is the value before it has been
incremented.
Q9. How do you classify the control statements?
Ans. C provides two sytles of flow control:
Branching(if,if-else,switch-case,goto)
Looping(while, do-while, for statement)
Branching is deciding what actions to take and looping is
deciding how many times to take a certain action.
Q10. Differentiate between while and do-while loop.
Ans. In case of while loop first the control checks the
condition given inside while ,and it executes only if the condition
is true,And in case of do-while the control first executes the one
time and then checks the conditions if it is true control go
further else comes out.
Q11. What is looping?
Ans. During looping a set of statements are executed until some
conditions for termination of the loop is encountered. A program
loop therefore consists of two segments one known as body of the
loop and other is the control statement. The control statement
tests certain conditions and then directs the repeated execution of
the statements contained in the body of the loop.
In looping process in general would include the following four
steps 1. Setting and initialization of a counter 2. Exertion of the
statements in the loop 3. Test for a specified conditions for the
execution of the loop 4. Incrementing the counter
Q12. What is an array?
Ans. Array by definition is a variable that hold multiple
elements which has the same data type.Ex: int marks[10], char
name[25]
Q13. Name the different string handling functions
Ans. strcat() - This function is used to con concatenate two
strings. strcmp() This function is used to compare two strings.
strcpy() This function h is used to copy the second string given as
second parameter to this function into first string. strlen() This
function is used to length of the string in other words the number
of characters present in string . strstr() This function is to
obtain the first occurrence of substring in a string .
Q14. Which header file contains string handling functions?
Ans. String.h
Q15. Name the different methods of parameter passing?
Ans. Pass by value: Values of actual parameters are copied to
the variables in the parameter list of the called function. The
original data in the calling function cannot be changed
accidentally.
Pass by address(pass by pointer): The memory address of the
variables rather than the copies of the values are sent to the
called function. In this case, the called function directly works
on the data in the calling function and the changed values are
available in calling function.
Q16. What is scope of the variable?
Ans. The scope of variable determines over what region of the
program a variable is actually available for use.
Q17. What are the storage classes in C?
Ans. 1. automatic variables 2. external variable 3. static
variables 4. register variables
Q18. What are global variables?
Ans. Global variables have to be defined globally, persists
(life is) throughout the program, scope is also throughout the
program. This means such variables can be accessed from any
function, any file of the program.
Q19. What is a structure?
Ans. In some programming contexts, you need to access multiple
data types under a single name for easy manipulation; for example
you want to refer to address with multiple data like house number,
street, zip code, country C supports structure which allows you to
wrap one or more variables with different data types. A structure
can contain any valid data types like int, char, float even arrays
and other structures.
Q20. What are structure members?
Each variable in structure is called a structure member.
Q22. How can you define a structure?
Ans. Defining structure
To define a structure, you can use struct keyword. Here is the
common syntax of structure definition:
struct struct_name{ structure_member };
Q23. Differentiate between array and structure.
Ans. Arrays are collections of repeated data items. Structures
are complex data items made up of other data items, including,
potentially, other structures and arrays.
Q24. How do you access the member of a structure?
Ans. The structure members can be accessed with the help of
structure variables. The link between the structure members and
structure variables can be established by using a member
operator(.) or dot operator.
Q25. What is union?
Ans. A union, is a collection of variables of different types,
just like a structure. However, with unions, you can only store
information in one field at any one time.
You can picture a union as like a chunk of memory that is used
to store variables of different types. Once a new value is assigned
to a field, the existing data is wiped over with the new data.
Q26. W hat is recursive function?
Every function in C may be called from any other or itself. Each
invocation of a function causes a new allocation of the variables
declared inside it. Such functions are called recursive
functions.
Q27. What is a pointer variable?
Ans. A pointer variable is a variable that may contain the
address of another variable or any valid address in the memory.
Q28. What is the need for an escape sequences?
