1.11. Assessment: Boolean Relational Operators

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)

Q1: Given the following, what value is stored in variable answer?

int x = 5, y = 3, z = 1;

boolean answer;

answer = x <= z;

• true
• false

Q2: Given the following, what value is stored in variable answer?

int x = 5, y = 3, z = 1;

boolean answer;

answer = y >= z;

• true
• false

Q3: Given the following, what value is stored in variable answer?

int x = 5, y = 3, z = 1;

boolean answer;

answer = x > z + y;

• true
• false

Q4: Given the following, what value is stored in variable answer?

int x = 5, y = 3, z = 1;

boolean answer;

answer = z < y - z;

• true
• false

Q5: Given the following, what value is stored in variable answer?

int x = 5, y = 3, z = 1;

boolean answer;

answer = ((x * y) + (x * z)) != ((z * x) + (y * x));

• true
• false
