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. [6] In the above example, hiding causes the following:

For instance, in C#, the base method or property can only be overridden in a subclass if it is marked with the virtual, abstract, or override modifier, while in programming languages such as Java, different methods can be called to override other methods. [15] An alternative to overriding is hiding the inherited code.
Due to the C++ language not having a dedicated keyword to declare interfaces, the following C++ example uses inheritance from a pure abstract base class. For most purposes, this is functionally equivalent to the interfaces provided in other languages, such as Java [4]: 87 and C#. [5]: 144
In other textbooks, [1] the term socket refers to a local socket address, i.e. a "combination of an IP address and a port number". In the original definition of socket given in RFC 147, [ 2 ] as it was related to the ARPA network in 1971, "the socket is specified as a 32-bit number with even sockets identifying receiving sockets and odd sockets ...

A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.
For example, a default constructor for a restaurant bill object written in C++ might set the tip to 15%: Bill () : tip ( 0.15 ), // percentage total ( 0.0 ) { } The drawback to this is that it takes two steps to change the value of the created Bill object.
