Hi all I am working on a school beginners project using files I/O in C++,
This program consist of two parts:
1) reading and processing a student data file, and writing the results to a student report file
2) modifying part 1 to calculate some statistics and writing them to another file.
For this assignment, you will be reading one input file and writing out two other files.
Your program will be run using the referenced student data file.
Part 1 Detail
Read in the student data file. This 50 record file consists of a (8-digit numeric) student id, 8 assignment's points, midterm points, final points and lab exercise points. You must again follow the syllabus specifications for the determination of the letter grade, this time, processing 50 student grades. Extra credit points are not applicable for this assignment. You will write the input student data and the results of the processing into a student report file that looks like the output shown below. In addition to the input student data, the report should contain the "total" of the assignment grades, the total and percent of all points achieved, and the letter grade. You may assume that the input data file does not contain any errant data.
The file looks like the one below:
The file that we need to read from is hyperlinked here
The student report output file should look like this:

Part 2 Detail
Write a summary report file that contains the average total points and average percent for all students. Also, display the number of A's, B's, C's, D's and F's for the students. Your summary output file should look something like this:
The average total points = ???
The average percent total = ??
The number of A's = ??
The number of B's = ??
The number of C's = ??
The number of D's = ??
The number of F's = ??
Additional requirements
All files must be checked for a successful open. They should also be closed when you are finished with them.
Make sure you write the student id with a leading 0, if appropriate (i.e. the 8th id).
Add headings to your output report file. They should be aligned and correctly identify the column data.
Do not use global variables, except for constants, in your solution.
For part 1 How do I duplicate the file and format it to add the headings above it and the grades at the end of each file into the new duplicated file??
Any help in this matter would be appreciated
thanks in advance.

Answer 1

Engineering is all about converting a large complex problem into many smaller, easy to solve, problems.
Here is how I would start.
1.) Open input file.
2.) Read one line from input file.
3.) Break the input string from one line into values.
4.) Close input file.
5.) Open output file.
6.) Write results to output file.
References:
1.)File I/O
2.)std::string
3.)File I/O C
Now you're pretty much there. Take it one step at a time.
