The second option of this program let me find the specific data in the customer_account.dat, but the result found nothing of the record i want even the data is existed when i entered in the first option.In contrary ,if i initialised the name with "Michael" like(string name = "Michael"),it reveal all the information of Michael correctly.Any correction of the codes ,so that i can find the record with cin the name i want ?
