A property of a class is not shared by all the objects/instances of that class. It's true that all instances have that property, but the value of the property may be different for each instance.

A static property in a C++ class is a property that is available to all instances of the class AND it has the same value for all instances. Ie: If the property is modified in one instances, than its new value is available to all instances.

>Yes, a property of a class is shared with other instances, but in most cases this is OK. It's been my experience that statics are used mainly as counters, so, in the class set the property to 0 then use it in each instance. The fact that each instance gets this property should not cause a problem.
