Beginner's Guide To Travel With Perl - Part 9

Sorting:

There is a built-in sort function/subroutine in Perl for sorting array elements. This is done by just writing "sort @name_of_the_array;". But it sorts the elements alphabetically according to their ASCII value. This sort function sorts lexically
Example:

use strict;
main(@ARGV);
sub main
{
    my @arr = ("abc", "abcd", "defg", "def", "ijklm", "ijkl", "nop", "nop", "aaa", "AAA");
    print "before sort : @arr\n";        #before sort : abc abcd defg def ijklm ijkl nop nop aaa AAA
    @arr = sort @arr;
    print "after sort : @arr\n";        #after sort : AAA aaa abc abcd def defg ijkl ijklm nop nop
}

Programming with C Tutorial - Part 1

Lists in HTML:

Lists are of two kinds. They are -
                                               1. ordered list
                                               2. unordered list

For unordered list, <ul> tag is used - <ul> for starting and </ul> for ending the tag. ul stands for "unordered list".
For ordered list, <ol> tag is used - <ol> for starting and </ol> for ending the tag. ol stands for "ordered list".

<li> tag is used for each list element - <li> is for starting and </li> for ending.

Formatting Text:
 
While typing in a word processor (i.e. Microsoft Office or Open Office), we can write our text with different formatting. In HTML, we can also do the same. Let's say something about the formatting.

• Bold: "<b>" tag is used. "<b>" for start and "</b>" for end;
• Strong: "<strong>" tag is used. "<strong>" for start and "</strong>" for end;
