- DescriptionWrite a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The date in the output file will be nearly the same as the data in the input file except that you will print the names as last-name, first-name; each quiz score, and there will be one additional number at the end of each line:the average of the student's ten quiz scores.Both files are parameters. You can access the name of the input file with argv[1]. and the name of the output file with argv[2].The output file must be formatted as described below: 1. First and last names…Task 1: WordSpell English language is amalgamation of 26 standard characters. The characters are either in upper case or lower case. The words in english are made up from these characters and are categorized into Nouns, Pronouns, Verbs, Adverbs, Adjectives etc. Given a set of words in a text file, write a function WordSpell() that takes a text file as input parameter and returns a list of words that start from a specific spelling. Input data: - A text file named as Words.txt containing more than 1000 words. Output data: A python list that contains the words starting from specific spelling. Constraints: The words should only be string values. If there are any special characters in between the words, your function should omit those special characters. Function should be able to process both upper- and lower-case letters def Wordspell (file, spell): // your code goes here Example: spell "pre" print (WordSpell (file, spell)) #the function should return ['predefined', 'predestination',…Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
- Why Is It necessary for the stream Insertion (operator>) functions to return a reference ostream and Istream respectively ? Write your answer here.msleep**** For this assignment, you must name your R file msleep.R (using Rstudio) For all questions you should load tidyverse. You should not need to use any other libraries. Load tidyverse with suppressPackageStartupMessages(library(tidyverse)) The actual data set is called msleep Round all float/dbl values to two decimal places. If your rounding does not work the way you expect, convert the tibble to a dataframe by using as.data.frame() All statistics should be run with variables in the order I state E.g., “Run a regression predicting mileage from mpg, make, and type” would be: lm(mileage ~ mpg + make + type...) Before attempting to answer these, or if you lose points upon an attempt, please review all CodeGrade information provided in the CodeGrade overview submodule - if you do not you are likely to lose points.
