From this explanation I was given for this code segment: Explanation: Iteration 1: i = 200 After entering the loop: i %2 == 0 i.e 200%2 == 0 will be true , So prints 200 Iteration 2: i = i/3 = 200/3 = 66 After entering the loop: i %2 == 0 i.e 66%2 == 0 will be true , So prints 66 Iteration 3: i = i/3 = 66/3 = 22 After entering the loop: i %2 == 0 i.e 22%2 == 0 will be true , So prints 22 Iteration 4: i = i/3 = 22/3 = 7 After entering the loop: i %2 == 0 i.e 7%2 == 0 will be false , So 7 is not printed Iteration 5: i = i/3 = 7/3 = 2 After entering the loop: i %2 == 0 i.e 2%2 == 0 will be true , So 2 is printed Iteration 6: i = i/3 = 2/3 = 0 Does not meet the condition, so exits from the condition. I don’t understand why there are 6 different iterations in this code segment and what i > 0 in the for loop and System.out.print(i + “ “) mean. Can you give me an in depth explanation as to why these things occur?

### CHAPTER 5 REVIEW DRILL

Answers to the review questions can be found in Chapter 13.

#### 1. Consider the following code segment:
```java
for (int i = 200; i > 0; i /= 3)
{
if (i % 2 == 0)
System.out.print(i + " ");
}
```

What is the output as a result of executing the code segment?

(A) 200 66 22 7 2
(B) 66 22 7 2
(C) 200 66 22 2
(D) 200 66 22
(E) 7

#### 2. Suppose p and q are declared as boolean variables and have been initialized to unknown truth values.

What does the following boolean expression evaluate to?

*Note: This part of the question requires a specific boolean expression to be provided for evaluation, which is missing in the image.*
