Writing to a non-.txt file

[xander333]

Hello there,

I'm on vacation in the Maldives and in the meantime i'm writing an addressbook in C++. I use .txt files atm to save the data, bu I don't think that's very safe, security wise :)
So, is there an alternative filetype to write to, without having to use external libraries (so just STD)?
If not, which ones are good?

thanks!

It does not depend on the file type, it depends on how (encrypted) you save the data.

What's the problem with external libs?

Take a look at these simple solutions. Though the more complex the better, or just use a database instead like MySQL.
