## Section1.28Assessment: Boolean Logical Operators

### Subsection1.28.1Subgoals for evaluating an assignment statement

1. Determine resultant data type of expression
2. Update variable for pre-increment or pre-decrement operators (side effect)
3. Evaluate arithmetic expression according to operator precedence
4. If an assignment statement (=), is Left Hand Side (LHS) a variable? Check data type of value against data type of variable.
5. Update variable for post-increment or post-decrement operators (side effect)
