   // Size of an Array
   #include <iostream>
   using std::cout;
   using std::endl;
   
   int main()
   {
       int a[5] = { 0, 2, 4, 6, 8 };
       cout << sizeof(a[0]) << endl;
       cout << sizeof(a) << endl;
       return 0;
   }
   
   
2. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   // Character Array
   #include <iostream>
   using std::endl;
   using std::cout;
   
   int main()
   {
       char s[] = "NCNU";
       char horse[] = "~/-\\^";
       char c = horse[4];
       char* p = &horse[4];
       cout << sizeof (s) << c << (p - horse) << endl;
       return 0;
   }
   
   
3. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).

   #include <iostream>
   using std::cout;
   using std::endl;
   
   int main()
   {
       int n = 2017;
       int* p = &n;
       cout << (*p) ++ << endl;
       cout << (*p) << endl;
       cout << ++ (*p) << endl;
       return 0;
   }
