Program Plan Intro
Iterative Factorial
Program Plan:
- Include the required header files.
- Declare the necessary function prototype and constants.
- Define the “main()” function.
- Declare the variable “value” for storing the number.
- Get the input from the user.
- Call the method “calfactorial()” to compute the factorial of the given number.
- Computed result gets displayed.
- Define the “calfactorial()” method
- Declare the necessary variables.
- Use loop to iterate and compute the factorial of the given number.
- Return the value after computing.

Recursive Power FunctionWrite a 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 that the exponent is a nonnegative integer. Demonstrate the function in a program.

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

- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forwardJAVA CODE ONLY AND PROVIDE OUTPUT SCREENSHOT PLEASEarrow_forwardProblem Statement for Recursive Sum of Numbers Program Here is a simple recursive problem: Design a function that accepts a positive integer >= 1 and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 10 is passed as an argument, the function will return 55. Use recursion to calculate the sum. Write a second function which asks the user for the integer and displays the result of calling the function. Part 1. Understand the Problem To design a recursive function, you need to determine at least one base case (the base case returns a solution) and a general case (the general case calls the function again but passes a smaller version of the data as a parameter). To make this problem recursive think about it like this: If the integer is 1, the function will return 1. If the integer is 2, the function will return 1 + 2 = 3. If the integer is 3, the function will return 1 + 2 + 3 = 6. . . . For this problem, we will be sending in the "last"…arrow_forward
- Question 1 Not complete Marked out of 1.00 Flag question Write a recursive function named count_non_digits (word) which takes a string as a parameter and returns the number of non-digits in the parameter string. The function should return 0 if the parameter string contains only digits. Note: you may not use loops of any kind. You must use recursion to solve this problem. You can assume that the parameter string is not empty. For example: Test Result print(count_non_digits ('123')) print(count_non_digits ('2rPTy5')) print(count_non_digits ('hello world')) 11 Precheck Check 0 4 Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) 1arrow_forwardRecursive PrintingDesign a recursive function that accepts an integer argument,n , and prints the numbers 1 up through n .arrow_forwardWrite a recursive function that finds factorial.
