Question: Exercise 5 . 4 Write a recursive function called power ( ) that takes a double x and an integer n and that returns x

Exercise 5.4 Write a recursive function called power() that takes a double x and
an integer n and that returns x^n
Hint: a recursive definition of this operation is power (x, n)= x * power (x, n-1).
Also, remember that anything raised to the zeroeth power is 1.
