Section 1.22 Assessment: Pre/Post Operators
Subgoals for evaluating an assignment statement.
- Determine resultant data type of expression
- Update variable for pre operators based on side effect
- Solve arithmetic equation, operator precedence
- If = statement, is Left Hand Side (LHS) a variable? Check data type of copied value against data type of variable
- Update variable for post operators based on side effect
