- 2- The factorial n! of a positive integer n is defined as n! = 1*2*3 . .. * (n-1) * n Where 0! = 1 Write a function to calculate the factorial of a number. Argument: A number n of type unsigned int. Returns: The factorial n! of type long double. Write two versions of the function, where the factorial is • calculated using a loop calculated recursively Test both functions by outputting the factorials of the numbers 0 to 20.Write code that uses any type of loop. The code should continually ask for a user input and sums all user inputs that are divisible by 2. The loop should continue until the user enters a negative number. The code should output the sum a single time once user entry has completed. You may assume all libraries and namespaces have been previously written into the code, you are just writing everything that would go inside the main function (beyond the return 0:).Boolean Function - Pythona) Define a function, isInRange() with an integer parameter, x. This function returns true if the integer number x is in the range (-100, 100). Otherwise, return false.b) Define a main() function, in which a loop will be created to do the following ten times: - Get a random integer, n, in the range (-500, 500).- Call isInRange(x) function to determine and print out if the number n is in the range.c) Call main() function to initiate the tasks to be performed.
- use a while loop instead of for loop for this function you are not allowed to use any of the following: dictionaries or dictionary methods try-except break and continue statements recursion map / filterC++ Coding: Nested Loops Create a constant DIM. Set DIM to 7, and use a nested loop to display the following square matrix output.

Today, we shall pay attention only to the negative ones now. Make a loop that will accept O Test Case 1 random decimal/float numbers. When the user Your Output inputs 0, the loop will terminate and then output No Output the sum of all negative numbers inputted in 3 decimal places. Expected Output Let's code this. Enter a number: 2.4434 Enter a number: -1.3433 Input Enter a number: -2.444 Enter a number: 6.432 1. A series of decimal numbers Enter a number: 0 Sum of all negatives = -3.787 Output The first lines will contain message prompts to input the decimal numbers. The last line contains the sum of all negative numbers with 3 decimal places. O Test Case 2Programming Assignment:Here is a loop that starts with an initial estimate of the square root of a, x, and improves it until itstops changing:while True: y = (x + a / x) / 2 if abs(y - x) < epsilon: break x = ywhere epsilon has a value like 0.0000001 that determines how close is close enough.Encapsulate this loop in a function called square_root that takes a as a parameter, chooses areasonable value of x, and returns an estimate of the square root of a.To test the square root algorithm in this chapter, you could compare it with math.sqrt. Write afunction named test_square_root that prints a table like this:1.0 1.0 1.0 0.02.0 1.41421356237 1.41421356237 2.22044604925e-163.0 1.73205080757 1.73205080757 0.04.0 2.0 2.0 0.05.0 2.2360679775 2.2360679775 0.06.0 2.44948974278 2.44948974278 0.07.0 2.64575131106 2.64575131106 0.08.0 2.82842712475 2.82842712475 4.4408920985e-169.0 3.0 3.0 0.0The first column is a number, a; the second column is the square root of a computed with the[your…#include <stdio.h> int main(){ int a; /* for loop execution */ for ( a = 1; a <= 100; a++){ printf("%d\n",a * a); } return 0; } write a code using while loop that will provide the same output as the code given above.
- 2. Test Scores File: test_scores.py Write pseudocode for the main() part of a program that asks the user to enter 4 test scores between 0 and 100, then displays a JCU grade for each score and also the average test score. When you have written the pseudocode for main, implement your solution in Python code and test it with a range of meaningful data. Remember that we've done the JCU grades question before, so copy your function from that practical code file. Sample Output Score: 3 Score: 50.5 Score: 66 Score: 100 Score 3.0, which is N Score 50.5, which is P Score 66.0, which is C Score 100.0, which is HD The average score was 54.875 Enhancements When you have that working... We asked for 4 scores. Have a look at your code... did you use 4 as a numeric literal or a constant?Change 4 to 3... Did you have to change the program in more than one place?If so, then you've missed one of the things we've taught...As a strong guideline: if you need to use the same literal more than once, you…C++ Vector iteration: Sum of excess. Vector testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.Write a recursive function named largestDigit that accepts an integer parameter and returns the largest digit value that appears in that integer. Your function should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. You must not use any loops; you also cannot use the string type or any library functions. Your function must be recursive. Complete the following file: largestDigit.cpp 2 // You may use this helper function 3 int max(int a, int b) { return a < b ? b : a; } 4 5 int largestDigit(int n) if((n<0) && (n/10 if(n<0) n = 0)) return n; 8 -n; static int maxi 9 n%10; 0) return maxi; maxi = max(maxi, n%10); return largestDigit(n/10); = 10 if((n/10) 11 12 13 14 15 16 } Submit Calling with Arguments Name Arguments Actual Expected pass largestDigit 135725 7 7 pass largestDigit 111211 2 2 fail largestDigit 100000 1 pass largestDigit 4530021 5 pass largestDigit 7639852 fail largestDigit 76352 6 pass…
