Short Answer Assignment 5.1

1. Conditionally executed is a single alternative decision structure. It provides only one alternative path of execution. The action is conditionally executed because it is performed only when a certain condition is true. 2. Using the IF statement will be the way to go because it is a dual alternative decision structure. 3. The case structure would be the most straightforward to use. 4. The and operator takes two Boolean expressions as operands and creates a compound Boolean expression that is true only when both sub-expressions are true. 5. The OR operator takes two Boolean expressions as operands and create a compound Boolean expression that is true when either of the sub-expressions are true. 6. The And operator 7. A flag is a Boolean variable that signals when some conditions exists in the program.
