Program in Python
val = 0
total = 0
while (val < 10):
val = val + 1
total = total + val
print(total)
Answer:
Prints the sum of the numbers from 1 to 10.
Explanation:
Given
The above lines of code
Required
What does the loop do?
To know what the loop does, we need to analyze the program line by line
The next two lines initialize val and total to 0 respectively
<em>val = 0 </em>
<em>total = 0 </em>
The following iteration is repeated while val is less than 10
while (val < 10):
This increases val by 1
val = val + 1
This adds val to total
total = total + val
This prints the value of total
print(total)
Note that the loop will be repeated 10 times and in each loop, val is incremented by 1.
The values of val is 1 to 10.
The summation of these value is then saved in total and printed afterwards.
<em>Hence, the loop adds numbers from 1 to 10</em>
