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

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

This example will go over the basic structure of a Cucumber feature file in Gherkin. Feature files use several keywords in the basic syntax.
Lets look at the basic keywords:
Feature: this keyword signifies that what follows is a basic description or name of the feature being tested or documented...
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...
As you may have noticed in the example above, we are rewriting the same step multiple times:
Given the user is on the login page
This can be exceptionally tedious, especially if we have more than one given step that is reused. Gherkin provides a solution for this by giving us another keyword to ...
In some cases you may want to rerun the same scenario over and over, substituting out the arguments. In this case, Gherkin provides several new keywords to accommodate this situation, Scenario Outline: and Example:. The Scenario Outline keyword tells Cucumber that the scenario is going to run multip...
For the purposes of documentation, you may want to filter test plans or scenarios by categories. Developers may want to run tests based on those same categories. Gherkin allows you to categorize Features as well as individual Scenarios via the user of Tags. In the example below, notice the above the...
Since Bootstrap 4 is a major rewrite, many of the Bootstrap 3.x class names have changed or been removed. The restructuring of components such as the Navbar, and the introduction of new CSS classes and Flexbox support means that upgrading to 4.x is not a simple conversion process from 3.x.
However,...

A character type is an enumeration that includes a character literal:
type Roman_Numeral is
('I', 'V', 'X', 'L', 'C', 'D', 'M', Unknown);`
These are the “bit fiddling” types. They have logical operators, too, such as xor, and they “wrap around” at the upper bound, to 0 again.
type Bits is mod 2**24;
L : Bits := 2#00001000_01010000_11001100# or 7;
A floating point type is characterised by its (decimal) digits which state the minimal precision requested.
type Distance is digits 8;
Earth : Distance := 40_075.017;
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; -- ...
