using a custom class in a list

[cppaddict]

What do I have to do in order to create a list of one of my own classes?
That is, in order for:

list<myClass> myList;

to be a valid statement. I know I might have to define an iterator on it,
or implement operators like ++, but I don't know the details. Can anyone
let me know, or point to a good reference on the web?

Thanks,
cppaddict

You need to

a) Include the <list> header
b) Declare std::list so that it could be named 'list' (no std::)
c) Make sure your 'myClass' is
1) Assignable
2) Copy-constructible

Only the name 'myClass' defined :

# include <list>

class myClass
{
};

int main()
{
std::list<myClass> myList;
}

And that's it (try it).

God, no!! That's why there is a library already written for you.

Iterators do not depend on the contained object, but on the container.
Operators concerning that iterator are defined by that iterator, no by you.

Concerning the standard library, get "The C++ Standard Library" by Josuttis.
