while loop iterates through a block of code as long as a specified condition is true. $i = 1; while ($i < 10) { echo $i; $i++; } Output: 123456789 For detailed information, see the Loops topic.

do-while loop first executes a block of code once, in every case, then iterates through that block of code as long as a specified condition is true. $i = 0; do { $i++; echo $i; } while ($i < 10); Output: `12345678910` For detailed information, see the Loops topic.

Assuming we want to modify bit n of an integer primitive, i (byte, short, char, int, or long): (i & 1 << n) != 0 // checks bit 'n' i |= 1 << n; // sets bit 'n' to 1 i &= ~(1 << n); // sets bit 'n' to 0 i ^= 1 << n; // toggles the value of bit 'n' Us...

In Index page change the following: error_reporting(E_ALL | E_STRICT); to error_reporting(E_ALL); Set $_SERVER['MAGE_IS_DEVELOPER_MODE'] = true and uncomment this line (remove the #) #ini_set('display_errors', 1); You can also Set Dev Mode using SetEnv in your .htaccess file To make th...

The minimum required to use Webpack is the following command: webpack ./src/index.js ./dist/bundle.js // this is equivalent to: webpack source-file destination-file Web pack will take the source file, compile to the output destination and resolve any dependencies in the source files.

SP.SOD.executeOrDelayUntilScriptLoaded( function(){ deleteItem(1); }, "sp.js"); function deleteItem(id){ var clientContext = new SP.ClientContext(); var list = clientContext.get_web().get_lists().getByTitle("List Title"); var item = list.getItemById(id); it...

A do-while loop is very similar to a while loop, except that the condition is checked at the end of each cycle, not at the start. The loop is therefore guaranteed to execute at least once. The following code will print 0, as the condition will evaluate to false at the end of the first iteration: i...

You can use Gradle to auto-increment your package version each time you build it. To do so create a version.properties file in the same directory as your build.gradle with the following contents: VERSION_MAJOR=0 VERSION_MINOR=1 VERSION_BUILD=1 (Changing the values for major and minor as you s...

int squareNum (int a) { return a*a; } int : return type squareNum : function name int a : parameter type and name return a*a : return a value (same type as the return type defined at the beginning)

The use of Matlab Coder sometimes denies the use of some very common functions, if they are not compatible to C++. Relatively often there exist undocumented helper functions, which can be used as replacements. Here is a comprehensive list of supported functions.. And following a collection of alte...

There are a few ways to catch multiple exceptions. The first is by creating a tuple of the exception types you wish to catch and handle in the same manner. This example will cause the code to ignore KeyError and AttributeError exceptions. try: d = {} a = d[1] b = d.non_existing_fiel...

Sometimes it is useful to create union types with only one case to implement record-like types: type Point = Point of float * float let point1 = Point(0.0, 3.0) let point2 = Point(-2.5, -4.0) These become very useful because they can be decomposed via pattern matching in the same way as tu...

Singleton Objects Scala supports static members, but not in the same manner as Java. Scala provides an alternative to this called Singleton Objects. Singleton objects are similar to a normal class, except they can not be instantiated using the new keyword. Below is a sample singleton class: object...

During development, when certain code paths must be prevented from the reach of control flow, you may use assert(0) to indicate that such a condition is erroneous: switch (color) { case COLOR_RED: case COLOR_GREEN: case COLOR_BLUE: break; default: assert(0); ...

Any permission required by your application to access a protected part of the API or to interact with other applications must be declared in your AndroidManifest.xml file. This is done using the <uses-permission /> tag. Syntax <uses-permission android:name="string" android...
