write this c program

The Inputs
Write a c program that uses overloaded functions to assess individual student grades. Each time
through the program's main loop, it takes in a string that is in one of four forms:
• a single numerical grade as a floating point number that represents the student's final mark
(ranging from 0.0 to 100.0)
• a letter grade that is one of the following: A+, A, B+, B, C+, C, D, F, I, Q, AU, DNA, I/P – again
that represents the student’s final grade
• from one to five numerical grades that are integers that represent the student's mark on each
of five assignments worth 20% each, separated by spaces (the marks range from 0 to 100).
Sample input might be :
o 80 70 65 80 60 >>> which results in a final grade of 71.00 %
o 80 90 50 >>> which results in a final grade of 44.00%
• a single character, 'X', that indicates that the user wants to exit the program
• Please note that this is not a menu-based program. That is, you are not to ask the user what
type of grade they want to enter. You must take their input and determine what type of input
they specified. This means you need to develop a function which intelligently parses their
input to determine if they have entered a single double value, a single letter grade or from 1
to 5 integers.
The string will be analyzed to determine if the student passed, failed, or had a special situation. If the
student passes or fails, display a line that gives the numerical value of the mark and an indication as
to whether the student passed or failed. A mark of 54.50% or higher is required in order to pass. Your
program’s output should look like this:
Student achieved ###.## % which is a PASS condition. or
Student achieved ###.## % which is a FAIL condition.
Important Notes:
• The two lines above will be the only allowed output from your program with the exception of
o Special Situations (as noted below)
o Any error messages that you need to output from your program
• Also note that in all input cases (the final grade, the letter grade and the assignment marks) –
the program will output the grade as a floating point number (up to 2 decimal places)
• When testing your program I will only include valid input (i.e. a floating point number, an
acceptable alpha-only input and a set of 1 to 5 integer values). Where
o an acceptable floating point number may be “60.5” or “12500.6” or “-12.76”
o an acceptable alpha-only input may be “A+”, “I/P” or “Hello”
o an acceptable set of integers may be “1 2 3”, “673 -23 70 30 20”
• This means that I will not test with data like the following. It also means that you do not have
to check for input given like this
o I will not test with data like “6A.4”, “10 20 30 40 50 60 70”, “a+”, “50 A+ 30 45.2”, …
• In no input’s case will there be any trailing spaces so your solution should not depend on
having trailing spaces
Special situations are denoted by the letter grades as follows:
Letter Grade                                      Meaning
I                                                       Incomplete
Q               Withdrawal after drop/refund date
AU                                                            Audit
DNA                                          did Not Attend
I/P                                                   In Process

If there is a special situation, then the output would show the information as follows:
Student has Special Situation : AU (Audit Condition)
For display purposes, the numerical equivalents for the letter grades are:

Letter Grade                 Numerical Equivalents
A+                                                              95
A                                                                85
B+                                                             77
B                                                               72
C+                                                             67
C                                                               62
D                                                              57
F                                                               50

What to Do
You must create three overloaded functions called assessGrade(). They will differ in their parameter
lists:
• One will take a single parameter (char *) containing a letter grade or special situation.
• One will take a single parameter (double) containing the final mark.
• One will take five integer parameters containing assignment marks (or an array of five
integers).
You will create and submit only the following files:
• a .c that contains the main loop requesting the user’s input and the call to parse
and determine the type of user input
• another .c that contains the logic for the 3 overloaded functions
• a .h that contains the prototypes for the 3 overloaded functions as well as any
other defines or constants you may need
