Question

Write an application that allows a user to enter any number of student quiz scores, as integers, until the user enters 99. If the score entered is less than 0 or more than 10, display Score must be between 10 and 0 and do not use the score. After all the scores have been entered, display the number of valid scores entered, the highest score, the lowest score, and the arithmetic average.

Answer 1

python:

Code:

#count to store the number of valid inputs
count=0
#highdcore
highscore=-1
#low score
lowscore=100
#variable to store sum
s=0
#an infinite loop which only breaks when 99 is entered
while(True):
   #taking input
   num=int(input("Enter Quiz score "))
   #checking if it is 99
   if(num == 99):
       break
   #if it is not between 0 and 10
   if(num<0 or num>10):
       print("Score must be between 10 and 0")
       #starting again from the loop
       continue
   #incrementing count
   count=count+1
   #adding num to sum
   s=s+num
   #getting highscore
   if(highscore<num):
       highscore=num
   #getting lowscore
   if(lowscore>num):
       lowscore=num
#finding average
avg=s/count
#printing results
print("Average is "+str(avg))
print("Highest score is "+str(highscore))
print("Lowest score is "+str(lowscore))
print("Count is "+str(count))

Output:
