Below is an address book program I am working on. The way it stands now, when the data is entered and writes to a text file it writes the line of data like,
John Doe 1234 Help Me Avenue Dallas Texas 98956
Johnathan Doe 2345 Derby Lane Omaha Nebraska 45678
What I would like it to do is keep all the data evenly spaced and with headings for each column...
First Name Last Name Address City State Zipcode
John Smith 1234 Help Me Avenue Dallas Texas 98956
Johnathan Doe 2345 Derby Lane Omaha Nebraska 45678
All Help will be greatly appreciated. Thanks!
