1.10.1. Expressions-WE8-P1

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)

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).
