/*The following C++ code is for, Bank Management Applications. This includes, Account Creation, Deposit, Withdraw, Modify A/C Details, Balance Check, etc. The C++ code is in "Bold" & The comments and other explanations are not in bold text. We have not tried to make the code more intricate, just kept it simple. The following C++ Code For Banking Management Project, includes File system access, so all the data gets stored in external '.dat' binary file, that will be created during run time. The following C++ code was tested in MS Visual Studio 2010, if your need to run in Turbo C++ just include ".h" in the header file section.*/
