"Static" class member

Question

For example, x is static in class's definition. I should use x in this way:

class_name::x; rather than instance_of_class.x;

My question is, is the latter one also legal? Or just not correct?

Thanks.

It is legal and correct, but the general consensus is to use the scope resolution operator.

class_name::x

rather than

instance.x

The only time I've used . was in a template function where it was only sometimes a static member.

Both are valid. The reason to prefer use the first one is to make a reader of your code to understand that the member is static and belongs to the whole class of objects rather than each particular instance.
