Add up 1 to 100
Add every whole number from 1 to 100 and print the result.
This is a running total: start at 0 and add the loop variable on every pass. The starter adds 1 to 10, so you only need to change where the range stops. The young Carl Friedrich Gauss is said to have found this answer in his head by pairing 1 + 100, 2 + 99 and so on.
