Starting with VHDL 2008, a comment can also extend on several lines. Multi-lines comments start with /* and end with */. Example : /* This process models the state register. It has an active low, asynchronous reset and is synchronized on the rising edge of the clock. */ process(clock, ...

Starting a new comment (single line or delimited) inside a comment (single line or delimited) has no effect and is ignored. Examples: -- This is a single-line comment. This second -- has no special meaning. -- This is a single-line comment. This /* has no special meaning. /* This is not a si...

Redis provides three commands to count the items within a sorted set: ZCARD, ZCOUNT, ZLEXCOUNT. The ZCARD command is the basic test for the cardinality of a set. (It is analogous to the SCARD command for sets.) . ZCARD returns the count of the members of a set. Executing the following code to add...

Pointers are variables that store the address of another variable.As language feature they are available in several programming languages like, but not limited to : Go C/C++ Ada Pascal C# (available under certain constraints) COBOL FORTRAN To get started with C/C++ pointers , follow thes...

If you do not only wish to display static objects, but have your UI respond to changes to correlating objects, you need to understand the basics of the INotifyPropertyChanged interface. Assuming we have our MainWindowdefined as <Window x:Class="Application.MainWindow" xmlns=&quot...

When writing Gherkin, there may be times in which you want to parameterize your steps for reusability by the engineer who is implementing the test plans. Steps receive parameters through regular expression capturing groups. (Engineering Note: If you do not have matching parameters for each capturing...

type Grade is range 0 .. 15; B : Grade := 11; C : Grade := 8; Avg : Grade := (B + C) / 2; -- Avg = 9

A fixed point type definition specifies a delta, and a range. Together, they describe how precisely real values should be approximated as they are represented by powers of two, not using floating point hardware. Shoe_Ounce : constant := 2.54 / 64.0; type Thickness is delta Shoe_Ounce range 0.00 .....

Decimal fixed point types are typically used in accounting. They are characterised by both a delta and a number of decimal digits. Their arithmetical operations reflect the rules of accounting. type Money is delta 0.001 digits 10; Oil_Price : Money := 56.402; Loss : Money := 0.002 / 3; -- ...

Let's assume you have a ListView wich is supposed to display every User object listed under the Users Property of the ViewModel where Properties of the User object can get updated programatically. <ListView ItemsSource="{Binding Path=Users}" > <ListView.ItemTemplate> ...

This example implements a linked list with many of the same methods as that of the built-in list object. class Node: def __init__(self, val): self.data = val self.next = None def getData(self): return self.data def getNext(self): return self.ne...

If a using-declaration occurs at class scope, it is only allowed to redeclare a member of a base class. For example, using std::cout is not allowed at class scope. Often, the name redeclared is one that would otherwise be hidden. For example, in the below code, d1.foo only refers to Derived1::foo(c...

Sometimes you may want to have some login to determine where the user gets redirected to after submitting a form. Form Requests give a variety of ways. By default there are 3 variables declared in the Request $redirect, $redirectRoute and $redirectAction. On top of those 3 variables you can overr...

Block will capture variables that appeared in the same lexical scope. Normally these variables are captured as "const" value: int val = 10; void (^blk)(void) = ^{ val = 20; // Error! val is a constant value and cannot be modified! }; In order to modify the variable, you need to ...

In the case of a discriminated record type, some of the components are known as discriminants and the remaining components can depend upon these. The discriminants can be thought of as parameterizing the type and the syntax reveals this analogy. In this example we create a type that provide a sq...

A key part of the Reader monad is the ask (https://hackage.haskell.org/package/mtl-2.2.1/docs/Control-Monad-Reader.html#v:ask) function, which is defined for illustrative purposes: import Control.Monad.Trans.Reader hiding (ask) import Control.Monad.Trans ask :: Monad m => ReaderT r m r ask ...

This is an official MATLAB example Consider the following code: month = [1;1;2;3;8;1;3;4;9;11;9;12;3;4;11]; temperature = [57;61;60;62;45;59;64;66;40;56;38;65;61;64;55]; maxTemp = accumarray(month,temperature,[],@max); The image below demonstrates the computation process done by accumarray in...
