push() & pop()

• push() adds an item to end of the array

• pop() removes an item from the end of array

@flintstones = ("fred","wilma");

push(@flintstones, "barney");

push(@flintstones, "betty"); # ("fred","wilma","barney","betty")

$a = pop(@flintstones);

# $a set to "betty", array now holds: ("fred","wilma","barney");
