Question
How will you sort an array
Answers
The sort() function sorts each element of an array according to the ASCII Numeric standards. This function has the following syntax −

sort [ SUBROUTINE ] LIST

This function sorts the LIST and returns the sorted array value. If SUBROUTINE is specified then specified logic inside the SUBTROUTINE is applied while sorting the elements.

#!/usr/bin/perl

# define an array
@foods = qw(pizza steak chicken burgers);
print "Before: @foods
";

# sort this array
@foods = sort(@foods);
print "After: @foods
";

This will produce the following result −

Before: pizza steak chicken burgers
After: burgers chicken pizza steak   Your Comment
