Write a program that recursively and iteratively counts down from n. a) Create a void recursive function named countDownR() that accepts an integer n, and progressively decrements and outputs the value of n. b) Create a void iterative function named countDownI() that accepts an integer n, and progressively decrements and outputs the value of n. c) Trace the function when n is 5.   Example Output 5 4 3 2 1 0

Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.
