Subsection 1.25.1 Subgoals 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)