Ans. \n New line
\tHorizontal Tab
\vVertical Tab
\bBackspace
\rCarriage Return
\fForm feed
\aAudible Alert (bell)
\\Backslash
\?Question mark
\'Single quote
\"Double quote
Q29. What is unary operator?
Ans. Increment(++) and decrement(--) operators are known as
unary operator.
Q30. What are logical operator?
Ans. The commonly used logical operators are:
Logical AND (&&)
This operator is used to evaluate 2 conditions or expressions
with relational operators simultaneously. If both the expressions
to the left and to the right of the logicaloperator is true then
the whole compound expression is true.
Logical OR (||)
The logical OR is used to combine 2 expressions or the condition
evaluates to true if any one of the 2 expressions is true.
Logical NOT (!)
The logical not operator takes single expression and evaluates
to true if the expression is false and evaluates to false if the
expression is true. In other words it just reverses the value of
the expression.
Q31. What are logical errors in c?
Ans. A logic error produces unintended or undesired output or
other behavior, although it may not immediately be recognized as
such even though the program may not give any error messages.
Q32. What are semantic and syntax errors?
Ans. Semantic errors: In programming, writing a valid
programming structure with invalid logic. The compiler will
generate instructions that the computer will execute, because it
understands the syntax of the programming statements, but the
output will not be correct.
Syntactic error: An error in the format of a statement in a
computer program that violates the rules of the programming
language employed. Also known as syntactic error.SAMPLE VIVA VOICE

PROCEDURES- VBSCRIPT PROVIDES WITH TWO TYPES OF PROCEDURES SUB AND
FUNCTIONS. IT IS A SERIES OF VBSCRIPT STATEMENTS.VARIABLES-TO
ALLOCATE MEMORY AND STORE VALUES AND HOLD RESULTS.RULES-THEY MUST
BEGIN WITH ALPHABETICAL CHARACTERS; THERE MUST NOT BE MORE THE 255
CHARS AND ONLY UNIQUE NAMES. 24. FUNCTIONS-25. DIFFERENCE B/W
INLINE AND EXTERNAL STYLESHEETS. INLINE ARE DESIGNED BY USING THE
STYLE ATTRIBUTE TO INSERT A STYLE RULE DIRECTLY INTO A HTML TAG. IT
IS CONCEPT BY CREATING A SINGLE.CSS FILE WHICH CAN LINKED TO
MULTIPLE HTML DOCUMENTS.26. EMBEDDED STYLE SHEET- IT IS PLACED
DIRECTLY WITHIN THE HEAD PORTION OF AN HTML FILE. THE STYLE SHEET
IS APLLIED ONLY TO THE SPECIFIC HTML FILE WHERE THEY ARE PLACED.25.
EXTENSIONS- XML- .XML, HTML-.HTML, STYLESHEET- .CSS.27. DTDS DATA
TYPE DEFINITION EXTRENAL DTD- IN THIS THE DTD FILE IS CREATED
EXTRENALLY INTERNAL DTD- IN THIS DTD IS CREATED IN THE SAME FILE
WHERE XML FILE IS CREATED.28. IMPORTING STYLESHEET INTO XML - 29.
