Question:
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 student’s 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 49.0 Generate the output Report File student_final.txt in the following format : LastName FirstName SSN Test1 Test2 Test3 Test4 FinalGrade i.e. Alfalfa Aloysius 123-45-6789 40.0 90.0 100.0 83.0 49.0 D- 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 | GPA |
| A+ | 97%+ | 4.33/4.00 or 4.00/4.00 |
| A | 93%-96% | 4.00/4.00 |
| A- | 90%-92% | 3.67/4.00 |
| B+ | 87%-89% | 3.33/4.00 |
| B | 83%-86% | 3.00/4.00 |
| B- | 80%-82% | 2.67/4.00 |
| C+ | 77%-79% | 2.33/4.00 |
| C | 73%-76% | 2.00/4.00 |
| C- | 70%-72% | 1.67/4.00 |
| D+ | 67%-69% | 1.33/4.00 |
| D | 63%-66% | 1.00/4.00 |
| D- | 60%-62% | .67/4.00 |
| F | 0%-59% | 0.00/4.00 |
Also provide the following function :
string convertToText(letter_grade grade) ; //This function converts a letter_grade type to a string type.
