The Local Void is a vast, empty region of space, lying adjacent to the Local Group. [ 3 ] [ 4 ] Discovered by Brent Tully and Rick Fisher in 1987, [ 5 ] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments ". [ 4 ]
The Hercules Supercluster separates the Northern Local Void from the Boötes Void. [2] The Perseus–Pisces Supercluster and Pegasus Supercluster form a sheet separating the Northern Local Void and Southern Local Void from the Pegasus Void. [2] Southern Local Supervoid: 96 Mpc 112 Mpc Giant Void: 13 h 01 m +38.7° z=0.116 300-400 Mpc
The void pointer, or void*, is supported in ANSI C and C++ as a generic pointer type. A pointer to void can store the address of any object (not function), [ a ] and, in C, is implicitly converted to any other object pointer type on assignment, but it must be explicitly cast if dereferenced.
The KBC Void (or Local Hole) is an immense, comparatively empty region of space, named after astronomers Ryan Keenan, Amy Barger, and Lennox Cowie, who studied it in 2013. [1] The existence of a local underdensity has been the subject of many pieces of literature and research articles.
In computer programming, a virtual method table (VMT), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding).
It was also permitted by many of the derivative programming languages including C, C++ and Java. The C# language breaks this tradition, allowing variable shadowing between an inner and an outer class, and between a method and its containing class, but not between an if-block and its containing method, or between case statements in a switch block.

Local variables are destroyed when the local block or function that they are declared in is closed. C++ destructors for local variables are called at the end of the object lifetime, allowing a discipline for automatic resource management termed RAII, which is widely used in C++. Member variables are created when the parent object is created.
