== Static Table Generation ==

The benefit of static tables is the replacement of "expensive" calculations with a simple array indexing operation (for examples, see [[lookup table]]). In C++, there exists more than one way to generate a static table at compile time. The following listing shows an example of creating a very simple table by using recursive structs and [[Variadic templates]].

The table has a size of ten. and eachEach value is just the indexsquare multipliedof withthe itselfindex.
