Since as an array is a comma-delimited list of values you can easily combine two arrays with the merge() function. $dash_delimited_monthlist = join('-', = join(' is followed by ', "$Months\n" Print can use the join() function to rejoin elements of an array into a long scalar string, with an optional delimiter. You can use the split() function to split a long string into separate array elements, using a value as a delimiter string. Print "winter months in Brazil are: # Jun Jul Aug The specification of a slice must be a list of comma-delimited valid index numbers, or using the range operator.Įxamples: = qw/Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov = "winter months in Canada are: # Dec Jan Feb My array is: an array is selecting more than one element from an array to create another array. remove element from the beginning of the "5. add element at the beginning of the "Avocado") define initial array = ("Apple","Banana","Carrot") add element or elements into the beginning of the arrayĮxamples: # 1.$shifted = delete and return the first element of the array.$popped = delete and return the last element of the array.element): add element or elements into the end of the array.Perl offers many useful functions to manipulate arrays and their elements: Print "Size: ",scalar "Index of last array element: = () The scalar context is refered to by scalar The last array element is refered to by $#array. The size or length of the array can be evaluated by the scalar context of the array or by using the scalar variable value of the last array element. Print "number of month 2 is $month_numbers\n" # 2 to assign sequential values to array elements. Perl supports a shortcut for sequential letters or numbers. # an array of string elements made of the original string delimited by = qw/Perl is a great scripting language/ This will select elements from the end of the array. # Direct assignment of an element with a specific index.Īccessing array elements can be done with a negative index. The index of the first array element is 0.įor example: # Multiple elements value assignment, which creates an array with four elements, some numeric and some = (25, "John", "Mary", -45.34) To refer to a single element of an array, the variable name must start with a $ followed by the index of the element in square brackets ( ). The array variable name begins with the symbol. Perl array variables store an ordered list of scalar values.
