- Note that the boolean expression appears at the end of the loop, so that the statements in the loop are executed once before being tested for the logical condition.
- If the Boolean expression is true, the control jumps back to execute the operators, and they in the loop are executed again.
- This process is repeated until the logical expression becomes false.
