A function is basically a named block of code. When you call the function name, the script block within that function runs. It is a list of PowerShell statements that has a name that you assign. When you run a function, you type the function name.It is a method of saving time when tackling repetitiv...

This extension filters data by either validating or sanitizing it. This is especially useful when the data source contains unknown (or foreign) data, like user supplied input. For example, this data may come from an HTML form. mixed filter_var ( mixed $variable [, int $filter = FILTER_DEFAULT ...

virtual void f(); virtual void g() = 0; // C++11 or later: virtual void h() override; void i() override; virtual void j() final; void k() final; Only non-static, non-template member functions can be virtual. If you are using C++11 or later, it is recommended to use ...

R has many built-in functions to work with probability distributions, with official docs starting at ?Distributions. There are generally four prefixes: d-The density function for the given distribution p-The cumulative distribution function q-Get the quantile associated with the given probabi...

(define (name arguments ...) body) (function arguments ...)

-- defining a function with no arguments looks the same as simply defining a value language = "Elm" -- calling a function with no arguments by stating its name language -- parameters are separated by spaces and follow the function's name add x y = x + y -- call a function in the s...

The main difference between macros and functions is, that macros are evaluated within the current context, while functions open a new scope within the current one. Thus, variables defined within functions are not known after the function has been evaluated. On the contrary, variables within macros...

Anonymous functions can be created using LAMBDA. Local functions can be defined using LABELS or FLET. Their parameters are defined the same was as in global named functions.

<calc()> = calc( <calc-sum> ) <calc-sum> = <calc-product> [ [ '+' | '-' ] <calc-product> ]* <calc-product> = <calc-value> [ '*' <calc-value> | '/' <number> ]* <calc-value> = <number> | <dimension> | <percentage> | ( ...

Other than in ordinary C / C++ , the Arduino IDE allows to call a function before it is defined. In .cpp files, you have to define the function, or at least declare the function prototype before you can use it. In an .ino file, the Arduino IDE creates such a prototype behind the scenes. Arduino ...

val (|>) : 'a -> ('a -> 'b) -> 'b val (@@) : ('a -> 'b) -> 'a -> 'b

MD5 and SHA1 are insecure and should be avoided. The examples exist for educational purposes and due to the fact that legacy software may still use these algorithms.
