Answer : From php.net... The value of the constant; only scalar and null values are allowed . Scalar values are integer, float, string or boolean values. It is possible to define resource constants, however it is not recommended and may cause unpredictable behavior. But You can do with some tricks : define('names', serialize(array('John', 'James' ...))); & You have to use unserialize() the constant value (names) when used. This isn't really that useful & so just define multiple constants instead: define('NAME1', 'John'); define('NAME2', 'James'); .. And print like this: echo constant('NAME'.$digit); This has changed in newer versions of PHP, as stated in the PHP manual From PHP 5.6 onwards, it is possible to define a constant as a scalar expression, and it is also possible to define an array constant .

Answer : Scalar quantities can be negative. Instead of saying "scalar quantities have only magnitudes," a better description might be that a scalar quantity can be described using only one number per point in space. That number may be positive or negative. In contrast, a vector quantity cannot be described using only one number per point in space. In 3-d space, we need 3 numbers per point in space to describe a vector quantity. The word "magnitude," whether applied to a scalar or a vector or anything else, normally refers to a non-negative number. It is sometimes used to refer to the absolute value of a scalar, and sometimes used to refer to the norm (e.g., length) of a vector. In summary, this is how the words are typically used: Scalar typically refers to a single element of a number field (or a single element per point in space), such as a real number (which can be positive or negative) or even a complex number (this is common in the context of q

Example 1: delete conda from machine conda install anaconda - clean # install the package anaconda clean anaconda - clean -- yes # clean all anaconda related files and directories rm - rf ~ / anaconda3 # removes the entire anaconda directory rm - rf ~ / . anaconda_backup # anaconda clean creates a back_up of files / dirs , remove it # ( conda list ; cmd shouldn ' t respond after the clean up ) Example 2: uninstall anaconda ubuntu # Install anaconda - clean conda install anaconda - clean # start anaconda - clean anaconda - clean -- yes

Example 1: power func in c The function pow ( ) is used to calculate the power raised to the base value . It takes two arguments . It returns the power raised to the base value . It is declared in “math . h” header file . Example 2: fuction power in c int base = 3 ; int power = 5 ; pow ( double ( base ) , double ( power ) ) ;

Example: system was not declared in this scope # include <cstdlib>

Example 1: java split array into two String [ ] array = { "0" , "1" , "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" } ; String [ ] a = Arrays . copyOfRange ( array , 0 , 4 ) ; //<- (targetArray, start, to) String [ ] b = Arrays . copyOfRange ( array , 4 , array . length ) ; Output : a : 0 , 1 , 2 , 3 b : 4 , 5 , 6 , 7 , 8 , 9 Example 2: java split string String yourString = "Hello/Test/World" ; String [ ] strings = yourString . split ( "/" /*<- Regex */ ) ; Output : strings = [ Hello , Test , World ] Example 3: How to split a string in Java String string = "004-034556" ; String [ ] parts = string . split ( "-" ) ; String part1 = parts [ 0 ] ; // 004 String part2 = parts [ 1 ] ; // 034556 Example 4: split method in java public class SplitExample2 { public static void main ( String

Example: android get sdk version if(android.os.Build.VERSION.SDK_INT == android.os.Build.VERSION_CODES.LOLLIPOP){ // Code For Android Version higher equal to LOLLIPOP(21) } else if(android.os.Build.VERSION.SDK_INT > 21){ // Code For Android Version higher than LOLLIPOP(21) } else{ // Code For Android Version lower than LOLLIPOP(21) }

Example 1: how to install composer macos Open a terminal and navigate to your user directory , ie cd / User / < USER_NAME > / Run this command shown below to download Composer . This will create a Phar ( PHP Archive ) file called composer . phar : curl - sS https : //getcomposer.org/installer | php Now we move composer . phar file to a directory sudo mv composer . phar / usr / local / bin / We want to run Composer with having to be root al the time , so we need to change the permissions : sudo chmod 755 / usr / local / bin / composer . phar Next , we need to let Bash know where to execute Composer : nano ~ / . bash_profile Add this line below to bash_profile and save alias composer = "php /usr/local/bin/composer.phar" and then run this command : source ~ / . bash_profile Finally , run : composer - v Example 2: install composer mac curl - sS https : //getcomposer.org/installer | php php composer . phar install mv composer . phar / usr / local / bin /
