Confused

ohsimplyme (17)
I've hit a roadblock and I'm not sure how to proceed, I'm writing a code that reads in a file of names and adresses and writes it out to a comma separated file, but I'm not sure how to proceed from here:
Needs to be reformatted to - Lastname, Firstname, Social Number, Phone Number, Address, City, State, Zipcode. Thanks for your help!

You can't insert anything with an negative index.
To swap firstname and lastname it's better to use n.find(' ') or a stringstream.
