Test Average and Grade Write a program that asks the user to enter five test scores. The program should display a
letter grade for each score and the average test score. Write the following methods in the
program:
calcAverage:
This method should accept five test scores as arguments and return the
average of the scores.
determineGrade:
This method should accept a test score as an argument and return a
letter grade for the score, based on the following grading scale:
Score Letter Grade
90-100 A
80-89 B
70-79 C
60-69 D
Below 60 F
Expected Output:
Enter·test·grade·for·student·1:55↵ ·
Enter·test·grade·for·student·2:65↵ ·
Enter·test·grade·for·student·3:75↵ ·
Enter·test·grade·for·student·4:85↵ ·
Enter·test·grade·for·student·5:95↵ ·
The·letter·grades·are·as·follows:↵< br /> Student·1:·F↵
Student·2:·D↵
Student·3:·C↵
Student·4:·B↵
Student·5:·A↵
The·average·grade·was:·75.00↵
ISSUES: PLEASE HELP:
I can not get the student's letter grade to display correctly;
I can not get the average to calculate correctly;
Instructions states to write the METHODS in the program.
My output:
Enter test grade for student 1:50
Enter test grade for student 2:60
Enter test grade for student 3:70
Enter test grade for student 4:80
Enter test grade for student 5:90
The letter grades are as follows:
Student 0.0F
Student F
Student F
Student F
Student F
Average:0.0
