What is sum after the following loop terminates?

Question

int sum = 0;
int item = 0;
do {
item++;
if (sum >= 4)
continue;
sum += item;
}
while (item < 5);
a. 6
b. 7
c. 8
d. 9
e. 10

Answer 1

a In this loop, when sum >= 4, the continue statement is executed to exit the current iteration so the next statement sum += item after the if statement will not be executed. The loop keeps adding item to sum for item 1, 2, 3, and so on. So sum is 1, 2, and 6 . When sum is 6, sum >=4 is true, the continue statement is executed to skip the rest of the iteration. When the loop ends, sum is still 6 . So, the correct answer is A.
