I'm brand new at perl. Basically all I'm trying to do is make a thing that lists each variable in an array. My logic is that after each time it prints the name of each variable, it increases a different variable which controls which variable it's going to print next. OK that was total jibberish I hope you understood that. Here's an example:
@HappyArray=("Perl","Is","Confusing","Would","Someone","Please","Help"
+,"Me");
$printnumber=-1;
foreach (@HappyArray) {
inc $printnumber 1;
print "$HappyArray[$printnumber]\n";
}
die "Done!\n";
When I run the script, I get this error:
Can't call method "inc" without a package or object reference at line 5.
Isn't $printnumber the object reference??
