Program Plan Intro
Recursive function:
- Recursive function is a function that calls itself during execution.
- It enables the function to repeat itself several times and outputs the result and the end of each iteration.
- Recursive programs are common in computer science since it allows programmers to write efficient programs using less amount of code.

Assume that exponent is an integer greater than or equal to 1.  Then, write a demo program that uses the power function and test it out for a number of inputs.  Hint: The recursion step would use the relationship baseexponent = base * baseexponent–1  and the terminating condition occurs when exponent is equal to 1 because base1 = basearrow_forwardQUESTION 6 A proper recursive solution requires at least two parts: a recursive function that calls the recursive function with a smaller problem, and a base, or stopping case.

Which of the features is not valid for a recursive function. Select one: a. The Recursive calls can be more then one b. The Recursive Call – the function calls itself with an input which is a step closer to the stop condition c. The Stoping Conditions can be more than one d. The Recursive call is optional. e.
