Extracted text: Exercise 2: Write a function that takes the following prototype: void f1(double x, int N, double& Z); The function accepts a positive double number x and positive integer N, and returns the result of the following expression through the reference variable Z as a double number: All divisions are real, floating-point divisions. Write a main() function to test the working of fl(). The main() asks the user to input value of a positive double variable ( x) and a positive integer (N). It then calls fl() and store the result in the variable Z. All printouts should be done in the main().
