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:
У — Ул
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, yl, x2, y2,
where x1, yl are the coordinates of the first point and x2, y2 are the coordinates of the second point.

1. Write a java program that asks the user for a positive nonzero integer value. The
program should use a loop to get the sum of all the integers from 1 up to the number
entered. For example, if the user enters 50, the loop will find the sum of 1, 2, 3, 4, .

- Java Write an application that allows a user to enter the names and birthdates of up to 10 friends. Continue to prompt the user for names and birthdates until the user enters the sentinel value ZZZ for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birthdate or "Sorry, no entry for name" if the name has not been previously entered. The loop continues until the user enters ZZZ for a name.arrow_forwardCase - I: Playing with Digits Write a program which reads input integers from input file which consists a series of numbers where each integer contains only of the digits from 0 to 9.

Using Files - Student Line Up Modify the Student Line Up program described in Programming Challenge 14 which states: "A teacher has asked all of her students to line up according to their first name. For example, in one class Amy will at the front of the line, and Yolanda will be at the end. Write a program that prompts the user to enter the number of students in the class, then loops to read that many names. Once all of the names have been read, it reports which student would be at the front of the line and which one would be at the end of the line. You may assume that no two students have the same name. You are now to do this program reading names from a file. Names should be read in until there is no more data to be read. I am providing for you a file named LineUp.txt for you to use in writing this program. I suggest that you write it first without the file and then modify to add the file.arrow_forward
- Your program should use a loop to read data from a text file which contains students' names and 3 exam scores. The program should calculate the exam average for each student, determine the appropriate letter grade for that exam average, and print the name, average, and letter grade. After printing all this, you need to print the count of the total number of A's, B's, C's, D's, and F's for the whole class. The text file you need to use can be accessed using this link: scores.txt. Copy this file to the folder where your program will reside. The text file contains a list of 30 records, and each record contains a name and that person's 3 test scores. Each field is separated by a tab character. The first 2 records looks like this: Davis 88 92 84Wilson 98 80 73 and so on. Your program will need to open this file and read each line until the end of file.

The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…arrow_forwardWrite a java code that does the following: Opens a file named NumberList.txt, uses a loop to write the numbers 1 through 100 to the file, and then closes the file.

Opens the NumberList.txt file and reads all of the numbers from the file, calculate the sum of these numbers and displays their total.

- A Personal Fitness Tracker is a wearable device that tracks your physical activity, calories burned, heart rate, sleeping patterns, and so on. One common physical activity that most of these devices track is the number of steps you take each day. The steps.txt file contains the number of steps a person has taken each day for a year. There are 365 lines in the file, and each line contains the number of steps taken during a day. (The first line is the number of steps taken on January 1st, the second line is the number of steps taken on January 2nd, and so forth.) Write a program that reads the file, then displays the average number of steps taken for each month. (The data is from a year that was not a leap year, so February has 28 days.) You don't need to see the file , Just write a code using the "file" like this def main(): with open("steps.txt", "r") as file:arrow_forwardOBJECT ORIENTED PROGRAMMING LESSON LABORATORY EXERCISE-1 Problem: Write a program that takes position and current salary value from the user and calculate the new salary and shows it on the console according to the following table.

Then load it into UZEM under the provided link.arrow_forwardThe 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_forward