FILTERSthe filter property allows you to add more style effects to
your text and image. types- fliph, flipv, glow, shadow, dropshadow,
wave.30. TRANSITIONS IT IS ONE OF THE MOST USEFUL FEATURE OF DHTML,
USING IT CAN IMPLEMENT FAST & EASY VISUAL EFFECTS ON THE WEB
PAGES WITH SIMPLE HTML AND LESS SCRIPT CODE.30.ATTRIBUTES OF IMAGE

BASIC TECHNOQUES USED FOR DATA VALIDATION IN CHECKING TEXT ENYTERED
INTO THE TEXT BOX.TYPES32. INPUT BOX IT IS FUNCTION MAKES IT
POSSIBLE TO GET INPUT FROM A USER WITHOUT PALCING A TEXT CONTROL ON
THE FORM. N= INPUTBOX ("ENTER THE VALUE OF N", "RANGE") MESSAGE
BOX- IT IS USEFUL WHEN WE WANT TO NOTIFY A USER THAT AN EVENT HAS
OCCURRED. If(m=s) then MsgBox "the reverse of the " &m& "
is : " &s& " is palindrome" else MsgBox "the reverse of the
" &m& "is :" &s& "is not a palindrome"33. VARIOUS

VALUE.SAMPLE VIVA VOICE QUESTIONS IN JAVA1. Features of Object
oriented programming:-Object, Class, Encapsulation, Inheritance,
Polymorphism, Abstraction, Message Communication2. Object: - Object
is a run time entity which is an instance of class. 3. Class: -
Class is a model or blue print or Imagination to represent the
object. Class also consists of some properties and some
behaviors.4. NoteClass doesn't exist physically. Object exists
physicallyWithout Class Object does not exist. But without object
Class can exist. 5.Encapsulation:- Binding or wrapping of data
members inside single unit (class) is called as
Encapsulation.6.Inheritance: - It is a mechanism of acquiring the
properties of one class into another class without redefining that
class.7. Polymorphism:- Poly ->many morphism->formsIt is an
ability to take more than one form. 8.Abstraction:- Hiding the
necessary data from other classes is called Abstraction. 9.Message
Communication: - Transferring the data from one class object to
another class object is called as Message communication.10. Access
specifier:-Access specifier is a keyword that controls the
visibility of class members.There are 4 types of access specifiers:
- private, public, protected, default11.Private: private members of
class are not available to any other class. The scope of private
members is within a class only.12.Public: public members of class
are available anywhere outside the class.13.Protected:-protected
members of class are available in same package but not in another
package i.e. protected members have package scope14.Default: -
default members of class are available in same package but not in
another package i.e. default members have package
scope15.Difference between protected and defaultProtected member of
class are available for the subclass even though the subclasses are
available in another package16.Packages:-Packages are
subdirectories to hold the classes and interfaces.Packages can be
extended and we can create our own packages also1. Built-in
packages:-These packages are provided in javaExamples java.io.*;
java.lang.*;java.awt.*;* stands for all classes and interfaces2.
User defined package: - These packages are created by userPackage
is a keyword to create the package17.Casting: - Converting one data
type into another data type Is called casting18.Primitive data
types (holds single value):- byte, char, short, int, long, float,
double19.Command Line arguments: - The parameters passed to the
main method before execution of program through command line are
called as command line arguments.20.Constructor: -Constructor is
similar to method which is used to initialize the class data
members. Constructor name is same as class name. Constructor does
not have any return type even void also.21.Constructors are of two
types: - Default constructor: - The constructor without parameter
is called default constructor Parameterized Constructor:-The
constructor with parameters is called parameterized
constructor22.Advantages1. Constructor executes faster than
functions.2. Constructor name can be remembered easily.23.Naming
Conventions in java1. Packages should be defined in small
letterjava.lang, java.io, java.util, java.applet, java.sql,
java.awt2. Each word of class or interface should start with
capital letterjava.lang.System, java.io.InputStreamReader,
java.io.BufferedReader, java.util.Date,
java.awt.event.ActionListener3. The method name should start with
small letters and then each word should start with capital
lettersprintln(),readLine(),getNumberInstance(),forName()4. The
variable names should also follow above rules.5. Constant should be
defined in capital letters: - final double PI=3.145;24.InterfaceAn
Interface is a specification of method prototype.All the methods of
interface are abstract and public by default.We cannot create
object to interface but we can create a reference
variable.25.Abstract methodThe method without body is called as
abstract method.Abstract method must be declared as abstract by
using abstract keyword.26.Abstract classA class with 0 or more
abstract methods is called as abstract class. An abstract class can
have general methods and abstract methods also.27.MethodMethod is a
group of statements to perform a particular task.28.Compile time
polymorphism:- polymorphism exhibited at compile time is called as
'Static Polymorphism' .In static polymorphism method call is linked
with method body at compile time. 29.Method overloading:- If two or
more methods are written with samename but with difference in
parameters is called as method overloading.30. JVM can identify the
methods seprately by the difference in 1. in number of arguments2.
