    hold on what're you saying (baffled), that the characters are like member variables of the string object?
    With the implementation that I have in mind, the characters belong to a dynamically allocated array. There is a pointer member in the String object that points to the first character of this dynamically allocated array.

    When you access s[0], it accesses[0], returning it by reference. Therefore, the address of s[0] is the address of[0]. Hence, if &s is equal to &s[0], then &s is equal to &[0].

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    the "[]" is like overloaded operators which behaves like a function..
    ah yeah, I get you.
    Thanks for clarifying that!
    You ended that sentence with a preposition...Bastard!
