Part A :

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 40.0 90.0 100.0 83.0

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

LastName FirstName SSN Test1 Test2 Test3 Test4 Average FinalGrade

i.e.

Alfalfa Aloysius 123-45-6789 40.0 90.0 100.0 83.0 78.25 .0 C+

The program must be written to use the enum letterGrade :

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

Use the following function prototype for deriving letter grade :

letterGrade deriveGrade(double average) ;

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

The function deriveGrade should derive the letterGrade 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(letterGrade grade) ; //This function converts a letterGrade type to a string type.

Requirement :

• The namespace gradeOpt definition should contain the following members
  1. the enum letterGrade definition,
  2. deriveGrade(..) function prototype and
  3. convertToText() function prototype
• Add the namespace gradeOpt to the grade.h header file and the namespace member function definitions to the file grade.cpp file.C++
