4. Write a complete program, including headers and directives (i.e. begin with #include). Implement a program that computes the alternating sum of the numbers input by the user. Your program will ask user to type in numbers until the user input an non-number. Then, store all the numbers in a vector called myvector (The non-number user input should not appear in myvector). And then, write a function called alternating_sum, which will do the math of alternating sum on a vector. Call the function on myvector, and print the result out on console. For example, if the user input 4.6 3 2 8.9 0 4 Q, then the vector should contains 4.6, 3, 2, 8.9, 0, 4 and it will compute 4.6 - 3+2 - 8.9 +0 – 4. The output on console should be "The alternating sum is -9.3" Hint1: You don't need #include in this problem Hint2: You can assume the only character (letter) the user may input in 'q' or 'Q'. Note: Do NOT use arrays or pointers. Use vectors instead, if needed.

You are tasked with helping write part of an exciting new word-guessing game, “Durdle”. The game is one in which a player attempts to guess a five-letter word in successive guesses. In this problem and the next one, we will build an implementation of this word-guessing game. First, to support this game, we will write a function named durdle_match(guess, target) that takes in two strings - a player’s guess, and the target word that the player is attempting to guess. Each of the given words is five letters long. This function should return a five-letter string consisting of the letters B, G, and Y that has a meaning associated with the guess as follows: B: This letter in the guess does not appear in the target string Y: This letter in the guess appears in the target string in another location G: This letter in the guess appears in the same location in the target string
PLease! in c++ Write a function named “getNonNegativeSum” that takes in 4 input parameters: -a pointer to thearray of integers-its size, -the index tostart the sum from -the count of how many numbers from that starting index It will return the sum of all values from the startingindex with the number count of how many. It will add to the sum if the number in the array is positiveand skip all negative values. If there is an error in the indexor not enough numbers to count, it will return -1. For example,int numList[] = {10, 20, -1, 30}; If the starting index is 1 and the count of 3, it will return 50 If the starting index is 2 and the count of 2, it will return 30 If the starting index is -1 and the count of 2, it will return -1 If the starting index is 2and the count of 5, it will return -1.int priceList[] = {10, 20, 30, -1, 40}; If the starting index is 0, and the count is 1, it will return 10 If the starting index is 1, and the count is 3, itwill return 50 If the starting index is 0,…
Your task is to implement a variation of the classic word game Hangman, which involves playersguessing the letters in a word chosen at random with a finite number of guesses. While there arealternate versions such as category Hangman and Wheel of Fortune, which involve playersguessing idioms, places, names and so on, we will be sticking with the traditional version. Requirements:You will implement a function called main that allows users to play an interactive hangman gameagainst the computer. The computer should pick a word, and players should then try to guess lettersin the word until they win or run out of guesses.Here is the overarching behaviour we expect:1. The program should load a list of available words from the text file provided. Note thatthe file you have been given contains words in lowercase.2. The computer should then select a word at random from the list at random.3. The user is given a certain number of guesses at the beginning.4. The game is interactive; the user…
Define a function named GetWordFrequency that takes a vector of strings and a search word as parameters. Function GetWordFrequency() then returns the number of occurrences of the search word in the vector parameter (case insensitive). Then, write a main program that reads a list of words into a vector, calls function GetWordFrequency() repeatedly, and outputs the words in the vector with their frequencies. The input begins with an integer indicating the number of words that follow. Ex: If the input is: 5 hey Hi Mark hi mark the output is: hey 1 Hi 2 Mark 2 hi 2 mark 2 Hint: Use tolower() to set the first letter of each word to lowercase before comparing. The program must define and use the following function:int GetWordFrequency(vector<string> wordsList, string currWord) write code in c++

PYTHON!!! Write a function called number_matrix(r,c) that takes two parameters r and c and PRINTS ON THE SCREEN a matrix of numbers as follows: 1 2 3 4 5 .... 2 3 4 5 6 .... 3 4 5 6 7 .... . .. In this pattern, each row contains c numbers and there are r rows. For example, number_matrix(4,3) results in: 1 2 3 2 3 4 3 4 5 4 5 6 Note that you shouldn't be printing anything other than the required matrix of numbers. Even empty strings may invalidate your answer . """ def number_matrix(r,c):

write a python code named get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases)
