The do-while loop is an exit-condition loop. This means that the body of the loop is always executed first. Then, the test condition is evaluated. If the test condition is TRUE, the program executes the body of the loop again. If the test condition is FALSE, the loop terminates and program execution continues with the statement following the while.
1. Break will kill the nearest/innermost loop that contains the break. In your example, the break will kill the do-while, and control jumps back up to the for () loop, and simply start up the next iteration of the for (). However, since you're modifying x both in the do () AND the for () loops, execution is going to be a bit wonky.Key Differences Between while and do-while Loop.
