What does the following statement output? for(b = 1; b > 3; ++b) System.out.print(b + " ");

nothing

What does the following statement output? for(a = 0; a < 5; ++a) System.out.print(a + " ");

0 1 2 3 4

If j=5 and k=6, then the value of j++ == k is _______________

false

What does the following statement output? for(f = 1, g = 4; f < g; ++f, --g) System.out.print(f + " " + g + " ");

1 4 2 3

What does the following program segment output? for(f = 0; f < 3; ++f) for(g = 0; g < 2; ++g) System.out.print(f + " " + g + " ");

a. 0 0 0 1 1 0 1 1 2 0 2 1

What does the following program segment output? for(m = 0; m < 4; ++m); for(n = 0; n < 2; ++n); System.out.print(m + " " + n + " ");

The prefix ++ is a ___________________ operator

a. unary

What does the following program segment output? d = 0; do { System.out.print(d + " "); d++; } while (d < 2);

b) 0 1 NOT 012 because 2<2= false!
