Assignment 4

Write a program that calculates the semester grades of students. The program first reads the number of students, and then reads 6 scores for each student. Each score is an integer, and ranges between 0 and 10. Assume that there are at most 10 students. The program outputs the semester grades of students and the number of the most difficult quiz.

• The semester grade of a student is the average of the 4 highest scores. 

• The number of quiz begins from 1. That is, the quiz numbers are: 1, 2, 3, 4, 5, 6. The most difficult quiz is the one that produces the smallest sum of student scores.

  • If there are two quizzes of the same difficulty, then report the one with the smaller quiz number.

Program Input

Enter the number of students: 3

Enter the scores for each student:

 4  1 10  6  1 10 

 9  2  6  3  8  9 

 5  0  3  1  7  3 

Program Output

Table of Semester Grades: 

         Stud1  Stud2  Stud3

Grades:    7.5    8.0    4.5

The number 2 quiz is the most difficult one.

• Your solution should be based on the code template .

• Your program must conform the following requirements: 

  • The outputs of your program should behave as in the above example.

  • You only need to add your code to the function definitions of computeSemesterGrades() and displayHardQuiz()

    • Add your code according to the comments in the function definition.

  • Do not modify readStudentGrades() and displaySemesterGrades()

  • Do not modify main() unless you know what you are doing.

  • Do not modify any cin or cout statements, and do not add any cout statements. Otherwise, your program might not be evaluated properly.

• More input-output samples.

• Hint:

  • You can use sort(array, array+5) to sort an array with size 5.
