Counting the character occurrences in a file For this task you are asked to write a program that will open a file called “story.txt" and count the number of occurrences of each letter from the alphabet in this file. At the end your program will output the following report: Number of occurrences for the alphabets: a was used – times. b was used – times. c was used – times. .and so, on Assume the file contains only lower-case letters and for simplicity just a single paragraph. Your program should keep a counter associated with each letter of the alphabet (26 counters) [Hint: Use array] Your program should also print a histogram of characters count by adding a new function print Histogram (int counters []). This function receives the counters from the previous task and instead of printing the number of times each character was used, prints a histogram of the counters. An example histogram for three letters is shown below) [Hint: Use the extended asci character 254]: | C:\WINDOWS\system32\cmd.exe E Press any key to continue

Create a text file of names, (3 names per line, 5 lines in total) followed by an age for each name. Go through the file and sum the ages. Create an output file with each persons name followed by age and then a line at the end of the output file that says “sum of all ages is: x”. Simple Java programming. Should include things like bufferedReader, fileReader, printWriter, fileWriter, file close, try-with-resources, Scanner, catch/try, etc. Include Java file and txt file. Thank you.
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.

Write a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). The following shows part of a typical data file: Smith 27 83.7 Jones 21 28.35 Walker 96 182.4 Doe 60 150 The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students. The file Warning.java contains a skeleton of the…

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…
The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
This is Python Program 5: Improve the file copy program from Lab 9 so that it will make sure the user enters a file that exists. If a file doesn’t exist, the open function will raise the FileNotFoundError. You do not need to check if the destination exists since a file doesn’t need to exist to write it. Instead of copying the content of the source as exact, it only copies non-empty lines and it also prepend each line with a line number. A line is empty if the length of the line stripped of white space from both end is 0. The code segment below shows how to strip white space and getting the length of the string. If the length of the line is zero, the line is a blank line. line1 = " " line2 = " aa " print(len(line1.strip())) # 0 print(len(line2.strip())) # 2 In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that “add-copy.py” contains only non-blank lines from “add.py” and each line in “add-copy.py” is labelled with a line number. Sample run:…
