A single line comment starts with two hyphens (--) and extends up to the end of the line. Example :
-- This process models the state register
process(clock, aresetn)
begin
if aresetn = '0' then -- Active low, asynchronous reset
state <= IDLE;
elsif rising_edge(clock) then --...
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

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...

A character type is an enumeration that includes a character literal:
type Roman_Numeral is
('I', 'V', 'X', 'L', 'C', 'D', 'M', Unknown);`
If you're accepting user input for folder paths, you might need to check for trailing backslashes (\) before building a file path. The FSO.BuildPath method makes this simpler:
Const sourceFilePath As String = "C:\Temp" '<-- Without trailing backslash
Const targetFilePath As Strin...
In this example you will explore how to export the following data from Acumatica ERP in batches via the REST Contract-Based API:
stock items existing in the application in batches of 10 records
all sales orders in batches of 100 records
To export stock items in batches of 10 records with mult...
Once using is used to introduce the name cout from the namespace std into the scope of the main function, the std::cout object can be referred to as cout alone.
#include <iostream>
int main() {
using std::cout;
cout << "Hello, world!\n";
}
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...
// gets the Class objects from the net.mminecraft.server package with the given name
public Class<?> getNmsClass(String name) throws ClassNotFoundException {
// explode the Server interface implementation's package name into its components

Parameters can be marked as optional by giving them a default value. Optional parameters can be omitted when calling the function.
string greet (string name, string language = "English") {
if (language == "English") {
return @"Hello, $name!";

Value types (structures and enumerations) are passed by value to functions: a copy will be given to the function, not a reference to the variable. So the following function won't do anything.
void add_three (int x) {
x += 3;
}
int a = 39;
add_three (a);
assert (a == 39); // a is still 39...
int sum (int x, ...) {
int result = x;
va_list list = va_list ();
for (int? y = list.arg<int?> (); y != null; y = list.arg<int?> ()) {
result += y;
}
return result;
}
int a = sum (1, 2, 3, 36);
With this function, you can pass as many int as you w...

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...
Ada offers a wide variety of generic parameters which is difficult to translate into other languages. The parameters used during instantiation and as a consequence those on which the generic unit may rely on may be variables, types, subprograms, or package instances, with certain properties. For exa...
To flatten multidimensional array into single dimension, flatMap advance functions is used. Other use case is to neglect nil value from array & mapping values. Let's check with example:-
Suppose We have an multidimensional array of cities & we want to sorted city name list in ascending orde...
Firebase handles notifications differently when the app is in background (killed process) and when in foreground (active).
When your app is in the background, notification messages are displayed in the system tray, and onMessageReceived is not called. For notification messages with a data payload...
Narrow character types
The unsigned char type uses all bits to represent a binary number. Therefore, for example, if unsigned char is 8 bits long, then the 256 possible bit patterns of a char object represent the 256 different values {0, 1, ..., 255}. The number 42 is guaranteed to be represented b...
