Help Converting to read from data file

[Godwin5174]

//This the one that requires a binary search of the data. Your program should read the //charge account numbers from a file and the contents of the file should be unsorted. The //charge accounts are found the problem entitled Charge Account Validation.

//The file will have one charge account number on each line of the file. You will need to //create your own data file. The file should be named: chargeaccounts.dat
