1.12.1. Expressions-WE9-P1¶
Subgoals for evaluating an assignment statement
Determine resultant data type of expression
Update variable for pre-increment or pre-decrement operators (side effect)
Evaluate arithmetic expression according to operator precedence
If an assignment statement (=), is Left Hand Side (LHS) a variable? Check data type of value against data type of variable.
Update variable for post-increment or post-decrement operators (side effect)
For the assignment statements below, give the new value of the assigned variable. Each problem is independent of the others (e.g. Question 2 does not depend on Question 1, only the “Given” code).
