Common examples of array slicing are extracting a substring from a string of characters, the "ell" in "hello", extracting a row or column from a two-dimensional array, or extracting a vector from a matrix. Depending on the programming language, an array slice can be made out of non-consecutive
The following list contains syntax examples of how a range of element of an array can be accessed. In the following table: first – the index of the first element in the slice; last – the index of the last element in the slice; end – one more than the index of last element in the slice; len – the length of the slice (= end - first)
The documentation is bundled with Perl in its own format, known as Plain Old Documentation (pod). Some distributions, such as Strawberry Perl, include the documentation in HTML, PDF, and pod formats. perldoc is also the name of the Perl command that provides "access to all the documentation that comes with Perl", from the command line.
Perl borrows features from other programming languages including C, sh, AWK, and sed. [1] It provides text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools. [16] Perl is a highly expressive programming language: source code for a given algorithm can be short and highly compressible. [17 ...
Perl programmers may initialize a hash (or associative array) from a list of key/value pairs. If the keys are separated from the values with the => operator (sometimes called a fat comma ), rather than a comma, they may be unquoted (barewords [ 5 ] ).
In Go, typed variadic arguments are simply collected in a slice. The caller can explicitly pass in a slice in place of the variadic arguments, by appending a ... to the slice argument. This can only be done for a variadic parameter. The caller can not apply an array of arguments to non-variadic parameters, without using reflection..
Serve it on a slice of toasted whole-wheat bread, on crackers or with crisp veggies for an easy lunch. View Recipe. High-Protein Tomato, Mozzarella & Arugula Sandwich.
Perl Data Language (abbreviated PDL) is a set of free software array programming extensions to the Perl programming language. PDL extends the data structures built into Perl, to include large multidimensional arrays , and adds functionality to manipulate those arrays as vector objects.