in the data types of parameters3. in the sequence of
arguments31.Method signature: - Any one of the above difference is
called as method signature. Method signature uniquely identifies a
method by difference in parameters.32.Dynamic polymorphism:-
polymorphism exhibited at run time is called as 'Dynamic
Polymorphism. In dynamic polymorphism method call is not linked
with method body at compile time. JVM will identify the correct
method depending upon super class reference referred with either
super class object or sub class object & executes it at run
time. This means method call is linked with method body at run
time. This is called as dynamic polymorphism or dynamic binding or
late binding 33.Method overridingWriting two methods with same name
and same method signature in super class and subclassis called
method overriding. Generally sub class method will override super
class method.34.Static methodStatic method is a method which can be
called without creating an object to the class.Static is a keyword
to define static method.35.Super It is a keyword to access1. Super
class instance variables2. Super class parameterized constructors3.
Super class methodsNote:- Calling the super class parameterized
constructor must be first statement in subclass constructor.Super
class default constructor is automatically available to subclass
but superclass paramterised constructor is not available to sub
class36.this It is a reference .It refers to current class object
i.e. this can be used to1. To refer present class parameterized
constructor2. To refer present class instance variables3. To refer
present class methods37.Wrapper classesWrapper classes wraps or
contains primitive data types in their objects.Wrapper classes are
used to convert primitive data types into objects.38.ArrayListIt is
dynamically growing array which stores the objects.39.StackStack is
a data structure which follows LIFO (LAST IN FIRST OUT) i.e. the
element which is inserted last will be removed first.40.Queue is a
data structure which follows FIFO (FIRST IN FIRST OUT) i.e. The
element which is inserted first will be removed first.The insertion
of the element takes place at one end which is called as rear end
and deletion of the element takes place at another end which is
called as front end.41.VectorIt is also dynamically growing array
which stores the objects. But it is synchronized.42.AppletsAn
applet is a java code that is embedded [inserted] in a HTML
page.Applet=HTML+java code43.ExceptionAn Exception is runtime
error.44.What are checked and unchecked exceptions?The exceptions
which are caught by java compiler are called as checked exception
The exceptions which are caught by JVM are called as unchecked
exception 45.What is the difference between error and Exception?An
exception is an error which is handled by programmer46.Types of
Exceptions1. Builtin ExceptionsThese exceptions are part of
java1.ArithmeticException2.ArrayIndexOutOfBoundsException3.StringIndexOutOfBoundsException4.FileNotFoundException5.NoSuchMethodException6.NullPointerException7.InterruptedException8.IOException9.RuntimeException2.
Userdefined ExceptionThese Exceptions are created by user1.Write a
class that extends Exception class2. Write default constructor in
the class3. Write a parameterized constructor with string as a
parameter4. Create an object to your class and throw it out using
throw clause when required47.What is Thread Synchronization?When a
thread is processing an object, keeping other threads waiting till
the first thread comes out of the object is called Thread
synchronization.48.ThreadThread represents a process or execution
of the statement.JVM uses internally threads to run a javaProgram
.Every java program will have a thread.49.To set the priority of
threadt.setPriority(int priority);The priority no. costants are
given belowThread.MAX_PRIORITY value is 10Thread.MIN_PRIORITY value
is 1Thread.NORM_PRIORITY value is 550.Where the threads are
useful?1. Threads are used in animation & creating the games.2.
Threads are used in server to handle 100000's of clients&
creating the games.51.Creating a threadExtend Thread class or
implement Runnable interface. Example class MyThread extends
Thread{...........}class MyThread implements
Runnable{...........}PAGE
