Homework SourseThe Palmertown Elementary School has 30 classrooms The child
The Palmertown Elementary School has 30 classrooms. The children in the school donate used books to sell at an annual fundraising book fair. Write a program in pseudocode that accepts each teacher’s name and the number of books donated by that teacher’s classroom. Display the names of the four teachers whose classrooms donated the most books.
b. Modify the book donation program so that, besides the teacher’s name and number of books donated, the program also accepts the number of students in each classroom. Display the names of the teachers whose classrooms had the four highest ratios of book donations per pupil. and calculate all of the ratios of book donations per student first in another parallel array and then work on finding the four highest of those ratios.
Here what I have so far, please correct me if i have anything wrong. Thanks

Solution
Answer:
I have looked into our code; your code needs some modification. So I modified your code.
Modified code:
start
Declarations
num SIZE = 30
num DISPLAY = 4
string names[SIZE]
num numBooks
num numStudents
num ratios[SIZE]
num x
num y
num tempRatio
string tempName
num comparisons
x = 0
while x < SIZE
output “Enter a teacher’s name”
input name[x]
output “Enter the number of books donated”
input numBooks
output “Enter the number of students”
input numStudents
ratios[x] = numBooks/numStudents
x = x + 1
endwhile
comparisons = SIZE - 1
x = 0
y = 0
while x < comparisons
y=0
while y < comparisons
if ratios[y] < ratios[y + 1] then
tempRatio = ratios[y+1]
ratios[y+1] = ratios[y]
ratios[y] = tempRatio
tempName = names[y+1]
names[y+1] = names[y]
names[y] = tempName
endif
y = y+1
endwhile
x = x+1
endwhile
x = 0
while x < DISPLAY
output names[x]
x = x + 1
endwhile
stop
