This document contains the source code for a C++ bank management system project. It includes class definitions and functions for creating, modifying, deleting, and viewing customer bank accounts that are stored in a binary file. The main function provides a menu for performing operations like depositing, withdrawing, viewing balances and account details, and listing all accounts. Header files are included for input/output streams, character handling and file manipulation.
