Simple C++ Bank Management System Project

Overview of Bank Management System

This C++ Bank Management System project is a simple console-based application developed without graphical components. It is more of a C++ database project and is built using the language’s file-handling mechanism. It is suitable for beginners who want to learn how to add, edit, find, delete, or modify records in a file, and how to use the file as a database in general.

This system relies on insights into customer record information. Here customer can do all formalities like adding new account details and depositing the account, customer can withdraw the amount, customer can check the balance, viewing details of all record holders, closing records, etc. Similarly, there is no login framework for this project system.

This Project coding has been presented in a very understandable way. The source code needs to be compiled in Code::Blocks IDE using GCC compiler. there are other similar projects of C++ you can check it out below.

Summary of Bank Management System Project:

File handling has been effectively used for each and every feature of this project. Here, I’ll briefly describe these features.

  • Add Record: For this function, the void read_data() function has been used to add bank records to the file. Request information such as account number, name, surname, and balance to be entered.
  • Show/List Data: Using the information provided in Add Record, the void show_data() function in this C++ Bank Records System project displays records related to a particular account number, first name, and last name. The current balance of the account holder is displayed.
  • Search Log: When the function is run for the first time for this function, it displays the total records in the file and the user can search by record number. If the record you are looking for is not found, the C++ Bank Records System Project displays the message: “Error opening! File not found!!”
  • Edit Record: It works just like the search function. When the Edit Record function is run for the first time, it displays the total records in the file and the user can edit the information by providing the record number. The C++ project then displays all the data in that record and the user can enter any data to modify. If the record to be edited is not found, it displays the message: “Error opening! File not found!!”
  • Delete record: Firstly, when the task of this feature is executed, it displays all the records in the file and the user can enter the record number to delete. If the record is not found, this C++ Bank Records System Project displays the message: “Failed to open! File not found!!”
