Chapter 6, Problem 3PP

Enhance the program you wrote for Programming Project 2 in all of the

following ways.

a. The list of quiz scores on each line will contain ten or fewer quiz scores. (If there are fewer than ten quiz scores, that means the student missed one or more quizzes.) The average score is still the sum of the quiz scores divided by 10. This amounts to giving the student a 0 for any missed quiz.

b. The output file will contain a line (or lines) at the beginning of the file explaining the output. Use formatting instructions to make the layout neat and easy to read.

c. After placing the desired output in an output file, your program will close all files and then copy the contents of the “output” file to the “input” file so that the net effect is to change the contents of the input file.

Use at least two functions that have file streams as all or some of their arguments. If this is being done as a class assignment, obtain the file names from your instructor.

Blurred answer
Students have asked these similar questions
The program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas).   If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show.   I need this answer in C language. Please explain nicely. Thanks.
You are required to implement a program which will read in a text file (.txt) containing words which are arranged in sentences. Your program should first ask the user for the name of the file and then count the number of individual words and characters (including numbers and punctuation) in the file. The word and character count result should be printed on the screen. Furthermore, your program should count the number of individual words starting with the letter 'A', 'B', 'C' and so on to 'Z'. Again, these statistics should be printed on the screen. Your program should display the letter that appears at the start of most words. The program must be written in C. You should illustrate the operation of your program by generating a text file containing 3 sentences from a lead news story on the day of testing.
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.
