Section 1.27 Expressions-WE9-P1

Subsection 1.27.1 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)
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).

Subsection 1.27.2 Expressions-WE9-P1

A truth tables shows all possible combinations of input values for a set of variables, and the corrsponding outputs.
The “Line #” column of the chart below corresponds to the following multiple choice questions. Complete this truth table by choosing “true” or “false” for each Line #.
