Module/Week 2 ASSIGNMENT (INPUT/OUTPUT)The number of permutations of a set of n items taken r at a time is given by the following formulan !⁄r !(n-r)!: where n! is the factorial of n, r! is the factorial of r, and (n-r)! is the factorial of the result of n-r. The factorial of a number n can be solved using the following formula: 〖n!=e〗^(-n) n^n√2πn. If there are 18 people in your class and you want to divide the class into programming teams of 3 members, you can compute the number of different teams that can be arranged using this formula (n !⁄r !(n-r)!). Write a C++ program that determines the number of potential team arrangements. You will need to use the double type for this computation. Use the Lab Template you set-up last week, proper formatting, and appropriate comments in your code. The output must be labeled clearly and formatted neatly. Submit C++ Programming Assignment 2 by 11:59 p.m. (ET) on Monday of Module/Week 2.

Instructions C++ 8-17 A company hired 10 temporary workers who are paid hourly and you are given a data file that contains the last name of the employees, the number of hours each employee worked in a week, and the hourly pay rate of each employee. You are asked to write a program that computes each employee’s weekly pay and the average salary of all employees. The program then outputs the weekly pay of each employee, the average weekly pay, and the names of all the employees whose pay is greater than or equal to the average pay. If the number of hours worked in a week is more than 40, then the pay rate for the hours over 40 is 1.5 times the regular hourly rate. Use two parallel arrays: a one-dimensional array to store the names of all the employees (Name) a two-dimensional array of 10 rows and 3 columns to store the number of hours an employee worked in a week (Hrs Worked), the hourly pay rate (Pay Rate), and the weekly pay (Salary). Your program must contain at least the following…

PART I: Functions – Math Test Write the Flowchart and Python code for the following programming problem based on the pseudocode below. Write a program that will allow a student to enter their name and then ask them to solve 10 mathematical equations. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether the answer was right or wrong, and accumulate the correct values. After the 10 questions are asked, calculate the average correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer. A function that…

Q2) Write a C function called SortTriple that has three integers parameters namely, low, mid, and high. After executing the function SortTriple the function will swap the values of the three parameters so that low store the smallest value of the three values, high stores the biggest value of the three values, and mid store the middle value of the three values. Q3) Write a main function to test your SortTriple will ask the user to enter the three values, then uses SortTriple to reorder the values if required. The main function should print the value in the correct order and a message to indicate if the values were in the correct order or not. Sample Input/Output please enter the low value: 7 please enter the mid value: 2 please enter the high value:4 Values were not in the correct order or place low = 2, mid = 4, high = 7 please enter the low value: 0 please enter the mid value: 5 please enter the high value:21 Values were in the correct order or place please enter the low value: -1…
