The following loop is executed as long as the value of i is less than 10. Each time the loop is executed, sum is set equal to the value it had at the beginning of the loop, plus the current value of i. i is then incremented by one, and the two values are printed out. At the end of the loop, the condition is checked again; since i starts with the value 1 and is increased by one each time, the loop will be executed 9 times. |
