Your employer needs a
program that analyzes the monthly sales figures for each
division.
Write a Python program that allows the user to enter a series of
numbers and places the numbers (not string values) in a list. Each
number entered by the user is the monthly sales amount for one
division. Use a sentinel-controlled loop to get input from the user
and place each value entered into the list as long as the value is
not negative. As soon as any negative value is entered, stop the
loop (without putting that illegal value into the list).
One objective of this assignment is to apply algorithms we have studied to solve problems. You will do this by writing a function definition to implement each algorithm. Every function must get information only from its parameters, not from "global" variables. Several of these tasks can also be accomplished with built-in functions. In those cases, your code should demonstrate both approaches and show that the results are the same.
Add code to your program to do the following:
Thank you for helping me, my good sir :) I will thumb up lightning speed.

Write a program that allows the user to enter a series of exam scores. The number of scores the user can enter is not fixed; they can enter any number of scores they want. The exam scores can be either integers or floats. Then, once the user has entered all the scores they want, your program will calculate and print the average of those scores. After printing the average, the program should terminate. You need to use a while loop...
LANGUAGE = C i. Write a program that takes int numbers from user until user gives a sentinel value (loop terminating condition). Sort the numbers in ascending order using Insertion sort method. Sorting part should be done in different function named insertionSort(). Your code should count the number of swaps required to sort the numbers. Print the sorted list and total number of swaps that was required to sort those numbers. (4 marks) ii. In this part take another number...

/* I'm trying to write this program here but my problem is getting the program to save the user input to "int data" but cannot because it is part of the struct. What do I have to do in order to get this to work? (Language is C++) Write a program that prompts the user to enter numbers on the screen and keep adding those numbers to a linked list. The program stops when user enters -999. Hint: Use a...
Total Sales Design a program that asks the user to enter a store’s sales for each day of the week. The amounts should be stored in an array. Use a loop to calculate the total sales for the week and display the result. Need: variable lists, IPO Chart, pseudocode, Flowchart, and working Python code. 2.

Write a Java program to meet the following requirements: 1. Prompt the user to enter three strings by using nextLine(). Space can be part of the string). ( Note: your program requires using loop: for-loop, while-loop or do-while-loop to get the input String ) 2. Write a method with an input variable (string type).The method should return the number of lowercase letters of the input variable. 3. Get the number of the lowercase letters for each user input string by...
Steps: Write a program that upon getting mass value from user, converts it to energy using Einstein’s mass-to-energy conversion equation. You must write a function to calculate energy. Writing the whole thing in main will not get any credit. Note: Conversion equation=> e = m x c^2 Please do these steps: 1-Draw flowchart diagram or write the pseudocode 2-Write your code 3-Run the code 4-Test for all possible inputs!
use C++ to write the following program. needs to ask the user for n The user must put in those 5 values, probably using a for loop. NOTE: You can assume the number of values to be entered is 5. My attempted program below: (not correct, but just a basis) 4. Larger Than n In a program, write a function that accepts three arguments: an array, the size of the array, and a number n. Assume that the array contains...
