- 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…arrow_forwardPYTHON: Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row…arrow_forwardGiven a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate arrays, and outputs the available food items in the following format: name (category) -- description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character. Ex: If the input of the program is: food.txt and the contents of food.txt are: Sandwiches Ham sandwich Classic ham sandwich Available Sandwiches Chicken salad sandwich Chicken salad sandwich Not available Sandwiches Cheeseburger Classic cheeseburger Not available Salads Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Drinks Water…arrow_forward

There are four types of tickets—box, sideline, premium, and general admission. After each game, data is stored in a file in the following form: ticketPrice numberOfTicketsSold … Sample data are shown below: 250.75 5750 100.50 28000 50.25 35750 25.00 18750 The first value indicates that the ticket price is Php 250.75 and that 5750 tickets were sold at that price. Output the total number of tickets sold and the total sale amount using c++ compiler. Format your output with two decimal places.arrow_forward
- The program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas). If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show. I need this answer in C language. Please explain nicely. Thanks.arrow_forwardJava Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…arrow_forwardPython - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next. Sample Run birthdates.csv Draven Brock, 01/21/1952 Easton Mclean, 09/02/1954 Destiny Pacheco, 10/10/1958 Ariella Wood, 12/20/1961 Keely Sanders, 08/03/1985 Bryan Sloan,04/06/1986 Shannon Brewer, 05/11/1986 Julianne Farrell,01/29/2000 Makhi Weeks, 03/20/2000 Lucian Fields, 08/02/2018 Function Call nextBirthdate("birthdates.csv", "01/01/2022") Output…arrow_forward

Each line contains a certain number of blood glucose readings followed by the patient id. Your program should then display for each patient, their id number, the number of readings, the average value of the readings followed by the patient status (Normal range: 90–120 mg/dl, Low range: less than 90 mg/dl, High otherwise). Your program should consider the following erroneous cases and display appropriate message as shown in the sample output below: • The file does not open/exist • The readings are invalid (non-integer values or negative) or missing, in which case a ValueError exception should be raised and the processing should continue. Enter input filename: patients.txt Patient Id #Readings Average Status ========== ========= ======= ====== 120 150 150 P1111 P1111 3 140 High 100 90 90 100 P2222 P2222 4 95 Normal…arrow_forward
