- 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)arrow_forwardJava languagearrow_forwardWrite a program that produces a bar chart showing the population growth of Prairieville, a small town in the Midwest, at 20 year intervals during the past 100 years. The program should read in the population figures (rounded to the nearest 1000 people) for 1910, 1930, 1950, 1970, 1990, and 2010 from a file. For each year it should display the date and a bar consisting of one asterisk for each 1000 people.arrow_forward
- Python - 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.

- 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…arrow_forwardBinus’s Used Cars, Inc. employs several salespeople. Mr. Robert, the owner of the company, has provided a file that contains sales records for each salesperson for the past month. Each record in the file contains the following two fields: The salesperson’s ID number, as an integer The amount of a sale, as a real number The records are already sorted by salesperson ID. Brewster wants you to design a program that prints a sales report. The report should show each salesperson’s sales and the total sales for that salesperson. The report should also show the total sales for all salespeople for the month. Here is an example of how the sales report should appear:arrow_forwardPlease answer and write algorithmarrow_forward
- Write a program that opens a file me.txt and write your first name followed by a space followed by your last name, then your major on the second line. If the file does not exist, create it. If the file exists, have the file's contents be erased before writing your name. Be sure to close the file after.

OPTION 1: The user chooses to lookup a name based on ID number: Use a try/except and ask the user to enter an integer. If they don't enter an integer, print an error message. If they do enter an integer, call a function named lookup_employee which takes the id as a parameter. If an employee with the given id number is found, return the name. Otherwise, return the string “Employee not found” Back in main, print the return result. OPTION 2: The user chooses to lookup an ID based on name: Ask the user to enter the first and last name (don't ask for the middle name). Call a function named…arrow_forwardUsing pythonarrow_forward
