Question

**ANSWER MUST BE IN PSEUDOCODE**

Write a program that will accept an unknown number of grades in the form of numbers, calculates the GPA, and then outputs the letter grade for each with the calculated GPA.

For the input, the first number will reflect the number of grades being entered. The remaining inputs will be the actual grades in number form. Only grade values from zero to four will be accepted. Any other entered value should receive a zero as the value inserted into the array. The input and output will use the following numbers to reflect a letter grade:

A = 4
B = 3
C = 2
D = 1
F = 0
To calculate the GPA, total up the values in the grades array and divide by the number of elements in the array.

Testing Invalid Number of Grades
If the user enters a value of zero or less for the number of grades being entered, the following should output:

Example Input

-4 1 2 3 4
Example Output

The number of grades to enter must be greater than 0.
Testing Valid Grades
Example Input

4 4 3 2 1
Example Output

The following grades: A B C D
Earned a GPA of: 2.5
Testing Valid and Invalid Grades
Example Input

4 4 6 2 -1
Example Output

The following grades: A F C F
Earned a GPA of: 1.5

**ANSWER MUST BE IN PSEUDOCODE**

Answer 1

SET totalGrades to 0

SET totalPoints to 0

SET numGrades to INPUT from user

SET grades[numGrades] to empty array

IF numGrades <= 0 THEN

OUTPUT "The number of grades to enter must be greater than 0."

ELSE

FOR i from 0 to numGrades-1 DO

SET grade to INPUT from user

IF grade < 0 OR grade > 4 THEN

SET grade to 0

END IF

SET grades[i] to grade

SET totalPoints to totalPoints + grade

END FOR

Step-by-step explanation:

FOR i from 0 to numGrades-1 DO

SET letterGrade to empty string

IF grades[i] == 4 THEN

SET letterGrade to "A"

ELSE IF grades[i] == 3 THEN

SET letterGrade to "B"

ELSE IF grades[i] == 2 THEN

SET letterGrade to "C"

ELSE IF grades[i] == 1 THEN

SET letterGrade to "D"

ELSE

SET letterGrade to "F"

END IF

OUTPUT "The following grades: " + letterGrade + " "

END FOR

SET gpa to totalPoints / numGrades

OUTPUT "Earned a GPA of: " + gpa

END IF
