Program Description:

Write a program to generate a report based on input received from a text file. Suppose the input text file student_grades.txt contains the students Last name , First name, SSN, Test1, Test2, Test3, and Test4.

i.e.

Alfalfa Aloysius 123-45-6789 90.0 100.0 83.0 49.0

Generate the output Report File student_final.txt in the following format :

LastName FirstName SSN Test1 Test2 Test3 Test4 FinalLetterGrade

i.e.

Alfalfa Aloysius 123-45-6789 90.0 100.0 83.0 49.0 C+

Last name First name SSN Test1 Test2 Test3 Test4 Final Grade

The program must be written to use the enum letter_grade :

enum letter_grade {A, A_PLUS, A_MINUS, B,B_PLUS, B_MINUS, C, C_PLUS, C_MINUS,D,D_PLUS,D_MINUS,F } ;

Use the following function prototype for deriving letter grade :

letter_grade deriveGrade(double average) ;

The average is calculated as follows : (test1 + test2 + test3 + test4)/4.0

The function deriveGrade should derive the letter_grade of the student based on the following grading scale.

Letter Grade	Percentage
A+	97%+
A	93%-96%
A-	90%-92%
B+	87%-89%
B	83%-86%
B-	80%-82%
C+	77%-79%
C	73%-76%
C-	70%-72%
D+	67%-69%
D	63%-66%
D-	60%-62%
F	0%-59%

Also provide the following function :

string convertToText(letter_grade grade) ; //This function converts a letter_grade type to a string type.

NOTES :

• Place the namespace in a header file (i.e. grade.h)
• and place the enum type, convertToText(..) and deriveGrade(..) functions in the namespace stdGrade

This is the Text File provided.
