1. Given the following structure definition, which of the following
   is syntactically correct.

   struct new           a. v[1].a = 1;         b. v.a[1] = 1;
   {
      int a[2];         c. v.b[1] = 1.5;       d. v[1].b = 1.5;
      float b;
   };
   struct new v;



2. Given the following structure definition, which of the following
   is syntactically correct.

   struct new           a. v[1].a[1] = 1;      b. v[0].b[1] = 1;
   {
      int a;            c. v.b[1] = 1.5;       d. v.a[1]    = 1.5;
      float b[2];
   };
   struct new v[3];


3. Compute the dot product of


   (3, 4, 1) dot (2, -1, 3) =


4. Compute the length of the vector (-1, 2, 1) (No calculators
   are needed -- you may leave the square root symbol in your answer).


   || (-1, 2, 1) || =



5. Compute the vector difference of:


   (1, 2, 4) - (2, -1, 3) =
