7- There are important differences between values that are printed and output values. Consider the followin function definitions, and assume they are in three different M-files: function [] = f(x) disp(x); end function result g(x) result = 2*x; end function output h(x) result = 3*x; end • What is the output when the following commands are typed in the MATLAB command window? (a) >> f(1) (b) >> g(1) (c) >> h(1) (d) >> x = f(1) (e) >> x = g(1) (f) >> x = h(1) (g) >> disp(g(1)) (h) >> disp(h(1))

3- Write a Matlab function file that asks the user to enter the student's result in first midterm exam, second midterm exam, and final exam, then calculates and display the student's total result. ASsume each midterm exam counts for 30% and the final exam counts for 40%.
Please use Python for this question. Please format code properly when answering the question. Write a standalone function partyVolume() that takes accepts one argument, a string containing the name of a file. The objective of the function is to determine the Volume object that is the result of many people at a party turning the Volume up and down. More specifically: the first line of the file is a number that indicates the initial value of a Volume The remaining lines consist of a single character followed by a space followed by a number. The character will be one of ‘U” or ‘D’ which stand for “up” and “down” respectively. The function will create a new Volume object and then process each line of the file by calling the appropriate method of the Volume object which changes the value of the Volume. The function then returns the final Volume object. Guidelines/hints: This is a standalone function, it should NOT be inside (indented within) the class. It should be listed in…
Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements in c++ : Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each…
Need help in creating a C(NOT C+ OR C#) function that will help split a string present in a Text file. Conditions are that the length of the characters of the words can vary from 7 to 10 maximum and it would be done to random words. For example if the string is "Pedestal -the base or support on which a statue" I want the function to return "Pedestal" and " -the base or support on which a statue" separately. Again the words can vary from 7 to 10 characters but after the word, there is a gap and then there is the definition, which I need to separate. In the function I cant use break, continue exit etc.
Assignment: Use OOP to implement certain details and requirements for the assignment. The lab is about donkey kong characters and their statistics and information which is provided on a Monkey.txt file that must be read in. Some information of monkeys is below which will be used: Most species are arboreal, using all four limbs to leap from tree to tree. They can sit upright and stand erect. Most species run along branches rather than swinging arm over arm like apes. Monkeys are highly social omnivores, organized in clans as large as several hundred individuals headed by an old male. The underlines are at least behavior (member functions) that you are asked to add to your OOP program such as Leap(string, string), Sit(), Walk(), Swing()... Here are some descriptions of a monkey that must apply to your program. The information from the Monkey.txt file will be used along with the format below. Name Sit Walk Swing Leap Jump Banana Year…
Use Python 3 for this question. Do the sentiment analysis based on a text file which contains numerous tweets in its raw text format. All tweets collected in this file contains a key word specified by the instructor. The key word being used is “Trump”. You can use the raw tweets file provided by the following link: tinyurl.com/46ntt3a5. You will need to convert this to a .txt file for this assignment. Your raw tweets file size at least needs to be 350K. After you have the raw tweets file ready, you need to perform the following tasks in a Jupyter notebook file. First you need to clean up the tweet file content to the best you can. For each word that is not a “stop word” (and, the, a, is, as, …), assign a value +1 for positive sentiment or a value -1 for negative sentiment. A list of “positive” words will be provided to you. You can easily find a list of “stop words”, and a list of “negative” words online. For the words that is not in positive/negative/stop words, count as ‘others’.…
Create a new file in c++. In this lab, you will add some functionality to the table ofmenu. Your boss (me) has decided that letters should be used for menu items instead of digits (because there are more alpha characters than numeric ones, so more additional menu items could be added in the future). We all know that programmers are lazy, but so are most users! So, the user should be able to enter either uppercase (A) or lowercase (a) for their menu selection. Also, it is important to let the user know if they entered an invalid choice. Write a program that displays the following menu and prompts the user for a selection. Once the selection has been made, display the selection back to the user. Then, ask the user for two numbers and perform the selected operation (+, -, *, /). Display the results back to the user (e.g. 2 + 3 = 5). When dividing, display an error message if the second number is 0. A) Add two numbers B) Subtract two numbers C) Multiply two numbers D) Divide two…
In this and the following two exercises (8.10 and 8.11), you will carry out some simple processing on data in a file. Each line of the file has two integer values separated by a comma; there are no spaces. The first value is the weight of an individual (in pounds) and the second value is the height of the individual (in inches). The aim of the exercise is to construct a program that will compute the average weight and height. The name of the file is "data.txt". The data file looks as follows:
Use the Bash shell for the completion of this project.Develop a shell scripting application that allows the user to perform some advanced mathematicaloperations. Task 2: Find the terms of any linear sequence given by the rule Term = a*n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.

Hi, I have posted this question before but the solution am getting is not what I want. Note: Please follow the instructions I posted before the question, let me know if there is an issue. Instruction: Please write these problems in javascript. 1. You are to have two javascript files: a. your problem javascript and b. your test javascript file that verifies the function that was written in your problem javascript 2. The implementation for your 5 JavaScript functions must be completed within your - problems.js file. 3. Your Problem JavaScript functions file must be configured for strict mode (“use strict”) The pages that follow provide the description of the 5 JavaScript functions that you must implement Questions 1. Description a). You are to develop a JavaScript file (problems.js) that contains the implementation of 5functions. Each function is represented as one step, b). Each function is independent and solves a unique problem, as such, treat and implement each function in…
