Let's say I have:
class myClass
std::list<myClass> myList
where myClass does not define the == operator and only consists of public fields.
In both VS2010 and VS2005 the following does not compile:
myClass myClassVal = myList.front();
std::find( myList.begin(), myList.end(), myClassVal )
complaining about lack of == operator.
I naively assumed it would do a value comparison of the myClass object's public members, but I am almost positive this is not correct.
I assume if I define a == operator or perhaps use a functor instead, it will solve the problem.
Alternatively, if my list was holding pointers instead of values, the comparison would work.
Is this right or should I be doing something else?
