Recursive Multiplication Program Plan: Define the “main()” function: Initializes the variable “n1” is “0” Initializes the variable “n2” is “0” Check the value of “n1”. If it is less than or equal to “0”, then get the first number from the user and store it to the variable “n1”. Check the value of “n2”. If it is less than or equal to “0”, then get the second number from the user and store it to the variable “n2”. Call the function “multiplyRecursive()” and pass the two arguments “n1” and “n2”. Define the “multiplyRecursive()” function: Check the value of “x” and “y” If it is equal to “0”, then return “0”. Otherwise, call the function “multiplyRecursive()” to recursively perform the addition operation. Call the “main()” function.

Program Plan Intro

Recursive Multiplication

Program Plan:

Define the “main()” function:

Initializes the variable “n1” is “0”

Initializes the variable “n2” is “0”

Check the value of “n1”.

If it is less than or equal to “0”, then get the first number from the user and store it to the variable “n1”.

Check the value of “n2”.

If it is less than or equal to “0”, then get the second number from the user and store it to the variable “n2”.

Call the function “multiplyRecursive()” and pass the two arguments “n1” and “n2”.

Define the “multiplyRecursive()” function:

Check the value of “x” and “y”

If it is equal to “0”, then return “0”.

Otherwise, call the function “multiplyRecursive()” to recursively perform the addition operation.

Call the “main()” function.

Exponent y Catherine Arellano mplement a recursive function that returns he exponent given the base and the result. for example, if the base is 2 and the result is 3, then the output should be 3 because the exponent needed for 2 to become 8 is 3 (i.e. 23 = 8) nstructions: 1. In the code editor, you are provided with a main() function that asks the user for two integer inputs: 1. The first integer is the base 2. The second integer is the result 2. Furthermore, you are provided with the getExponent() function. The details of this function are the following: 1. Return type - int 2. Name - getExponent 3. Parameters 1. int - base 2. int - result 4. Description - this recursive function returns the exponent 5. Your task is to add the base case and the general case so it will work Score: 0/5 Overview 1080 main.c exponent.h 1 #include 2 #include "exponent.h" 3 int main(void) { 4 int base, result; 5 6 printf("Enter the base: "); scanf("%d", &base); 7 8 9 printf("Enter the result: ");…

Problem: Recursive Power Method Design a python function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised, and the exponent. Assume the exponent is a nonnegative integer. Write the main() function to input the required parameters as shown in thesample input/output. Sample Output:Average number of words per line: 26.0Enter a number: 2Enter a positive whole number between 1 and 100: 102.0 raised to the power of 10 is 1,024.00

Python program (recursive function) A recursive function is a function defined in terms of itself via self-referential expressions. This means that the function will continue to call itself and repeat its behavior until some condition is met to return a result. Write a python recursive functionprod that takes x as an argument, and returns the result where, result=1*1/2*1/3*….*1/n Include a screenshot that shows a python program that uses the above function and prints the rounded result to three decimal placesafter prompting the user to enter a number, x. Use x=3. N.B: The code should be included please.
