An archetypal example is the TryParse method in .NET, especially C#, which parses a string into an integer, returning true on success and false on failure. This has the following signature: [ 17 ] public static bool TryParse ( string s , out int result )
In Visual Basic 6, event handler subs must have a specific name consisting of the object's name (Command1), an underscore (_), and the event's name (Click, hence Command1_Click). There is a function called MessageBox.Show in the Microsoft.VisualBasic namespace which can be used (instead of MsgBox ) similarly to the corresponding function in ...
YAML (/ ˈ j æ m əl /, rhymes with camel [4]) was first proposed by Clark Evans in 2001, [15] who designed it together with Ingy döt Net [16] and Oren Ben-Kiki. [16]Originally YAML was said to mean Yet Another Markup Language, [17] because it was released in an era that saw a proliferation of markup languages for presentation and connectivity (HTML, XML, SGML, etc.).
Python uses the + operator for string concatenation. Python uses the * operator for duplicating a string a specified number of times. The @ infix operator is intended to be used by libraries such as NumPy for matrix multiplication. [104] [105] The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to ...
Values of the union type can correspond to either union case. The types of the values carried by each union case is included in the definition of each case. The list type is an immutable linked list represented either using a head:: tail notation (:: is the cons operator) or a shorthand as [item1; item2; item3]. An empty list is written [].
For instance, the n th complex root of a number should yield n distinct complex numbers, but if another m th root is then taken of those results, the final m•n values should be identical to the output of the m•n th root. List completely automates this issue away, condensing the results from each step into a flat, mathematically correct list ...

The Sun Microsystems Java compiler requires that a source file name must match the only public class inside it, while C# allows multiple public classes in the same file, and puts no restrictions on the file name. C# 2.0 and later allows splitting a class definition into several files by using the partial keyword in the source code. In Java, a ...
