In the beginning I was nervous as well as anxious to complete the

project and see the final output of the project. In this journey of project

development many people supported me in many ways to complete this

project.

I owe my earnest thanks to our worthy Principal Sir, Shri S.T.METRE

who permits me to work on this project and use the computer lab for

development purpose.

I bestow my heartfelt thanks to our Computer Science PGT, Shri

Deepak Gosain Singh Gosain, who helped and guided us at every step and

without his guidance and help this project would not be completed.

I also thank to my classmates who helped me while developing this

project and helped to debug it.

he primary aim of this project is to fulfill the partial requirement for

the AISSCE 2016 practical examination of Computer Science. TAfter learning C++ in class XI and XII, it is a great experience to

develop software in C++. It is really a joy to make project in C++ . My

project title is “Monthly Pay Automation System” that have following

features :

Create a database to store employee record and monthly

salary.

Add new employee record in the employee file.

Modify existing employee record the employee file.

Delete existing employee record.

Generate the monthly pay slip for each employee.

Generate all report of all employees

Generate department wise report of the employees.

Search the employee record on the basis of employee code.

The purpose behind this is to consolidate the concepts and practices

imparted during the course and to serve as a record of competence in

object oriented programming and to implement its key features.

P a g e | 5

This project includes all major key concepts that we have learned

through Computer Science course i.e. Binary File Handling, Classes and

Objects, Inheritance, and structure, function and reusability.

HARDWARE & SOFTWARE REQUIREMENT

(A) MINIMUM HARDWARE REQUIREMENT-

An Intel based central processing unit capable of running any sort of windows operating

system such as Pentium based workstation.

• Minimum 64 MB RAM (128 MB Desirable) at server.

• Minimum 60 MB of free disk space for files.

• A CD ROM drive

• Minimum 128 MB of RAM at workstation.

• VGA 15” color monitor for workstation.

(B) MINIMUM SOFTWARE REQUIREMENT-

The software requirements are as follows.

• Windows XP/ 7/ 8 or Above

• Turbo C++ 4.5 Editor is used for developing this project It is compiled at 32

bit windows mode.

• Microsoft Word 2010 is used for documentation purpose on Windows 8 OS

INTRODUCTION OF C++ AND FEATURES OF OOP

he C++ programming language was developed at AT&T Bell

Laboratories in the early 1980s by Bjarne Stroustrup. He found ‘c’

lacking for simulations and decided to extend the language by adding

features from his favourite language, Simula 67 was one of earliest

object-oriented language. Bjarne Stroustrup called it “C with Classes”

originally. The

Tname of C++ (pronounced C plus plus ) was coined by Rick Mascitti where “++” is the C

increment operator .Ever since its birth ,C++ evolved to cope with problems

encountered by users , and through discussions at AT&T . However, the maturation of

the C++ language was attested to by two events:

I. The formation of an ANSI ( American National Standard Institute) C++ committee.

II. The publication of The Annotated C++ Reference Manual by Ellis.

The major reason behind the success and popularity of C++ is that it supports

the object oriented technology, the latest in the software development and the most

near to the real world .

One can easily judge the judge the importance of C++ as given in the following

lines:

“Object Oriented Technology is regarded as the ultimate paradigm for the

modeling of information, be that data or logic. The C++ has by now shown to

fulfill this goal”.

OBJECT ORIENTED PROGRAMMNING:

OOP stands for Object Oriented Programming. In, Object-Oriented Programming

(OOP), the program is organized around the data being operated upon rather than the

operations performed. The basic idea behind OOP is to combine both, data and its

P a g e | 7

functions that operate on the data into a single unit called object. Following are the

basic OOP concepts:

1. Data Abstraction 2. Data Encapsulation 3. Modularity

4. Inheritance 5. Polymorphism

OOP provides the following advantages :

OOPs is closer to real world model.

Hierarchical relationship among objects can be well-represented through

inheritance.

Data can be made hidden or public as per the need. Only the necessary data is

exposed enhancing the data security.

Increased modularity adds ease to program development.

Private data is accessible only through designed interface in a way suited to the

program.

Following are the general OOP concepts: 1. Data Abstraction: Data abstraction means, providing only essential information to

the outside word and hiding their background details i.e. to represent the needed

information in program without presenting the details.

2. Data Encapsulation: The wrapping up of data and operations/functions (that

operate o the data) into a single unit (called class) is known as Encapsulation.

3. Modularity: Modularity is the property of a system that has been decomposed into a

set of cohesive and loosely coupled modules.

4. Inheritance: Inheritance is the capability of one class of things to inherit capabilities

or properties from another class.

5. Polymorphism: Polymorphism is the ability for a message or data to be processed in

more than one form.

DATA STRUCTURE USED IN PROJECT

Data Structure is a named group of data of different data types which can be

processed as a single unit. A data structure has well defined operations, behaviours and

properties.

P a g e | 8

In this project we have used following data structures:-

Primitive Data Types:- All fundamental data types such as char, int, float, double,

float and void are implemented in this project.

Non-Primitive Data Types :- Those data types which are composed of primitive data

types are called user-defined or non-primitive data type. In

this project uses array, structure, and class non-primitive

data type.

Pointer: A special data type pointer data type has been introduced by some

programming languages. The pointer data type enables

storage of pointers i.e. addresses of some other data location.

Pointer has great use in linked list, stack and queue.

Binary Files: One binary file database.dat is used in this project to store the data of the

employees, and their salary details.

Inheritance: Single inheritance between base class employee and sub class salary is

implemented in this project.

The application certainly has some striking feature over manual system. Some of

the main feature of this project is as follows:-

User queries have become quite accurate and efficient.

Lot of paper work has been eliminated.

Future modification and enhancements have become quite easier now in

comparison to the previous manual system.

The whole procedure will take too less time in comparison of the manual

system.

No doubt this project will be helpful for institutes in all procedure, which will be

monitoring through Account. At the first step this system will only be installed in the

any office with small number of employees.

The main advantage of this system is that, it will become a powerful tool in

establishment of better system in comparison of the existing system. It helps to protect

the system from the corruption. After installation of this system in institutions, there is

a greater possibility of stabilization a clear and fair system, which will be accurate,

update and fast.

P a g e | 27

There is no doubt that there always remains some scope of improvement. The

important thing is that the system developed should be flexible to accommodate any

future enhancements. This system can be used to provide some enhancement without

rewriting of existing code.
