This is very efficient; just keep in mind that $thing i

This is entirely correct.
But for those of you who prefer a more explicit syntax, you can put any
expression into scalar context with the "scalar" keyword. For my own
tast
A cool control structure in perl is the for or foreac loop. With it you
don't need to know the size of the array you can just
for my $thing (@A) {
#do stuff with $thing
}
If you're familiar with shell syntax this is kinda like the 'for i in list'
construct.

First part:
You get the size of an array by using it in a scalar context.
Sounds complicated?
Scalar context means that the left side of an assignment is a
scalar. So you just write:
$size = @a;
and you get the size of the array @a.
Another method would be to get the index of the last element a
while($ansNum < $numOfAns)
where $ansNum starts at zero and is incremented until it is at
$numOfAns(from the split line above, it's value should represent the number
of elements in @A). This all works, but I would like to improve it and make
it so that the user making the text file
