Chapter 5, Problem 24PC
Using Files—Total and Average Rainfall
Write a
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 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.

In a text file, I have two numbers each line. The numbers are the employee ID and the number of hours the employee work. My goal of this program is to read the both employee ID and the number of hours the employee work and print it out in the main program. If the list of employee id is not in order, sort it in order and still print it out in the main program. Additionally, after printing them out, print out the total number of employees and the total number of hours all the employee work. Write this in java
For example
File.txt
EmployeeID Number of Hours Work
3 12
2 20
1 40
5 20
7 9
In the main program print:
EmployeeID Number of Hours Work
1 40
2 20
3 12
5 20
7 9
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. I recommend calculating a student's exam average and letter grade as you read the file, although this is not a…
Here are the two programs which you may choose from to do this program:
1. 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.

- PYTHON CODINGarrow_forwardI am confused on how to go about writing this python program.arrow_forwardA Company wants to produce a product orders report from its product orders file. Each record on the file contains the product number of the item ordered, the product description, the number of units ordered, the retail price per unit, the freight charges per unit, and the packaging costs per unit. Your algorithm is to read the product orders file, calculate the total amount due for each product ordered and print these details on the product orders report. The amount due for each product is calculated as the product of the number of units ordered and the retail price of the unit. A discount of 10% is allowed on the amount due for all orders over GHC100.00. The freight charges and packaging costs per unit must be added to this resulting value to determine the total amount due. Answer should be in pseudo codearrow_forward
- The manager of a football stadium wants you to write a program that calculates the total ticket sales after each game. 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.

Each line contains the Last Name, First Name and 8 marks separated by spaces of a single student. For each student in the file, adjust the file to include the average of their top 6 marks, rounded to 1 decimal place, at the end of the line. For example, in the file, the line may say: Mars, Bruno 82 82 85 94 65 79 81 90 Afterwards, it should be updated to say: Mars, Bruno 82 82 85 94 65 79 81 90 Top6Avg: 85.7 Your program must define a function to determine the average of the top 6 marks.

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.
