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