Need Help in Arrays
Write a program that demonstrates various gradebook utilities. The program should first create a
two-dimensional array initialized with short values, where each value is a grade in the range 0 through 100.
Each row in this array should be treated as all the grades for a particular student, and each column in this array
should be treated as all the grades for a particular assignment. Then the program should demonstrate using
that array with each of the following functions:
● printGradeScores: This function should accept a two-dimensional array as its argument and print the
contents of the array to the screen as numeric grades in a report formatted like this:
○ Student #1: 74 59 91 11 94
○ Student #2: 48 67 4 68 92
○ Student #3: 92 71 83 80 100
● printGradeLetters: This function should accept a two-dimensional array as its argument and print the
contents of the array to the screen as letter grades in a report formatted like this:
○ Student #1: C F A F A
○ Student #2: F D F D A
○ Student #3: A C B B A
where A=90-100, B=80-89, C=70-79, D=60-69, F=0-59
● getStudentTotalScores: This function should accept a two-dimensional array and a student
number(valid values start at 1) as its arguments and return the sum of all this student's scores.
● getStudentAverageScore: This function should accept a two-dimensional array and a student
number(valid values start at 1) as its arguments and return the average assignment score for this
student.
● getStudentAverageLetter: This function should accept a two-dimensional array and a student
number(valid values start at 1) as its arguments and return the average assignment letter grade for this
student, using the letter grade scale above(see printGradeLetters).
● getAssignmentTotalScores: This function should accept a two-dimensional array and an assignment
number(valid values start at 1) as its arguments and return the sum of all scores earned for the
assignment.
● getAssignmentAverageScore: This function should accept a two-dimensional array and an
assignment number(valid values start at 1) as its arguments and return the average of all scores
earned for the assignment.
● getAssignmentMaxScore: This function should accept a two-dimensional array and an assignment
number(valid values start at 1) as its arguments and return the maximum score earned for the
assignment.
● getAssignmentMinScore: This function should accept a two-dimensional array and an assignment
number(valid values start at 1) as its arguments and return the minimum score earned for the
assignment.
