Answer:
Following are the program in the Python Programming Language.
#declare variables and initialize to 0
s=0
n=0
avg=0
#set the infinite while loop
while(True):
#get input from the user
score=input()
#set if statement to break loop
if(score =="stop"):
break
#otherwise, perform calculation
else:
n+= 1
s=s+ int(score)
avg= s/n
#print average of the input
print ('average: ',avg)
<u>Output</u>:
58
96
34
15
stop
average: 50.75
Explanation:
<u>Following are the description of the program</u>.
- Firstly, set three variable that is 's' for sum, 'n' for count and 'avg' for average and initialize them to 0.
- Set the infinite while loop and inside it, set variable 'score' that get input from the user then, set the if conditional statement for break the loop, otherwise we calculate the sum of the user input and calculate its average.
- Finally, we print the result with message.
