Writing data list to output file

[EthanT24]

Hey guys, I am working on a program right now that will read customer info over to an invoice for an output file. The data I am reading is:

George Washington
703-780-2000
100 50 3
Black

Dan Goldberg
800-600-6014
2 2 1
Red

How can I read these specific lines of string directly to an output file?
Thanks!
