Help required on infile problem

[Adrianlcf]

May i know how to write a function readFile that reads customer records from a text file and stores them, in ascending order according to the name, in a linked list. The letters of each name must be converted to the upper case letters. The function reports the number of customer records successfully read as its return value. No duplicate record (according to the account id) should be read in. Need help on this problem.

The customers info are as follows :

Account Id = 123
Name = Matt Damon
Address = 465 Ripley Boulevard, Oscar Mansion, Malaysia 7666322
DOB = 10-10-1970
Phone Number = 790-3233
Account Balance = 405600.00
Account Type = Fixed
Fixed Daily Interest = 0.05
