C# provides type-safe object-oriented function pointers in the form of delegates. class Program { // Delegate type: delegate int Operation ( int a , int b ); static int Add ( int i1 , int i2 ) { return i1 + i2 ; } static int Sub ( int i1 , int i2 ) { return i1 - i2 ; } static void Main () { // Instantiate the delegate and assign the method to it.
The function is passed to the operator as a delegate. This implements the Map higher-order function. Where The Where operator allows the definition of a set of predicate rules that are evaluated for each object in the collection, while objects that do not match the rule are filtered away. The predicate is supplied to the operator as a delegate.
Anonymous types are a feature of C# 3.0, Visual Basic .NET 9.0, Oxygene, Scala and Go that allows data types to encapsulate a set of properties into a single object without having to first explicitly define a type. [1] This is an important feature for the SQL-like LINQ feature that is integrated into C# and VB
Microsoft had considered keeping the name "COOL(C-like Object Oriented Language)" as the final name of the language, but chose not to do so for trademark reasons. By the time the .NET project was publicly announced at the July 2000 Professional Developers Conference , the language had been renamed C#, and the class libraries and ASP.NET runtime ...
The standard type hierarchy of Python 3. In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and/or a representation of these values as machine types. [1]
Single precision is termed REAL in Fortran; [1] SINGLE-FLOAT in Common Lisp; [2] float in C, C++, C# and Java; [3] Float in Haskell [4] and Swift; [5] and Single in Object Pascal , Visual Basic, and MATLAB. However, float in Python, Ruby, PHP, and OCaml and single in versions of Octave before 3.2 refer to double-precision numbers.
The C++ standard library provides a complex template class as well as complex-math functions in the <complex> header. The Go programming language has built-in types complex64 (each component is 32-bit float) and complex128 (each component is 64-bit float). Imaginary number literals can be specified by appending an "i".
For every type T, except void and function types, there exist the types "array of N elements of type T". An array is a collection of values, all of the same type, stored contiguously in memory. An array of size N is indexed by integers from 0 up to and including N−1. Here is a brief example:
