Test a condition for true or false
Once again, for pseudocode in Figure 2, there is only one entry point and one exit point.
The first thing that happens following entry is that some condition is tested for true or false.
If the condition is true, one or more actions are taken in sequence and control exits the structure.
If the condition is false, none, one or more actions are taken in sequence and control exits the structure.
(Note the inclusion of the word none here.)
