Here's an example: I'm reading the Strings stored in the EEPROM, each String can vary in size and obviously I won't know the size of each String. So if I have to read each String from each address I can't specify the length of the character array I'm using to store each character of the String since I will have to read more than one String from the EEPROM and each one will vary in size. If I use Strings instead of character strings then I don't need to specify the size. I want to this advantage. I hope you understand my example. Thanks
