Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the students name (lastName, firstName middleName) and average as follows:

Doe, John K.

93.2

Andrews, Susan S.

84.7

Monroe, Marylin

75.1

Gaston, Arthur C.

62.8

Generate the output in the following format :

Doe, John K. 93.2 A

Andrews, Susan S. 84.7 B

Monroe, Marylin 75.1 C

Gaston, Arthur C. 62.8 D

The program must be written to use the enum letter_grade :

enum letter_grade {A,B,C,D,F } ;

and define two namespace (tenPoint and sevenPoint) for the function :

letter_grade deriveGrade(double average) ;

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

The first namespace tenPoint should derive the letter grade based on a ten point grading scale.

and the second namespace sevenPoint should derive the letter grade based on a seven point grading scale.

	10 Point	7 Point
A	>= 90	>= 93
B	>= 80	>= 85
C	>= 70	>= 77
D	>= 60	>= 70
F	< 60	< 70

NOTES :

use ignore() function with ifstream objects whenever you want to ignore the newline character.

For example :

ifstream transferSchoolFile ;

transferSchoolFile.open("student_status.txt", ios::in);

while( !transferSchoolFile.eof())

{

getline(transferSchoolFile, name) ;

transferSchoolFile >> average;

transferSchoolFile.ignore(); //Used here to ignore the newline character.

.

}

You have the option of placing the namespace definitions inside a separate header file (i.e. scale.h).

You can write this as two programs (each with a different namespace) OR a single program where the user is prompted to select the point scale (1. tenPoint or 2. sevenPoint).
