A function that calls itself is said to be recursive. Recursive logic can often be implemented as a loop, too. Recursion must be controlled with a parameter, so that the function knows when to stop recursing and deepening the call stack. Infinite recursion eventually causes a run-time error '28': &q...

Operators are used to assign or compare values. They consist of a single symbol or keyword and are usually sandwiched between a left and a right value. For example: right = left. Operators are intrinsic to the language (such as =), and not functions such as those provided by System.Math.

The assignment of string-literals in VBA is confined by the limitations of the IDE and the codepage of the current user's language settings. The examples above demonstrate the special-cases of escaped strings, special, non-printable strings and long string-literals. When assigning string-literals...

The term literal is commonly used to describe a sequence of characters in a C code that designates a constant value such as a number (e.g. 0) or a string (e.g. "C"). Strictly speaking, the standard uses the term constant for integer constants, floating constants, enumeration constants ...

Variables are used for storing values. Let the value be of any type , we need to store it somewhere so that we can use it throughout the console/script. Variable names in PowerShell begin with a $, as in $Variable1, and values are assigned using =, like $Variable1 = "Value 1".PowerShell su...

Type conversion is converting one type of data to another type. It is also known as Type Casting. In C#, type casting has two forms: Implicit type conversion - These conversions are performed by C# in a type-safe manner. For example, are conversions from smaller to larger integral types and conve...
