(using c++)

Write 2 Functions called powerIter() and powerRec(), each mothed takes 2 arguments (double n and int p).

powerIter() method returns the value of n to the power of p using an iteration methodology and powerRec() returns the same value using a Recursion methodology.

overload these 2 methods so that if the argument p is omitted, the number n will be sequared.

Write a main method that gets 2 values from the user (n and p) to test these 4 functions
