Chapter 13, Problem 4PE
Program Plan Intro
Sum of Numbers
- Define the “main()” function:
- Initializes the variable “number” is “0”
- Check the value of “number”
- If it is less than or equal to “0”, then get the input from the user and store it to the variable “number”.
- Call the function “sumNumbers()” and pass the argument “num”.
- Display the result on the output screen.
- Define the “sumNumbers(num)” function:
- Check the value of “num”
- If it is equal to “0”, then return “num”
- Otherwise, call the function “sumNumbers()” to recursively perform the addition operation.
- Check the value of “num”
- Call the “main()” function.

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_forward(Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:arrow_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
- Design a function that accepts an integer argument and returns the sum of all the integers from 1up to the number passed as an argument. For example, if 50 is passed as an argument, thefunction will return the sum of 1, 2, 3, 4, . . . 50. Use recursion to calculate the sum.arrow_forward*C Language The greatest common divisor of integers x and y is the largest integer that divides both x and y. Write a recursive function GCD that returns the greatest common divisor of x and y. The GCD of x and y is defined as follows: If y is equal to zero, then GCD(x, y) is x; otherwise GCD(x, y) is GCD(y, x % y) where % is the remainder operator.arrow_forwardRecursive PrintingDesign a recursive function that accepts an integer argument,n , and prints the numbers 1 up through n .arrow_forward

In the main function asks the user to enter a number then check if it's palindrome or not using the function you created previously.arrow_forwardJAVA CODE ONLY AND PROVIDE OUTPUT SCREENSHOT PLEASEarrow_forward

Write the recursive function that calculates the total amount of money at the end of the maturity date, based on the condition below. The parameters of the function: capital, initial interest rate and maturity date(months) Note: Codes should be written in C programming language.arrow_forward2. Sum: a recursive function that computes the sum of integers 1, 2, 3, …., n for a given number n. So Sum(6) should return 1 + 2 + 3 + 4 + 5 + 6 , i.e. 21.sum(n) = n + sum(n-1)arrow_forwardPython 6. Sum of Numbers Design a function that accepts an integer argument and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 50 is passed as an argument, the function will return the sum of 1, 2, 3, 4, ...50. Use recursion to calculate • the sum.arrow_forward
