}


output sum.





a. 9


b. 7


c. 4


d. 1





2. What would be output by the following section of code ?

a. 4


b. 0


c. 8


d. 6





3. Given the following method (you may assume it has all compiled correctly so there are no syntax errors), what will be output?

First problem the answer is 4.


Second problem the answer is 8


Third problem the answer is 2, 4, 6, 8.





Why?





1st Problem:





sum 10


i 1


n 3





while i%26lt;=n


{


sum = sum -1


}


output sum





10 - 6 = 4, thats the output of sum





Second problem:





You end up having the value of 4+4 which is 8.





And for the last problem, the only numbers that will give you %2==0 are 2, 4, 6, 8
