PREFACE

For effective and sound management, anorganization

Require a software program that exclusively fulfills its everincreasing indispensable needs thereby rendering success onsumptuous target in time.

In order to accomplish the above stated success acompetent technology is required. So, I present a software inC++ on BANKING MANAGEMENT SYSTEM. Thoughevolving such a software in C++ entails a lot of diligence yet

accomplishment of a fully operable and user friendly softwareis not feasible.

The project manages the daily transactions of bankviz. opening/closing accounts, deposits, withdrawals,generating account statements, account info, calculation ofinterests and many more .

The project has been designed with meticulouspreparation and astute analysis of the subject with the soleaim to meet and satisfy the needs .To err is human. Keenefforts have been made to avoid the shortcomings.Though the suggestions/criticism in this regard will begratefully acknowledged.

INTRODUCTION

The task of managing the daily transactions at a bankviz. opening/closing accounts, deposits, withdrawals,generating account statements, account info, calculation ofinterests , etc. entails sheer amount of endeavor andmaintenance. The need is of an efficient application thatunravels the problems. The project on THE BANKING

SYSTEMhere presented unravels most of the aboveproblems.

The complete project has been developed in C++ which

perhaps is a good programming language having an object-

oriented approach. The concept offile handling and classes

has been deployed to render extensive functionality to the

project. The application includes a login portal to the systemfrom where a user can login to the main application page

perform all the above listed functions/transactions by opting

the required choice in a very easy and lucid manner. Though

the application is based on the conventional file system,

efforts have been applied to fulfill all the requirements and

make the project user friendly. In spite of this, the projectoffers functionality near to the widely used database system.

We have tried to incorporate nearly all the functions

that are required in banks and assure that it will meet theneeds extensively.

OVERVIEW OF C++

C++ is an object oriented programming language.It was developed byBjarne stroustrup at AT&T Bell Laboratoriesin New Jersey, USA in the early 1980s. Stroustrup combined bestfeatures of the languagessimula67and Cand created a languagethat could support object-oriented programming features retaining

the power and elegance of C. The result was C++. Simula67 addedthe feature of object oriented programming. The new language wasalso known as C with classes.

Being the superset of C, C++ provides the additionalobject-oriented features which includes objects, classes, dataabstraction and encapsulation, inheritance, polymorphism, dynamicbinding, message passing, function overloading and operator

overloading . These features enable creation of abstract data types,inherit properties from existing data types and polymorphism,thereby making C++ a truly object-oriented language.

Objects are basic runtime entities in an object-oriented system. They are chosen such that they match closelywith the real world objects. Objects take up space in the memoryand have an associated address. When a program is executed, the

objects interact by sending messages to one another.

Classes are the most remarkable feature of C++. The

class binds together data and which work on data. The class is anabstract datatype so creation of class simply creates a template. Inclass we define data members and member functions. There arethree different types of modes:public, private and protected. Datamembers and functions declared under the public mode can be usedinside and outside the class. Private data members and functionscan only be used inside the class. Protected data members andfunctions can be used inside the class and any class immediately

derived from it.

Inheritance is the process by which objects of oneclass acquire the properties of objects of another class. In OOP,inheritance provides the idea of reusability. This means that we canadd additional features to an existing class without modifying it.They are of five types viz. single, multiple, multilevel, hybrid andhierarchial.

File handlingis the mechanism used to access datafiles using C++ codes. We can read or write any data to a data file.In this project we are using data files like newrecords.dat, calcu-lations.txt& transactions.dat respectively used to store recordsof account holders, store the calculations related to the accounts,store the transactions processed to the accounts.

The object-oriented features in C++ allow program-mers to build large programs with clarity, extensibility, and easeof maintenance.

CONCLUSION

The project presented on the banking managementsystem rendered us valuable erudition.Working on the project

made us aware of the daily transactions and works in the banks.It rendered us knowledge in depth. It also made us aware ofthe varied usage of C++ in the field of software development.

File handling in C++ proved to be a magicwand in creation of the application. It not only minimized thetime of creation and the complexity of the code but alsohelped us to render proper shape to the application. Moreover

it also provided us with the knowledge of its usage in the fieldof application development.

57/58

The application performed well than was

expected. The operations of account opening, viewingaccount info, generating interests and closing of accountwere accomplished successfully.

The successful completion of project has providedus the proper opine and now we look forward to getinvolve in more projects like this.
