The pseudocode above shows that there is a pretest before some codes are executed. For example, line 3 check if condition is true then only execute stepD otherwise execute stepE. 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.
