I created a card shuffling program and it works fine. However, for my project I
am to place the shuffling part of my code in a separate script as a subroutine.
I am to remove the code
that does the shuffling and include it as another function in
obj13-lib.pl. So I did this and after the first "hand" is dealt, call the
shuffling function again before dealing another, different hand.
I call it obj-lib.pl and my main script obj13.pl.
I did put it together but my obj13.pl script is not shuffling my cards and I
need to print out two sets of five elements. And I was not able to get it to
print out 2 sets of five elements.
Where am I going wrong? Looking for some help and a point in the right
direction. Thanks everyone.
Below is my code:
obj13.pl
#!/usr/bin/perl
require 'obj13-lib.pl';
my @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");
print "the top five cards are @startingdeck[0..4]\n";
#_END_ _________________________________________________________________________
My second library script code here is called on to complete my shuffle program:
obj13-lib.pl
#!/usr/bin/perl
sub shuffle(){
my @right;
my @left;
SHUFFLE:
unshift @left, pop @startingdeck for 1..26;
@right = @startingdeck;
@startingdeck = ();
while(@left or @right){
if (rand() < 0.5){
@left and push @startingdeck, shift @left
}else{
@right and push @startingdeck, shift @right
}
};
rand() < 0.9 and goto SHUFFLE;
}
1;
