Introduction to Programming Chapter 04 - Terms
| Decision Structure [function] | A decision structure [AKA selection structure] allows a program to perform actions only under certain conditions. |
| NOT operator | Takes a Boolean expressions as its operand and reverses its logical value. |
| Short-Circuit Evaluation | AND: If the expression to the left of the operand is false, right side is not checked. OR: If the expression to the left of the operand is true, right side is not checked. |
| OR operator | Takes two Boolean expressions as operands and creates a compound Boolean expression that is true when either of the subexpressions is true. |
| && | AND operator |
| | | | OR operator |
| !. | NOT operator |
| AND operator | Takes two Boolean expressions as its operand and creates a compound Boolean expression that is true only when both subexpressions are true. |
| Case Structure [AKA] | Multiple Alternative Decision Structure |
| Case Structure [function] | Allows you to test the value of a variable or an expression and then use that value to determine which statement or set of statements to execute. |
| Decision Structure [AKA] | Selection Structures |
| conditionally executed | performed only when a certain condition is true. |
| Single Alternative Decision Structure | Provides only one alternative path. |
| You can use Decision Statements alone to create a complete program? T/F | False |
| If Clause | The program line that begins with IF |
| condition | Any expression that can be evaluated as either true or false. AKA Boolean Experssion |
| Boolean Expressions | Expressions that can be evaluated as either true or false. |
| Relational Operator [function] | Determines whether a specific relationship exists between two values. |
