2- Modify the case study, so that client data contains branchID as Integer that holds the branch id of the client.
3- Modify the case study again, add another functionality called “Backup Data” which copies the client data file to another file called backup.dat.
4- Modify the case study again, add another functionality called “Restore Data” which copies the client data from the backup file to credit.dat.
5- The program should check for existing files, if the credit.dat doesn’t exist, it should create it and insert 100 blank records. If backup.dat doesn’t exist, it should display an error on restore.
