- do stepA
- do stepB
- if conditionC is true
- then do stepD
- else
- do stepE
- end if
- while conditionF is true
- do stepG
- end while

Line 8 check if conditionF is true then repeatedly execute stepG. These are examples of pretest a condition will must be met (pretest passed) before a block of codes can be executed. This pretest can be seen in if-else statements and also the while condition.
