Question 1

Is the following loop correct?

for (; ; );

◦ Yes
◦ No

Question 2

Analyze the following fragment:

double sum = 0;
double d = 0;
while (d != 10.0) {
d += 0.1;
sum += sum + d;
}

◦ After the loop, sum is 0 + 0.1 + 0.2 + 0.3 + ... + 1.9.
◦ The program may not stop because of the phenomenon referred to as numerical inaccuracy for operating with floating-point numbers.
◦ The program does not compile because sum and d are declared double, but assigned with integer value 0.
◦ The program never stops because d is always 0.1 inside the loop.
