Tutorial by Examples: int

After receiving the arguments, you can print them as follows: int main(int argc, char **argv) { for (int i = 1; i < argc; i++) { printf("Argument %d: [%s]\n", i, argv[i]); } } Notes The argv parameter can be also defined as char *argv[]. argv[0] may co...

In Python 3 and higher, print is a function rather than a keyword. print('hello world!') # out: hello world! foo = 1 bar = 'bar' baz = 3.14 print(foo) # out: 1 print(bar) # out: bar print(baz) # out: 3.14 You can also pass a number of parameters to print: print(foo, bar, b...

Create a receiver. This class will receive the intent and handle it how you wish. public class AlarmReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // Handle intent int reqCode = intent.getExtras().getInt(&...

The following types are defined as integral types: char Signed integer types Unsigned integer types char16_t and char32_t bool wchar_t With the exception of sizeof(char) / sizeof(signed char) / sizeof(unsigned char), which is split between § 3.9.1.1 [basic.fundamental/1] and § 5.3.3.1 [ex...

In general, most of the objects you would interact with as a user would tend to be a vector; e.g numeric vector, logical vector. These objects can only take in a single type of variable (a numeric vector can only have numbers inside it). A list would be able to store any type variable in it, making...

Every package requires a setup.py file which describes the package. Consider the following directory structure for a simple package: +-- package_name | | | +-- __init__.py | +-- setup.py The __init__.py contains only the line def foo(): return 100. The following setup.py...

For if you have to fine-tune what is published. import { Mongo } from 'meteor/mongo'; import { Meteor } from 'meteor/meteor'; import { Random } from 'meteor/random'; if (Meteor.isClient) { // established this collection on the client only. // a name is required (first parameter) and this...

Using the dateutil library as in the previous example on parsing timezone-aware timestamps, it is also possible to parse timestamps with a specified "short" time zone name. For dates formatted with short time zone names or abbreviations, which are generally ambiguous (e.g. CST, which coul...

public interface IShape { decimal Area(); } public struct Rectangle : IShape { public decimal Length { get; set; } public decimal Width { get; set; } public decimal Area() { return Length * Width; } }

To run a container interactively, pass in the -it options: $ docker run -it ubuntu:14.04 bash root@8ef2356d919a:/# echo hi hi root@8ef2356d919a:/# -i keeps STDIN open, while -t allocates a pseudo-TTY.

Just like char and int, a function is a fundamental feature of C. As such, you can declare a pointer to one: which means that you can pass which function to call to another function to help it do its job. For example, if you had a graph() function that displayed a graph, you could pass which functio...

Actually you can use ReactJS's components in Typescript as in facebook's example. Just replace 'jsx' file's extension to 'tsx': //helloMessage.tsx: var HelloMessage = React.createClass({ render: function() { return <div>Hello {this.props.name}</div>; } }); ReactDOM.rende...

Support for type hinting array parameters (and return values after PHP 7.1) was added in PHP 5.1 with the keyword array. Any arrays of any dimensions and types, as well as empty arrays, are valid values. Support for type hinting callables was added in PHP 5.4. Any value that is_callable() is valid ...

Since PHP objects don't inherit from any base class (including stdClass), there is no support for type hinting a generic object type. For example, the below will not work. <?php function doSomething(object $obj) { return $obj; } class ClassOne {} class ClassTwo {} $classOne= new...

Type hinting for classes and interfaces was added in PHP 5. Class type hint <?php class Student { public $name = 'Chris'; } class School { public $name = 'University of Edinburgh'; } function enroll(Student $student, School $school) { echo $student->name . ' is b...

More complicated tests sometimes need to have things set up before you run the code you want to test. It is possible to do this in the test function itself, but then you end up with large test functions doing so much that it is difficult to tell where the setup stops and the test begins. You can als...

int a = 1; int *a_pointer = &a; To dereference a_pointer and change the value of a, we use the following operation *a_pointer = 2; This can be verified using the following print statements. printf("%d\n", a); /* Prints 2 */ printf("%d\n", *a_pointer); /* Also prints...

The PrettyPrinter utility will 'pretty print' XML documents. The following code snippet pretty prints unformatted xml: import scala.xml.{PrettyPrinter, XML} val xml = XML.loadString("<a>Alana<b><c>Beth</c><d>Catie</d></b></a>") val formatt...

A Broadcast receiver is an Android component which allows you to register for system or application events. A receiver can be registered via the AndroidManifest.xml file or dynamically via the Context.registerReceiver() method. public class MyReceiver extends BroadcastReceiver { @Override ...

This code selects data out of a table: SELECT Column1, Column2, Column3 FROM MySourceTable; This code creates a new table called MyNewTable and puts that data into it SELECT Column1, Column2, Column3 INTO MyNewTable FROM MySourceTable;
