Looping through an array with foreach

foreach(@array)

}
It is prettier to assign the element of the array to named variable.
foreach my $element (@array)
{
print $element;
}

To add to the right-side:
@arr = ("a", "b");
push(@arr, "c");
To add to the left-side:
@arr = ("b", "c");
unshift(@arr, "a");
