Hi!,

Well, let's imagine that I have a program which gets the age and name from console. The program will ask for the data until user presses 'q'. Data has to be within computer memory, until 'q' is pressed. And when it is pressed, then the program would write the information to the file.

Now I have to problems with this:

1) How to hold different types of variables in memory (vector's just for specific type?!)

2) How to encrypt the content of the file, yet if i would start the decrypter, it would show me the data as same way as user had entered.

Thanks,
