When overriding one method with another, the signatures of the two methods must be identical (and with same visibility). In C#, class methods, indexers, properties and events can all be overridden. Non-virtual or static methods cannot be overridden. The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method. This is done using the same signature of a property or method but adding the modifier new in front of it.
1 This is what I remember of static functions in C. This may be different in C++.  static variables are initialized the moment the executable starts, and keep their state no matter what scope encloses them, whether in module scope, or inside of functions, or inside of classes.
