8E. Booleans Are Values

It is common for students get the idea that a boolean expression can only occur in a test, such as in an if-statement. But that is not true. If x is 2, then expression x > 0 has value true. Instead of

  if(x > 0)
  {
    return true;
  }
  else
  {
    return false;
  }

  return x > 0;

  if(x > y)
  {
    v = false;
  }
  else
  {
    v = true;
  }

  v = !(x > y);

  v = x <= y;
