MySQL provides an enumerated type ENUM with allowable values specified as strings when a table is created. The values are stored as numeric indices with the empty string stored as 0, the first string value stored as 1, the second string value stored as 2, etc. Values can be stored and retrieved as numeric indexes or string values. [10] Example:
void Increment (ref int x, int dx = 1) {x += dx;} int x = 0; Increment (ref x); // dx takes the default value of 1 Increment (ref x, 2); // dx takes the value 2 In addition, to complement optional parameters, it is possible to explicitly specify parameter names in method calls, allowing to selectively pass any given subset of optional ...
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
even = x (2:: 2); odd = x (:: 2); is how one would use Fortran to create arrays from the even and odd entries of an array. Another common use of vectorized indices is a filtering operation.
The designers chose to address this problem with a four-step solution: 1) Introducing a compiler switch that indicates if Java 1.4 or later should be used, 2) Only marking assert as a keyword when compiling as Java 1.4 and later, 3) Defaulting to 1.3 to avoid rendering prior (non 1.4 aware code) invalid and 4) Issue warnings, if the keyword is ...
Folds can be regarded as consistently replacing the structural components of a data structure with functions and values. Lists, for example, are built up in many functional languages from two primitives: any list is either an empty list, commonly called nil ([]), or is constructed by prefixing an element in front of another list, creating what is called a cons node ( Cons(X1,Cons(X2,Cons ...
When an enumeration is used in an ordered list context, we impose some sort of ordering structure requirement on the index set.While we can make the requirements on the ordering quite lax in order to allow for great generality, the most natural and common prerequisite is that the index set be well-ordered.
Add two values, returning a new value. Base instruction 0xD6 add.ovf: Add signed integer values with overflow check. Base instruction 0xD7 add.ovf.un: Add unsigned integer values with overflow check. Base instruction 0x5F and: Bitwise AND of two integral values, returns an integral value. Base instruction 0xFE 0x00 arglist
