Hello everyone,
I am new to Perl and I am having some issues getting a script to work. I have to create a script that uses an array of 52 cards, "shuffles" the cards (using loops with the pop, shift, and push commands), and prints out the top five. This is not a randomizing of the array just a rearrangement of the array. I have been able to get it to rearrange the array, but not with the result that I would like. I have been working on this for a week and have been running in circles! :wall:
Thank you all for your help.
Here is the code that I have been given to start:
#!/usr/bin/perl
@startingdeck = ("A H","2 H","3 H","4 H","5 H","6 H","7 H","8 H",
"9 H","10 H","J H","Q H","K H",
"A D","2 D","3 D","4 D","5 D","6 D","7 D","8 D",
"9 D","10 D","J D","Q D","K D",
"A C","2 C","3 C","4 C","5 C","6 C","7 C","8 C",
"9 C","10 C","J C","Q C","K C",
"A S","2 S","3 S","4 S","5 S","6 S","7 S","8 S",
"9 S","10 S","J S","Q S","K S");
And here is the instructions that I have been provided to accomplish this objective:
Using pop, shift, push, and the starting code below, write a script that sufficiently "shuffles" a simulated deck of cards before printing the top five cards. Save this script in your home directory as obj10.pl. The goal of this objective is to familiarize yourself with these three functions while using loops and to use them together to rearrange the array but not a randomly shuffled array.
Here is the latest script that I have come up with:
#!/usr/bin/perl
@startingdeck = ("A H","2 H","3 H","4 H","5 H","6 H","7 H","8 H",
"9 H","10 H","J H","Q H","K H",
"A D","2 D","3 D","4 D","5 D","6 D","7 D","8 D",
"9 D","10 D","J D","Q D","K D",
"A C","2 C","3 C","4 C","5 C","6 C","7 C","8 C",
"9 C","10 C","J C","Q C","K C",
"A S","2 S","3 S","4 S","5 S","6 S","7 S","8 S",
"9 S","10 S","J S","Q S","K S");
for($i=0 ; $i < 26 ; $i++){
$left = pop(@startingdeck);
push(@shuffled,$left);
$right = shift(@startingdeck);
push(@shuffled,$right);
}
foreach $card (@shuffled){
print "$card\n";
}
Here is the result of this script:
I am just working on the rearranging of the array right now, and still need to add the commands to print the top 5.
