How to sort values of an array with sort() in Perl
okwudili onyejiaku
Overview
In Perl, we can sort an array with the sort() method. It takes a single parameter, the array that needs to be sorted.
Syntax
sort(arr)
Parameters
arr: This is the array we want to sort.
Return Value
It returns a sorted array.
Example
# create arrays
@arr1 = (1, 5, 2, 4, 3);
@arr2 = ("e", "c", "a", "d", "b");
@arr3 = ("Java", "Python", "Perl", "C");
# print arrays before sort
print "Before Sort: \n
\@arr1 = @arr1\n
\@arr2 = @arr2\n
\@arr3 = @arr3";
# sort the arrays
@r1 = sort(@arr1);
@r2 = sort(@arr2);
@r3 = sort(@arr3);
# print arrays again
print "\nAfter Sort: \n
\@arr1 = @r1\n
\@arr2 = @r2\n
\@arr3 = @r3\n";Sort elements in an array
Explanation
- Line 2–4: We create arrays.
- Line 7: We print the array values before sorting.
- Line 12–14: The arrays we created are sorted using the
sort()method. The results were stored in variables@r1,@r2, and@r3. - Line 17: We printed the results to the console after sorting the arrays.
