Question 1

What is the value in count after the following loop is executed?

int count = 0;
do {
System.out.println("Welcome to Java");
} while (count++ < 9);
System.out.println(count);

◦ 8
◦ 9
◦ 10
◦ 11
◦ 0

Question 2

Analyze the following statement:

double sum = 0;
for (double d = 0; d < 10;) {
d += 0.1;
sum += sum + d;
}

◦ The program runs in an infinite loop because d<10 would always be true.
◦ The program compiles and runs fine.
◦ The program has a compile error because the adjustment is missing in the for loop.
◦ The program has a compile error because the control variable in the for loop cannot be of the double type.
