Assignment Grade Calculation: A certain class has no more than 100 students and has 6
Assignments each worth 20 points throughout the semester. Write a program that will read the
names and scores of the students from a file. The name of the first student will be on the first
line and their 6 scores separated by spaces on the next line (the two files your program will be
tested against are given on Blackboard). This will repeat for all students in the class. First ask
the user for the file name and open it for reading. Be sure that it opens properly. For every
student in the class read in the name of the student into an array and their scores on the 6
Assignments into a 2D array. It is possible to earn half a point grades (for example 18.5), somake the type of the array for the scores appropriate. The index of the name and row of the
grades should link the two arrays as parallel.
After the scores are read in, display a table that includes the student names, their scores on the
assignments and their average after dropping the lowest grade.
• Hint: combine the min and sum algorithms. When looking for the min if it's updated add
the old min to the sum before updating; otherwise, add the current element to the sum).
• Hint: Use an array to hold each student's average score, since we will need them later to
calculate their average.
Also below every column, the following should be displayed (see sample output below):
• average for each assignment,
• Bonus (2pts): the standard deviation for each assignment
◦ The standard deviation can be found by modifying the following formula
▪ std deviation = sqrt ( sum ((score[i][j] – average_score[j]) ^ 2) / number of scores)
◦ Hint: Use an array to hold the average score on each assignment. Then for each
column use nested loops to sum up all the scores in that column minus the average in
the column squared. After the inner loop, divide that answer by the the number of
scores and then finally take the square root.
• the number of students who earned an “A” (a score greater than or equal to 18) on the
assignment
For full credit:
• Use parallel arrays for the name and scores
• Use a partially filled array for the names
• Use a 2D array for the scores
• Use constants for the max number of students (100) and the number of
assignments (6)
• Display all numbers to one decimal point
• Follow standard naming procedure for your variables (camelCase or under_score
for variables and ALL_CAPS for constants) and use appropriate types (e.g. you
may read the phone number as a string). Give the variables descriptive names.
• Use spaces and comments to separate and describe the logical parts of your
program so that it is easy to read
• Indent code inside blocks, including the main function and any if, switch statements, or
loops
