Section 1.13 Assessment: Operation Precedence

Subgoals for evaluating an assignment statement.

  1. Determine resultant data type of expression
  2. Update variable for pre operators based on side effect
  3. Solve arithmetic equation, operator precedence
  4. If = statement, is Left Hand Side (LHS) a variable? Check data type of copied value against data type of variable
  5. Update variable for post operators based on side effect
