n = 10;
while
(n > 0)
{
System.out.println("Hello " + n);
n = n - 2;
}
32. The output is
1024 10
. The second number is the log to the base 2 of the first
number. (If the first number is not a power of 2, then only an approximation to
the log base 2 is produced.)
33. The output is
1024 1
. The semicolon after the first line of the
for
loop is probably
a pitfall error.
34. The output is too long to reproduce here. The pattern is as follows:
1 times 10 = 10
1 times 9 = 9
.
.
.
1 times 1 = 1
2 times 10 = 20
2 times 9 = 18
.
.
.
2 times 1 = 2
3 times 10 = 30
.

.
35. a. A
for
loop
b. and c. Both require a
while
loop because the input list might be empty. (A for
loop also might work, but a
do-while
loop definitely would not work.)
36. This is an infinite loop. The first few lines of output are
10
12
16
19

37. This is an infinite loop. The first few lines of output are
n == 1
limit == 10;
n == 2
limit == 3
n == 3
