Handphone untuk saat ini bukanlah lagi untuk begaya, namun sudah menjadi kebutuhan khususnya bagi masyarakat Indonesia. Saya akan membahas tentang sebuah handphone yang berinisial SE berseri W830i apakah termasuk produk gagal atau tidak. Dari berbagai keluhan yang terdengar handphone tersebut mempunyai rincian kelemahan sebagai berikut:
1. bling putih pada layar/white secreen
2. ketika dinyalakan LCDberkedip
3. Untuk penerimaan signal nya kurang bagus
4. handphone slide cenderung lebih rentan akan bantingan.
5. agak lemot
 Untuk kelebihannya adalah:
1. untuk music cukup bagus karna seri ini lebih ditekankan untuk entertainment musicnya.

Dari perbandingan tersebut tentunya anda bisa menilai apakah itu termasuk produk gagal untuk dijaman yang sangat menuntut mobilitas yang tinggi ini.

object oriented programming using cpp

( Common with Information Technology)
3 - 6
Object orientation is a new approach to understand the complexities of the real world. In contrast
to the earlier approaches like procedural etc, object orientation helps to formulate the problems in a
better way giving high reliability, adaptability and extensibility to the applications. The students are
already familiar with this concept of programming in C which is the basic for C++. This course
offers the modern programming language C++ that shall help the students to implement the
various concept of object orientation practically. The students will be able to programme in the
object oriented technology with the usage of C++.
1. Introduction and Features (5 hrs)

inheritance, polymorphism, dynamic binding, message passing
2. Language Constructs (13 hrs)
Review of constructs of C used in C++ : variables, types and type declarations, user
defined data types; increment and decrement operators, relational and logical operators; if
then else clause; conditional expressions, input and output statement, loops, switch case,
arrays, structure, unions, functions, pointers; preprocessor directives
3. Classes and Objects (6 Hrs)

and destructors, constructor for virtual base classes, constructors and destructors of
derived classes, and virtual functions, size of a derived class, order of invocation, types of

streams, stream classes, header files, updating of file, opening and closing a file, file
pointers and their manipulations, functions manipulation of file pointers, detecting end-offile.
1. Write a function using variables as arguments to swap the values of a pair of integers
2. An election is contested by five candidates. The candidates are numberd 1 to 5 & voting is
done by marking the candidate number on the ballot paper. Write a program to read the
ballot & count the votes cast for each candidate using an array, variable count. In case, a
number read is out side the range 1 to 5, the ballot should be considered as a ' spoilt
ballot' and the program should also count the number of spoilt ballot.
3. Write a program to read a matrix of size m*n from the keyboard and display the same on
the screen.
4. Write a macro that obtain the largest of three number.
5. As the practical 4, using inline function. Test the function using the main program.
6. Define a class to represent a bank account including the following members:- Data
a) Name of the depositors
b) Account number
c) Type of account
4. Balance amount in the account
Member function
- To assign initial values
- To deposit an amount
- To withdraw an amount after checking the balance
- To display the name and balance.
7. Modify the class and the program of practical 6 for handling 10 customers.
8. Create 2 classes OM and DB which store the value of distance. DM store distances in
meters and cm and DB in feet and inches. Write a program that can read values for the
class objects and add 1 object OM with another object of DB. .
Use a friend function to carry out the addition operation the object that stores the results
may be a DM object or a DB object, depending upon the units in which the results are
require. The display should be in the format of feet and inches or meters and cms
depending on the object on display.
9. A book shop maintains the inventory of books that are being sold at the shop the list
includes details such as author, title and publisher and stock position. Whenever a
customer wants the book, the sales person inputs the title and author and the system
search the list and display whether it is available ornot. If it is not, a appropriate message
is displayed, if it is, then the system displays the book details and requests for the number
of copies require. If the requested are available, the total cost of the required copies is
displayed: otherwise the message" Required copies not in stock"is displayed. Design a
system using a class called books with suitable member functions and constructors. Use
new operator in constructor to allocate memory space require.
10. Define a class string that could work as a userdefined string type include constructors that
will enable us to create an .un-initialized string
String s1; :/ string with length 0
And also to initialize an object with string constant at the time of creation like
String s2("well done"); .
Include a function that adds two strings to make a third string.
11. Create a class float that contains 2 float data member. Over load all the 4 arithmetic
operators so that do operate on the objects of float.
12. Create a class MAT of size m*o. Define all possible matrix operation for MAT type objects
13. Define 2 classes POLAR and RECTANGLE to represent points in the POLAR and
RECTANGLE systems. Use conversion routines to convert from one system to the other.
14. Create a base class called shape use this class to store two double type values that could
be used to compute the area of fig. Derive the specific class called TRIANGLE and
RECTANGLE from the data shape. Add to base class, a member function get - data ( ) to
initialize base class data members and another member and another member function
display – area( ) to compute and display the area of the fig.. Make display – area ( ) as a
virtual function and redefine function in the derived classes to suit their requirements,
Using these 3 classes design a program that will accept dimension of RECTANGLE or
TRIANGLE interactivity and display the area.
Remember the 2 values given as input will be treated as length of 2 sides in the case of
rectangle and as base and height in the case of triangles and used as follows:
Area of rectangle = x*y
Area of triangle = 1/2 *x*y
