( #3333=superdoc: print w/replies, xml ) Need Help??
Hi, I am trying to understand how the push and pop functions work in Perl. Here is the script I have written:
#!/usr/bin/perl use warnings; use strict; my @array = qw(Book Novel Magazine Guide); print "\@array has @array so total:",scalar @array,"\n"; push @array,"LFY"; print "Now we have @array\n"; shift @array; print "Now we have @array\n"; my $saved = pop @array; print "Now we have @array and I have saved $saved\n"; unshift @array, "LFY"; print "Now we have @array\n";
And here is the output:
C:\perl>perl @array has Book Novel Magazine Guide so total:4 Now we have Book Novel Magazine Guide LFY Now we have Novel Magazine Guide LFY Now we have Novel Magazine Guide and I have saved LFY Now we have LFY Novel Magazine Guide
Its working like expected, but just wanted to know if its a good practice to do my $saved = pop @array or is there a better way to do it? Are there any other suggestions you would have? I know this is a very simple script, no rocket science but just wanting to ensure that I pick up the correct habits early.
