What does the following loop do? val = 0 total = 0 while (val < 10): val = val + 1 total = total + val print( total)

print(total) => 45

Explanation:

# smells like Python...

val = 0 #initialize incrementor named 'val' at 0.

total = 0 #initilize accumulator named 'total' at 0.

while (val < 10): #look to execute while val is less than 10.

 val = val + 1 #increment val (val++) by 1

  total = total + val #increment total by val (val+=total)

# Step: val = 0

## val => 1, total => 1

# Step: val = 1

## val => 2, total => 3

# Step: val = 2

## val => 3, total => 5

# Step: val = 3

## val => 4, total => 9

# Step: val = 4

## val => 5, total => 14

# Step: val = 5

## val => 6, total => 20

# Step: val = 6

## val => 7, total => 27

# Step: val = 8

## val => 9, total => 36

# Step: val = 9

## val => 10 (END_LOOP), total =>  45

print(total) #print variable 'total'

something will pop up that says “know the answer? answer now! ” and you click on it and write your answer. after you are done, submit it.
