Which of these best describes the output of these 2 code segments?

• Segment 1 and Segment 2 produce the same output.

• Segment 1 produces a larger sum than Segment 2, because the update increments by 2.

• Segment 2 produces a larger sum than Segment 1, because no numbers are skipped in the for loop.

• Segment 1 only sums the odd numbers from 1 to 20, while Segment 2 only sums the even numbers from 0 to 20.

• Segment 1 and Segment 2 would produce the same output if the initialization of i in Segment 1 was changed from 1 to 0.

Complete the code to produce the following output

public static void main(String [ ] args)

{

for (/* initialization */; / * Boolean Expression */; number++)

{

System.out.print(number * 3 + " ");

}

System.out.println( );

}

Output: 0 3 6 9 12 15 18 21 24 27 30

• int number = 0; number < 10;

• int number = 0; number <= 10;

• int number = 3; number < 10;

• int number = 3; number <= 10;

If you have $200 in a bank account that earns 10% interest per year, how much would you have after saving that money for 50 years?

Write a code segment (using a for loop) to calculate and display the total amount that you would have after 50 years.

Which type of a loop is a for loop?

• pre-test

• post-test

• mid-test

• zero-test

if the condition of a for loop is false the first time it is checked:

• There will be a syntax error

• The loop will never end

• The loop will execute only once
