Add a new operator

1.

A few homeworks ago, we wrote a recursive program that raises a double x to an integral power n, by dividing n by two repeatedly. For this assignment, we want a version of that program that works with two integers. Just to make things interesting, you should make this version iterative.

Use your solution to the previous problem to add a new operator, $\wedge$, to your calculator. It should raise the first operand to the power specified by the second operand.
