Program Plan Intro
Sum of numbers
Program Plan:
- Include the required header files.
- Declare the necessary function prototype and constants.
- Define the main () function,
- Call the method “computesum()” to compute the sum of the given “n” elements.
- The function gets executed in recursive way to compute the sum of the “n” elements that is given.
- Define the “computesum()” method,
- A condition that validates whether the given value is greater than zero.
- If the condition becomes true, the sum gets calculated recursively.
- If the condition becomes false, the value zero gets returned.

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

Problem 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"…

- (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_forwardRecursive PrintingDesign a recursive function that accepts an integer argument,n , and prints the numbers 1 up through n .arrow_forward
