C$++$ program that utilizes user interactions, loops, an input file, and

functions

Specifics: For this assignment you are required to write a modular

C$++$ program that processes student grades. The program requires

you to use all of the programming structure we've discussed so far

in class $($e$.$g$.$ simple sequence, decisions, and looping$)$ and

incorporate functions that perform specific actions for your

program.

Background: To begin with, your program needs to use a data file

that I created that contains student data. Each line of the file has

the following data in order:

$$ First name

$$ Last name

$$ Test One

$$ Test Two

$$ Assignment $1$

$$ Assignment $2$

$$ Assignment $3$

$$ Assignment $4$

$$ a number representing the number of classes they attended out of $30$

An example of this: Don Southwell $87932123252027$

The teacher's class policy is that students are required to take two tests and complete $4$

assignments. Of the four assignments, the lowest score can be dropped. The remaining three

assignments together bear as much weight on the final grade as a single test $($hint: after

dropping the lowest assignment, add the remaining assignments and then average with tests$).$

You will also need to determine if the student has met minimum requirements for passing the

class and their final grade. Minimum requirements involve attendance and minimum grade

performance $-$ if the student has attended less than $20$ classes, it is an automatic failure. If a

student's grade average is lower than $60\%,$ the student is considered to have failed also, no

matter how many classes they attended.

The teacher wants to see $($on the monitor$)$ for each student, the following:

$$ First name and Last Name

$$ Test Scores and Assignment Scores

$$ Final average

$$ Letter grade corresponding to the final average $($use normal grading scale$)$

$$ A message letting him know if they pass or fail or fail due to attendance.

Format the output so the information is displayed in an attractive and readable manner.

Your program should do the following:

$$ Initialize the environment.

$$ Open the data file $($file can be found here$).$ Save this file in the same folder where you

store your program.

$$ Process one record at a time using a loop.

$$ Perform proper cleanup after all the records are processed.

Other Requirements:

$1.$ The program must handle a completely variable number of students. My grades.txt file

could have one student or it could have $40$ or somewhere in between. I may test your program

with a different number of students than you use for testing.

$2.$ The program must have four functions other than main. Please include the following

functions:

a$)$ An output function that creates the report header.

b$)$ A function that calculates the student$$s average.

c$)$ A function that determines whether the students pass or fail.

d$)$ A function that displays the total number of students processed. A count of the number of

students that have passed a count of those who failed.

Only one function may be a void function or have an empty parameter list. In other words, you

need functions that are passing things in and out. Try to use reference parameter$($s$)$ if you

need to return more than one value from a function.

Absolutely no global variables may be used!
