a. Suppose that the caller has variables int mylnt and float myFloat whose values are 20 and 4.8, respectively. What are the values of mylnt and myEloat after return from the following function call? Demo(mylnt, muEloat); mvlnt: mvEloat: b. Also, describe what happens in MEMORY when the Demo function is called. Think about the by reference and by value parameters.

Over the years, people have created a few nicknames for me. One that sticks without me telling me to call me that name is "Denck." It works great with anyone whose name ends with an "er". We are going to create a function called "nickName" which takes in one parameter. This parameter stores the name you want to create the nickname for. If the name ends with an er, return the name with the er removed. If the name does not have an er then return the full name back to the program.
Can you add a dodamage function to the code? There are options that cause the player to lose lives. We're going to introduce the concept of player health. When the game starts, the player health should be 100. Rather than take an entire life, we want to do damage to the players health and take a life if their health falls below 100. This function should take the players current health as an argument, calculate the new health and return it to the caller. You can choose the amount of damage that is done. *Existing code is below and don't use HTML* const prompt = require("prompt-sync")(); var adventurersName = ["Captain Thomas King","George","Tim","Sarah","Mike","Edward",];var len = 0;var Inventory = new Array(5).fill(" ");Inventory[len++] = "Food";Inventory[len++] = "Wine";Inventory[len++] = "Horses";Inventory[len++] = "Medicine"; var adventurersKilled = 3;var survivors;var numberOfAdventurers = adventurersName.length; survivors = numberOfAdventurers - adventurersKilled;…

Objectives Practice defining functions with parameters. Practice manipulating strings. Implement your own version of Python string methods The provided file string_functions.py defines several string functions, but does not include the code for them. Add code to implement functions that are equivalent in behavior to the corresponding built-in Python string function. Every function MUST return a value. Use loops to implement your functions. You cannot use built-in string methods, string functions, or string-operators to implement your functions. Each function is worth a maximum of 10 points. 1. cs110_upper: Takes a string as a parameter and returns it as a string in all uppercase. Hint: Use the ord () function to get the ASCI value of a character. For example, ord ('a') returns the integer 97. You will also need to use the chr (value) function that returns a string of one character whose ASCII code is the integer valus. For example, chr (97) returns the string 'a'. You cannot use the…

Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4.

Please tell me where I get wrong.
post in python please and a coding editor too You are asked to help write a program that will help users purchase cookies. A user will input types of cookies and the number of cookies that they want, and your program will suggest how many boxes that they should order. There are 30 cookies per box, so your goal is to make sure that the user will buy enough boxes so that they will get the cookies that they want. Write a function cookie_order that takes a dictionary as a parameter containing cookie names as keys and numbers of those cookies as values. Have this function return a new dictionary that has cookie names and the number of boxes that should be purchased of each type. Hint: This means if someone wants 31 cookies, they need to buy 2 boxes of cookies of that type. You may want to consider using math.ceil for this problem. Examples: >>> cookie_order({'thin mints': 97}) {'thin mints': 4} >>> cookie_order({'thin mints':34, 'shortbread': 60, 'caramel delites': 71,…
