1. b) c) and e) since 34 and 8Z start with a digit and min.value
   contains a '.'

2. a) b) and d)

3. z is not initialized.

4. a) 1 / z * (x + y)
   b) x*y + x*z - 3
   c) x + y/2
   d) (x + y)/ 2
   e) (a + b)*c

5. a) The semi-colon at the end of the if line will result in the
      compiler flagging the else as an error.

   b) The semi-colon after the else means that the null statement is
      executed if the condition is false and so x++ will always be
      executed.

   c) Missing semi-colon after the assignment statement following the
      if.
 
   d) Two problems. The semi-colon after the while and the x++ will
      always be executed.

6. a) 2
   b) 18
   c) 20
   d) 18 

7. a) Truncation, x will be assigned the value 2.
   b) x will be assigned the value 1.0
   c) y will be assigned the value x + 2.1 since (3/2) evaluates to 1.
   d) As for c). Several fixes, but double(3)/2 would work.

8. int a, b, c;
   cin >> a >> b;
   c = testfunc(a, b);  
  
9. int sum=0; 
   if (x == 1)
      {
         sum = sum + 1;
         cout << "Add one \n";
      }
   else if (x == 2)
      {
         sum = sum + 2;
         cout << "Add two \n";
      }
   else if (x == 3)
      {
         sum = sum + 3;
         cout << "Add three \n";
      }
   else
      cout << "Ouch \n";

10.a) XXX
   b) XXXX

11. a) int i;
       for (i=1; i<=5; i=i+2)
          cout << "loop\n";   

    b) int j;
       for (j=10; j>0; j--)
          cout << "loop\n";
