What do these code fragments print?
a.int n = 1; int m = -1;
if (n < -m) { cout << n; } else { cout << m; }
b.int n = 1; int m = -1;
if (-n >= m) { cout << n; } else { cout << m; }
c.double x = 0; double y = 1;
if (abs(x - y) < 1) { cout << x; } else { cout << y; }
d.double x = sqrt(2); double y = 2;
if (x * x == y) { cout << x; } else { cout << y; }Homework Answers
