read a student file into an array of structs, determine grades, sort the array and print it out.

Question

Use the Student struct shown below.

Read the input file and store the data in an array of structs. The input file contains student records and one heading line.

Write code to determine the grade for each student. The grade determination is exactly as specified for this class in the syllabus. Remember to discard the lowest assignment grade.

Sort the array of student students in descending order by the total points.

Write the output file using the exact format shown below and include the two lines of headings in the output.

Required Student struct and named constants

const unsigned NumberOfStudents = 55;

const unsigned PointsPossible = 400;

const unsigned NumberOfAssignments = 10;

const unsigned NumberOfExercises = 10;

struct Student

{

   int id;

   string name;

   int exercise[NumberOfExercises];

   int assignment[NumberOfAssignments];

   int midterm;

   int final;

   int extra;

   int exerciseTotal;

   int assignmentTotal;

   int totalPoints;

   int percent;

   string grade;

};

Answer 1

If have uploaded the source code for you because it is too big for this box.

THe filename is student grades.cpp

and it is in the RESOURCES section under TOOLKIT, found

underneath the link to this post.

Notes to some issues...

(1) the sample input does not list ALL of the records in the file. As a result

the sample input and the sample output shown do not agree, which is slightly

confusing. The I/O should have been limited, as an example only, to the 7 records

displayed in the example

(2) There is NO WAY, an integer can store the values for student id as listed.

I doubt a LONG integer could do it. Therefore I changed the data type

to string.
