I'm struggling trying to complete the rest of my C++ program

Code: http://pastebin.com/m3e26ab95

The program lets the user be the customer, banker, or supervisor, and all of their privileges involve structs. I made an array of 100 structs for 100 potential customers, and I need to do something similar for banking.

I'm trying to put customer and banker's info detailed in that struct into a list on a text file that opens at the program startup, reads from it, writes to it, etc...otherwise users need to remake their account EVERY time they use the program

I need help finishing that part, and any additional stuff would be fan-TAST-ic...

You could start by breaking up the thing using smaller functions rather than using one long function. I just don't want to read all that stuff in main (maybe someone else might).

It might help if you used the standard string type and stanard collections rather than using char arrays for strings and fixed arrays for collections.

Kind of like this? I'm unsure about reading/writing to files though, everything to do with file I/O, the struct

struct customerInfo{ char firstName[20]; char lastName[20]; float amount; AccountType type;};

is how I want object in the file to be stored as, e.g.

"Carol Burns
$423.04
Checking

Brandon Jay
$0.01
Credit" etc...

The trouble is reading from/writing to these abnoxious files
