Write a program that reads student data from a file, compute their GPA and writes the results to a different file. 1. The user should have the option to either enter their text file that contains the student grades or use the provided text file that contains theinformation.

Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line.*Note that the contents of the file AcctNumsIn.txt will change when the test is run to test the program against different input.

Write a program, and store it in a file called Travel Expenses.xlsm, that does the following: (a) It asks for a person’s first name and stores it in firstName; (b) it asks for a person’s last name and stores it in lastName; (c) it asks for the number of miles the person traveled on a recent trip and stores it in nMiles; (d) it asks for the average miles per gallon the person got on the trip and stores it in milesPer- Gallon; (e) it asks for the average price per gallon paid for gas on the trip and stores it in avgPrice; (f) it calculates the cost of the trip and stores it in tripCost; and (g) it displays a message such as "Bob Jones traveled 800 miles, got 31.3 miles per gallon on average, paid $3.49 per gallon on average, and paid a total of $89.20 for gas." Make sure there is an Option Explicit line at the top of the module and that you declare all of your variables appropriately.
Write a program in a single file that: Main: Creates 10 random doubles, all between 1 and 11, Calls a method that writes 10 random doubles to a text file, one number per line.

The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:TFFTFFTTTTFFTFTFTFTTEvery other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:ABC54301 TFTFTFTT TFTFTFFTTFTindicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9. The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score, followed by the test grade. Assume the following grade scale:90%–100%, A; 80%–89.99%, B; 70%–79.99%, C; 60%–69.99%, D; and…

Write a program that receives a filename as user input. The file is structured as multiple lines containing numbers separated by a single space.For example, this would be an acceptable file: 1 2 3 4 5 6 7 2 Your program should open this file and: print all its contents; write the median of all numbers to a new file called result.txt. IMPORTANT NOTES: the median is the element in the middle when you sort the values; the median of values (2, 1, 3) is 2, because when you sort them, you get 1, 2, 3, and 2 is the value in the middle. you can assume there will be no empty lines; there might be any arbitrary number lines in the file; there might be any arbitrary number of elements in a single line; you can assume there will always be an odd number of elements. Example 1: If input is: file1.txt and the contents of file1.txt are: 1 2 2 you should first print the content, and then write 2 to result.txt. Example 2: If input is: file2.txt and the contents of file2.txt are: 1 2 3 4 5 1 7 you…
WRITE A PROGRAM In this problem you will read a file with one row that that has the format #'s,_.._#,_.._#, ..........#, Here # consists of a string of symbols that can be interpreted as a number. _..._ means one blank or more than one blank. "," of course means one comma. After reading this file you should convert all the number strings ( EX: 1,2,3,4) to actual Double data type numbers. Here are some very helpful commands to use: Split, Trim, CDbl. I need a windows application that can split the contents of text file, trim it, and then convert to a double number. Finally, you should find the magnitude of the vector represented by the numbers in the file. Remember magnitude of a vector x==||x||=sqrt(x1^2+x2^2+...+xn^2) . The answer should be output in a text box and there should be a button that say " READ FILE" to read the file and a button that say " CALCULATE MAGNITUDE" to calculate the magnitude.
Write a program that opens a text file called quiz.txt for reading. This file contains a single linewith a student’s first name then one space, then the student’s last name, then one space, then somenumber of quiz scores that, if they exists, are separated by one space. The student will have betweenzero and ten scores (inclusive), and each score is an integer between 0 and 100 (inclusive). The filemay or may not end with a new line character. Your program will read the data from this file andwrite its output to a second file. The data in the output file (named average.txt) will contain thestudent’s quiz scores followed by the average of the student’s quiz scores.The output file must be formatted as described below.1. Each quiz score should be listed in a right-justified column that is 4 characters wide. Notethat if a student has fewer than 10 scores (they have missed one or more of the quizzes), yourprogram will need to display the missing score(s) using 0 for each one.2. The average…
Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. 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 .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • 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 • Output the first names, last names, exam scores, and letter…
