Description: | For those new to Perl, this script uses the ever-popular
"Ate My Balls" joke to demonstrate simple concepts like
variable assignments, while() loops, printing, simple
array manipulation, and the use of Perl's rand() function.
Consider this Chapter 1 in your quest for Perl skillz. I will post more simple scripts like these as I continue to strengthen my "rabid sloth" style of Perl-Fu. |
#!/usr/bin/perl $a=5; + # Here we make a new variable called "a" to use as a simple loop co +unter. + # Now, we'll create some arrays, and start them off with some fresh + elements. @group=("swarm","heap","load","gang","squad","bunch","cluster","family +","team"); # This is an array, called group. Arrays are designated wi +th in at-symbol (@) prefix. @adjective=("crack-smoking","supple","furious","sexy","hyperactive","i +nquisitive","hot","old","crazy"); @noun=("midgets","Cuban refugees","clowns","bitches","programmers","ba +bies","dogs","hep-cats","apes"); while($a>0) + # This is a simple while-loop construct. It uses the same syntax as + Java, or C, { + # with one exception...You need to enclose even singular expression +s in braces. $index=rand(9); + # This generates a random integer between 0 and 9, and stores it in + $index print( "\nMr. T says, \"Daaaaammmn!!! A @group[$index]"); + # First part of the line is printed here, in this statement. $index=rand(9); + # A new number is generated, and stored in $index. print( " of @adjective[$index]"); + # The n'th element ($index) of the array is printed here. $index=rand(9); + # A new random number is generated and stored in $index. print( " @noun[$index] just ate my balls!!\""); + # The end of the line is printed. $a--; + # Our loop counter is decremented here, and the loop iterates. } print("\n\n"); + # Toss in a few newlines to keep things pretty, and we're all done! |
