Section 1.5 Expressions-WE2-P1

Subsection 1.5.1 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 all given problems below indicate if the code is valid or invalid. Each problem is independent of the others (e.g. Question 2 does not depend on Question 1, only the “Given” code).

Subsection 1.5.2 Expressions-WE2-P1

Given

int alpha = 2, beta = 1, delta = 3, gamma;
final int eta = 10;
double omega = 2.5, theta = -1.3, kappa = 3.0, lambda, rho;
