The loop does not have a termination condition, and it will continue to execute as long as the sum is less than or equal to 1000. However, the statement inside the loop decreases the value of sum by 30 each time it executes. Therefore, if sum starts out greater than 1000, the loop will never terminate, resulting in an infinite loop. To fix this, the statement inside the loop should increase the value of sum.
