Hi,
I know there exists a good reason why the designers of c++ decided that
function hiding should exist. But I don't know why. Can anybody provide
a good reason/example of a case where function hiding saves the day. I
know there exists one, I'd just like to hear about it.
thanks and have a nice day.

Hi all,
I have been wondering for a while why function hiding (in a derived
class) exists in C++, e.g. why when writing
class Base {
void foo( int ) {}
};
class Derived: public Base {
void foo( char const ) {}
};

Users are validated by checking to see if they exist...

Hi,
first, python is one of my fav languages, and i'll definitely keep
developing with it. But, there's 1 one thing what I -really- miss:
data hiding. I know member vars are private when you prefix them with
2 underscores, but I hate prefixing my vars, I'd rather add a keyword
before it.
Python advertises himself as a full OOP language,...

I'm trying to become familiar with the information hiding design rules, and I
