Write a program that asks a user to input a file name and then reads the file and produces output. The file has the following format. Kim 8 10 6 4 Ivan 9 2 7 8 Sue 7 8 9 10 Kevin 4 6 57 The output should be each name followed by the average score. For example: Kim: 7.00 Ivan: 6.00 Sue: 8.50 Kevin: 5.55

QI: Write a program to calculate the average of four integer score, and find the grade for 7 students. The program should do the following: 1. Read the first, second name and the four score of the 7 student from the file (E:lexam.txt), 2. Calculate the average and find the grade of the average by using the if and if else. 3. Save the first, second name, average and the grade for each student in file (E:grade.txt). (10 columns for the first and second name. 4 columns, precision 2, for the average and grade)

Write a program to draw a quiz score histogram. Your program shouldread data from a file. Each line of the file contains a number in the range0-10. Your program must count the number of occurrences of each scoreand then draw a vertical bar chart with a bar for each possible score (0-10) with a height corresponding to the count of that score. For example,if 15 students got an 8, then the height of the bar for 8 should be 15.Hint: Use a list that stores the count for each possible score. An examplehistogram is shown below: o o D D0 1 2 3 4 5 6 7 8 9 10

For this assignment, you will write a Python program that uses a file named scores.txt to store sets of bowling scores for different dates. scores.txt should store the data so that each line has a month, day, and the scores the user earned on that date. As an example, scores.txt might look something like this: January 15 200 300 126 200 250April 20 125 100 May 17 300 100 215 The very first time your program starts, scores.txt should not exist (i.e. create it with Python code the first time the program runs). In your main function, continuously give the user the following five options:  Quit the program. View all Scores.  If the user selects this option, call a function named view_scores. This function should print the scores in a nicely formatted manner. For example: "On January 15, you scored 200, 300, and 126", etc.. Add a Score. If the user selects this option, call a function named add_score. This function should ask the user for a month, day, and as many scores as they want to…

Java 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…

Given a text file food.txt containing the availability of food items. Write a program that reads the information from the text file and outputs the available food items. Add comments to better understand it txt.file content ========== Sandwiches Ham sandwich Classic ham sandwich Available Sandwiches Chicken salad sandwich Chicken salad sandwich Available Sandwiches Cheeseburger Classic cheeseburger Not available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Beverages Water 16oz bottled water Available Vegetarian Avocado sandwich Sliced avocado with fruity spread Not available Mexican food Beef tacos Ground beef in freshly made tortillas Available Mexican food Chicken tacos Grilled chicken breast in freshly made tortillas Not available Beverages Coca-Cola 16oz Coca-Cola Available

Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles   The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams   Use arrays to solve the problem.

Write a program that reads in from a file a starting month name, an ending month name, and then the monthly rainfall for each month during that period. As it does this, it should sum the rainfall amounts and then report the total rainfall and average rainfall for the period. For example, the output might look like this: During the months of March-June, the total rainfall was 7.32 inches and the average monthly rainfall was 1.83 inches. Data for the program can be found in the rainfall.txt file located in the Chapter 5 º programs folder on the book's companion website. Hint: After reading in the month names, you will need to read in rain amounts until the EOF is reached and count how many pieces of rain data you read in.

Problem A straight line can be defined by a pair of points p1(x1, yı) and p2(x2, y2). The slope m of a line is defined as follow: У2 — У1 m = X2 - X1 Your program reads the points from a text file called 'points.txt’ which contains the coordinates of unknown number of pairs of points as shown in Figure 1. Each line contains four values x1, y1, x2, y2, where x1, yl are the coordinates of the first point and x2, y2 are the coordinates of the second point. 10 -2 7.5 -3.2 4 15.5 -4.6 21 -2 Зр 12.5 6. 2 5 -3 -6 10 3 10 15 Figure 1. Input file contains unknown number of point pairs Use Spider, to create the following files: (i) The input file 'points.txt' shown in Figure 1. Your Python program that reads from the input file 'points.txt', the coordinates of unknown number of pairs of points, computes the corresponding slopes then prints the results on the screen as shown in Figure 2.
