DO THIS IN C++

Choice 1: Recursive power function Write a recursive function, power, that takes as parameters two integers x and y such that x is nonzero and returns xY. You can use the following recursive definition to calculate xy. If y >=0: power(x,y) = 1 if y = 0 * if y = 1 * X power(x,y - 1) if y>1. If y> Ensure the correct inputs are entered. Also, write a program to test your function
