Note:
Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Q.1
Write short notes on:
a)
Switch statement
Answer: A switch statement allows a
variable to be tested for equality against a list of values. Each value is
called a case, and the variable being switched on is checked for each case.
The
syntax for a switch statement in C++ is as follows:
switch(expression){
case constant-expression :
statement(s);
b)
Conditional Operator
Answer: The conditional operator (? :) is
a ternary operator (it takes three operands). The conditional operator works as
follows:
·
The first operand is implicitly
converted to bool. It is evaluated and all side effects are completed before
continuing.
·
If the first operand evaluates
to true (1), the second operand is evaluated.
·
If the first operand evaluates
·
·
Q.2
Differentiate between Classes and Objects. Write an example program to
represent a class and its object.
Answer: Objects and classes are used in
object oriented programming languages. All object oriented programming
languages such as C++, Java, .NET and others, employs objects and classes.
Objects:
An object is defined as any entity that
can be utilized by using commands in a programming language. Object can be a
variable, value, data structure or a function. In object oriented environment,
object is referred to as instance of a class. Objects and classes are closely
related to each other. In real world, the objects are your TV, bicycle, desk
and other entities.
Q.3
Differentiate between Containers and Iterators.
Answer:Container classes are building blocks used to create objectoriented
programs, and they make the internals of a program much easier
to construct.
·
A container class describes an object that holds other objects.
·
Container classes are so important that they were considered fundamental to early objectorie ted languages.
·
The C++ approach to containers is based on templates. The containers in the Standard C++ library represent a broad range of data structures
Q.4
Describe the two basic exception handling models.
Answer: Exceptions in process modeling indicate
a problem that occurs and changes the normal flow of the process. When an
exception occurs in the process, the process execution stops at that point.
There are two types of exceptions in the process composer: an error and an
escalation. They are differentiated by their trigger.
To
model exceptions and exceptions handling you create the following event types:
·
Error end event, which you
create in the process.
·
The error end event triggers a
WSDL fault that is defined in a service interface definition you have in your
project.
Q.5
Write a C++ program to swap two numbers without using a temporary variable.
Answer: Program which swaps the values of
two variable without using extra variable. The program calls another function
which takes variables as the arguments by reference and manipulates them in
order to swap their values inside the function body.
Here is source code of the C++ program
which swaps the values of two variable without using extra variable.
The
C++ program is successfully compiled and run on a Linux system. The program
output is also shown below.
Q.6
Write A C++ program to implement class rectangle and find its area.
Answer: #include<iostream.h>
#include<conio.h>
class circle
{
private:
int radius;
