STL sets and MultiSets

[nadz]

Ok, I need a good online tutorial for STL sets and Multisets. Because the
following line of code should work right

multiset<myClass> foo;
myClass fubu;
foo.insert(fubu);

or am I doing something wrong.

Thanks a lot.

Have you got a "bool operator<(const myClass& rhs) const"
for myClass?

Or, depending on the nature of myClass, a friend function:

bool operator<(const myClass& lhs, const myClass& rhs);
