PROJECT OVERVIEW

This bank management system is a replica of the software used in banks to manage customer accounts. The software can be accessed only when a valid password in entered. It contains functions for storing and displaying customer details and managing his account effectively. It also displays the various transactions of the account holders. It also provides an overview of the banks past record and future plans.

The bank management system employs a wide range of header files, functions, and classes. The purpose of each one of them has been specified below: -

(i) HEADER FILES : -

(a) iostream.h: - It contains various input and output functions.(b) conio.h: - It contains the function clrscr() which is used for clearing the

screen.(c) string.h: - It contains the function strcmp() which compares the alphabets of

two words.(d) stdio.h: - It contains the function printf() which sends the formatted text to the

output screen.(e) dos.h: - It contains the function delay() which delays the output displayed on

the screen for a specific period of time.(f) process.h: - It contains the function exit() which terminates the program.(g) fstream.h: - It contains the stream classes ifstream which is used to read from

a file and ofstream which is used to write to a file.(h) iomaniph,h: - It contains the function setw() which prints the next output after

a specified space.

(ii) FUNCTIONS: -

(a) void about_us: - Displays the historic background of the bank.(b) bank_acc::bank_acc: - Constructor of class bank account for initializing

the user’s balance to zero.(c) void trans::disp(): - function of class trans to display transaction headings.(d) int match(long intacno, char pw [10]):- Compares the password and

account number entered by the user.(e) clrscr(): -Clears the screen.(f) void trans::show_trans: -Function of class trans to display transactions of

various account holders.(g) void bank_acc::ba getdata(): -Function of class bank account to get user’s

details.(h) void bank_acc::ba_showdata(): - Function of class bank account to display

user’s details.(i) void bank_acc::ba_deposit(): - Function of class bank account for

depositing money by the user.(j) void bank_acc::ba_withdraw(): - Function of class bank account for

withdrawing money by the user.

(k) void bank_acc::ba_showall(): - Function of class bank account for withdrawing money by the user.

(l) int match_pass(char pw[10]): - Function for matching the password of the user with the already existing password.

(m) int match(long int acno,char pw[10]): - Function to comparethe account number and password entered by the user.

(n) void main_screen(): - Function for bthe main screen.(o) void set_screen(): - Function to display how to enter his or her choice.(p) void menu1(): - Function for the main menu which shows various options

for the user.(q) bk.ba_getdata(): - Function to get user details.(r) void close_acc() : - Function for closing an existing account.(s) void menu2(): - Function for displaying the menu after the user has logged

on.(t) void login(): - Function to take in user’s account number and password

and login in order to withdraw, deposit, close and carry out other operations.

(iii) CLASSES: -

(a) class bank_acc: - Class to hold the details of a user opening an account in the bank.

(b) class trans: - Class to hold the details of the user’s transactions.
