Write a program that asks any number of students to enter their final grade and enables you to store these grades into a grades.txt plain text file. Then it reads the grades from the grades.txt file, and displays the individual grades and their count and average.
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.

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.

There are approximately455,052,511 such prime numbers. Your program should meet the followingrequirements:■■ Your program should store the prime numbers in a binary data file, namedPrimeNumbers.dat. When a new prime number is found, the number isappended to the file.■■ To find whether a new number is prime, your program should load the primenumbers from the file to an array of the long type of size 10000. If nonumber in the array is a divisor for the new number, continue to read thenext 10000 prime numbers from the data file, until a divisor is found or allnumbers in the file are read. If no divisor is found, the new number is prime.■■ Since this program takes a long time to finish, you should run it as a batchjob from a UNIX machine. If the machine is shut down and rebooted, yourprogram should resume by using the prime numbers stored in the binary datafile rather than start over from scratch.arrow_forward

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.

Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. Use the numbers.txt file to test your program. (Hint: Open the file and read every string stored in it. Use a variable to keep a count of the number of lines that are read from the file.) Comment your source code and describe your code to someone who may be viewing it for the first time.

The program should take in the number of pints donated during the drive, up to twenty-four-hour drive period, from an input file, bloodDrive.txt. The average pints, highest pints, and lowest pints donated during that period should be calculated and written to a file called bloodResults.txt. We will only run the program once so a yes/no loop is not needed. Step 1: Note that the getHigh, getLow, and getAverage functions do not change. We need to modify modules getPints and displayInfo to meet the new requirements. Complete the pseudocode below for the two modules according to instructions: In the getPints Module (notice there is a new pass-by-reference parameter count) Declare an input file with the name bloodInFile.

The output should be stored in a file called testavg.txt. test.txt: A file containing the student names and the five test scores for every student.
