This document summarizes a student project on a banking management system developed in C++. The project allows users to open and close accounts, deposit and withdraw funds, check balances, and list account details. The main functions include writing account data to a binary file, reading specific records, modifying or deleting records, and depositing or withdrawing amounts. The output screens showcase account creation, transactions, inquiries and reports. Future enhancements proposed are adding new bank policies, enabling online transactions, and improving the user interface.

 Abstract
The main objectives of this banking system which
is developed in C++ is to provide a flexible solution
for banking industry. With this system, both of
users such customer and working personnel of the
particular bank will find easy to use and able to
perform all their operations using the system. This
system enable its users to open and close the bank
account. Customers will able to withdraw and
deposit amount to their particular account.
Working personnel of particular bank will make all
the operations which are required within the
banking premises. The operation which can be
performed by bank personnel are: Adding new
customers account, modifying existing account, list
all customer details including their account
number. And also in the perspective of customers it
helps in easy of accessing and reduces time. Its user
friendly graphical mode will make its users to work
with this new system in more interactive way.

 Description
This project makes use of some of the concepts of the OOPS and data
file handling mechanism. These are as follow:-
1. Header files-The header files in C++ library helps to
access data type function prototype, definitions for library
functions. The header files included in this program are:
include<iostream.h>
include<conio.h>
include<cctype.h>
include<iomaniph.n>
include<stdlib.h>
2. Classes- It is a collection object, where objects having its
own attributes and functions. The class Created is:-
class account
3. Functions – These are individual piece of code or modules
which can be used anywhere in the program by calling
them when needed. The functions can be predefined or
user defined. Some of the user defined function created in
the program are:-
void create_account()
void show_account()
void modify()
void dep()
void draw()
void report()
int retacno()
int retdeposit()

6. 4
char retype()
void write_account()
void display_sp()
void modify_account()
void delete_account()
void display_all()
void deposit_withdraw()
void intro()
4. Switch Case: It is the multiple branch selection
statement. The selection statement successively tests the
value of an expression against a list of integer or
character constant.
5. IF and ELSE statement: ‘IF’ statement test a particular
statement if the condition evaluates to true i.e., a set of
statements are executed if the condition is true. If the
condition is not true i.e., is false then the set of statement
in ‘else’ condition is executed. Both the ‘if’ and ‘else’
statement are never executed simultaneously.
6. Fstream: The fstream library predefines a set of operation
for handling file related to input and output.
infile
outfile
system(‘cls’)
ostream

Future Enhancement
In any project, though present satisfaction is important
but also it is equally important to see and visualize the
future scope. The project which is developed now may
be need to undergo some changes in future in order to
match up the technology prevailing that time, thus
change due to development in technology are advisable.
Some of the future scope are:-
1. One can extend this project with any of the new
policies launched by the banks.
2. The transactions are in off-line mode, hence can
make this project to support on-line transactions
depending upon the efficiency and effectiveness.
3. This project can be made more user friendly than
now.
